Product Powerware Plus 24kVA
Application Spirits Distributor
Synopsis Customer called Nationwide Power for their 20-year old Powerware Plus UPS unit after experiencing a power outage. Their generator is currently under repair, and so the load did not switch to the generator during the outage. After the outage, the UPS unit went down and was in alarm. Alarm shown: Inverter Shut Down.
Preliminary Actions

Through established troubleshooting protocol, the Critical Power Professional™ (CPP™) was able to assist the customer in bringing the Powerware Plus UPS unit back online within just 10 minutes.

Nationwide Power CPP’s are equipped with troubleshooting protocol for all major makes and models of UPS systems, including those that are deemed obsolete by the OEM.

Resolution Once the batteries had an opportunity to recharge, the UPS system was fully operational with the load attached and protected.
Root Cause After the power outage, and due to the generator being inoperable, the UPS unit depleted its batteries to end voltage. Because this Powerware Plus UPS unit has been properly serviced over the past 20 years, the system continues to operate as designed.

 Case Study # 138 | Powerware 9315 Repair (End of Life)

 

Nationwide Power™ is the leading provider in the critical power supply industry. Our core business is the sales and service of uninterruptible power supplies and UPS batteries, along with supporting other critical power components such as emergency generators, switch gear, and HVAC. We publish critical power related case studies, highlighting best practices and quality standards.

In this case study, we highlight a service call for a Powerware 9315 that has reached its end of life, per the OEM. As the Powerware 9315 is no longer in production and deemed obsolete, very few UPS service providers have the ability to continue support.

Nationwide Power houses over $10 million in equipment and parts inventory. Combined with a state-of-the-art testing and repair lab, Nationwide Power is equipped to service a wide variety of UPS units that have passed their OEM stated end of life, including the Powerware 9315.

Product Powerware 9315 UPS (end of life)
Application Regional Hospital
Synopsis

Nationwide Power was on site for a regularly scheduled UPS preventive maintenance (PM) call. Upon restarting the Powerware 9315 after the major PM from maintenance bypass, the bypass contactor began chattering open and closed while applying bypass input.

After standard troubleshooting, it was confirmed that the following parts required replacement due to age:

  • 3-phase relay for K5
  • Bypass control board
  • Aux switch for K5

These parts were ordered through the Nationwide Power Corporate Warehouse on a Friday and arrived on site on Monday.

The Critical Power Professional™ arrived back on site to install the parts, and the Powerware 9315 UPS unit was placed back in service as fully functioning.

Preliminary Actions Once the parts needed to service the Powerware 9315 were identified, those parts were immediately shipped to the site, which arrived the next business day. This was only possible due to Nationwide Power’s expansive stock of parts inventory for all major UPS makes and models, including obsolete equipment.
Resolution

Per the OEM, the Powerware 9315 has reached end of life. Many service providers would recommend a full equipment replacement, due to not having access to parts inventory to resolve issues on obsolete units. However, Nationwide Power was able to assist the customer and further extend their unit’s end of life.

Note: Nationwide Power customers have the option of selecting a full-service contract where all emergency calls and time & material rates are covered under the annual contract price.

When customers hire Nationwide Power for preventive maintenance checks without a full-service contract, all time & material rates and/or emergency calls are billed separately.

Full-service contracts have many benefits to the customer, including priority service, expedited order processing and shipping, and guaranteed parts inventory.

On obsolete equipment, securing a full-service contract becomes increasingly more important. Nationwide Power is diligent in ensuring that all units under contract have the ability to be reasonably serviced. By electing a full-service contract, customers have a sense of security knowing that there is ample parts inventory to service their unit as long as the contract is in place. Priority service is given to customers under full-service contracts.

Not only does a full-service contract provide an extra level of security and comfort for the customer, it is often more cost effective as well. In this example, the itemized preventive maintenance appointments and time & material rates for the above repairs would equate to roughly two years of a full-service contract.

Root Cause As UPS units age, various parts require replacement or maintenance over time. The items mentioned in this case study required replacement due to normal use over time.

Nationwide Power™ is the leading provider in the critical power supply industry. Our core business is the sales and service of uninterruptible power supplies and UPS batteries, along with supporting other critical power components such as emergency generators, switch gear, and HVAC. We publish critical power related case studies, highlighting best practices and quality standards.

In this case study, we highlight an emergency service call for a 93PM 16kVA UPS that went into alarm after a power outage. The 93PM UPS was under a full-service UPS preventive maintenance contract, which means the customer’s service call was given first priority. Additionally, the customer did not incur any out-of-pocket cost for the service call.

 

Product Eaton 93PM 16kVA UPS
Application National Insurance Company
Synopsis

The customer contacted Nationwide Power after a brief power outage that resulted in an alarm on their Eaton 93PM UPS. As a full-service contracted customer, the customer received priority service, with their local Critical Power Professional™ (CPP) arriving on site within two hours.

The CPP identified the alarm as a Maintenance Bypass Breaker trip and began to troubleshoot the cause. With a thermal camera, the CPP found that the Maintenance Bypass Breaker had a hot spot in excess of 100° F. The next step was to check the electrical connections, and it was found that all three connections on the load side of the breaker were loose.

Connections were tightened and the Eaton 93PM UPS was put back online with no alarms. At that point, the customer decided to proactively replace the breaker to prevent possible future alarms.

Preliminary Actions Customer had a full-service contract which allowed for Nationwide Power to immediately dispatch a Critical Power Professional to the site. The local CPP arrived on site within two hours and the unit was placed back in service with no alarms within three hours from the initial call.
Resolution Because the customer has a full-service contract with Nationwide Power, there was no out-of-pocket cost to the customer for the emergency site visit.
Root Cause Loose wire connections at the breaker level caused the alarm after a power outage occurred.

Nationwide Power™ is the leading provider in the critical power supply industry. Our core business is the sales and service of uninterruptible power supplies and UPS batteries, along with supporting other critical power components such as emergency generators, switch gear, and HVAC. We publish critical power related case studies, highlighting best practices and quality standards.

In this case study, we highlight an emergency service call for an MGE EPS 6000 UPS where the Critical Power Professional™ arrived on site and fully resolved the issue within just 2.5 hours of the initial call.

To protect the confidentiality of the customer, the customer will be referred to as Company A.

Product MGE EPS 6000 UPS
Application Managed Service Provider
Synopsis

Company A contracted Nationwide Power to perform preventive UPS maintenance for multiple UPS units on site, varying in make, model, and kVA.

The customer called into our 24/7 Emergency Service line just before business hours, looking for technical support on an alarm for their MGE EPS 6000 UPS unit. After identifying the alarm as an Inverter Fault, the Critical Power Professional™ (CPP) attempted to walk the customer through the alarm over the phone. When the customer expressed discomfort with operating the external maintenance bypass, the CPP was dispatched and arrived on site within the hour. Once on-site, the CPP resolved the alarm on the MGE EPS 6000 UPS, restored the unit’s load, and performed additional testing to confirm that the issue was fully resolved.

Preliminary Actions After attempting to resolve over the phone without success, the Critical Power Professional™ requested an emergency dispatch. On-site support within the hour was made possible due to:

  1. An Emergency Service Contract between Company A and Nationwide Power, which allowed for immediate escalation.
  2. The strategic location of Nationwide Power’s Field Engineer team across the United States, with sufficient physical presence in all major markets.
Resolution

Reviewed activities and discovery with the customer. Reviewed alarms, performed appropriate testing, and cleared the alarms. All alarms cleared and the UPS went back online with no alarms carrying 106 kVA. Monitored the UPS for a re-occurrence of the “Inverter Fault” alarm initiated by the ALBZ inverter power supply board. UPS ran online for one hour without any issues.

As the customer was under an Emergency Service Contract with Nationwide Power, there was no out-of-pocket expense to the customer.

Root Cause At the time, the region was experiencing very high winds from a storm that was passing through, and this particular site is known to have severe issues with electrical distribution.

Case Study

Case Study #135 | Emergency I/O Board Replacement – Eaton 9355 30kVA UPS

 

At Nationwide Power, we talk about quality often. We define quality as conformance to requirements, and the result of a carefully constructed cultural environment.

As a direct result of establishing processes and procedures, which are then closely adhered to throughout the service chain, we are able to service our customers seamlessly and deliver on the promises we make. Our entire team at Nationwide Power is committed to doing the job right the first time and eliminating any headache or unnecessary expense to our customers and their companies.

While delivering on quality is free, the price of non-conformance – or the price when quality standards aren’t met – can be quite costly.

In this case study we highlight an emergency call on an Eaton 9355 30kVA UPS unit. As a result of a well-established company infrastructure, the issue was fully resolved within 24 hours with no out-of-pocket cost to the customer.

Product Eaton 9355 30kVA UPS
Application Hospital
Synopsis Customer is under a 2X / YR full-service preventive maintenance contract. Within just a couple weeks of their next regularly scheduled PM, the customer experienced a major failure of the main I/O board, which required immediate replacement to protect their critical loads.
Preliminary Actions An emergency ticket was created. The I/O board for the 9355 30kVA UPS was confirmed in-stock at the corporate warehouse. The parts were scheduled for immediate first overnight shipping cross-country (this particular shipment was quicker via first overnight than counter-to-counter). The Field Engineer was scheduled to be on-site at the time of the part’s arrival.
Resolution Since the customer was under a full-service contract with Nationwide Power, our Field Engineer was able to prioritize their emergency service needs accordingly. The faulty I/O board was replaced and the UPS system was back in service and fully operational in just 24 hours. As with all full-service contracts with Nationwide Power, the customer incurred no out-of-pocket expenses for labor, shipping, or material.
Root Cause The UPS unit’s batteries were approaching the 5-year mark and were due for replacement. Aging batteries can pull on the DC circuit, ultimately resulting in a faulty pre-charge circuit in the I/O board.

What went right:

At Nationwide Power, we have many factors that set us apart from other independent service providers, which have given us the opportunity to lead the industry in service and quality. Among these are:

  • 24/7/365 customer support
  • 57,000 square foot warehouse with over $10 million in parts and equipment inventory (not all service providers have parts, beware of PM only contracts)
  • Conveniently located within 10 miles of McCarran International Airport in Las Vegas, allowing for same-day or next-day expedited parts shipping
  • Systems and processes in place that allow our team to respond quickly and coordinate smoothly, particularly in emergency situations.

 

What could have gone very wrong:

Unfortunately, there are “service providers” in our industry who offer full-service contracts on equipment that they do not have parts, training, or support to actually service. Often, these “service providers” will call Nationwide Power directly in an effort to source parts and/or subcontract the work. Nationwide Power does not operate as a parts dealer nor subcontractor, and as such, is unable to offer assistance to these “service providers.”

Additionally, Nationwide Power has invested heavily in software and infrastructure systems that allow for quick and seamless action between departments and team members. There is no scrambling. There are no fires to put out. The team simply follows a process and protocol that works.

Without all the right pieces in place, any “service provider” would have a challenging time responding to an emergency service call and providing a full resolution in a timely manner.

When shopping for a critical power service provider, shop for quality – not just price.

Nationwide Power provides 24/7/365 technical support to ensure that everything operates and transitions successfully before, during, and after any power outage.

Case Study # 134 | Emergency Lighting UPS – Manufacturer Defect

Nationwide Power™ is the leading provider in the critical power supply industry. Our core business is the sales and service of uninterruptible power supplies and UPS batteries, along with supporting other critical power components such as emergency generators, switch gear, and HVAC. We publish critical power related case studies, highlighting best practices and quality standards.

Our Critical Power Professionals™ (CPP™) come across unique situations regularly, where they are required to pull from their 22+ average years of industry experience to troubleshoot and resolve unexpected issues.

In this case study, we review the details of a manufacturer defect on an Emergency Lighting UPS that was identified during a routine battery installation.

To protect the confidentiality of the customer, the customer will be referred to as Company A.

Product Emergency Lighting UPS
Application Emergency Lighting
Synopsis

Company A contracted Nationwide Power to perform the first battery replacement on their Emergency Lighting unit. After successfully performing the battery replacement, the CPP™ attempted to install the DC fuse. Instead of the unit being discharged after using the discharge feature, it was unsuccessful and there was a spark.

The CPP referred to the manual in an effort to troubleshoot, which did not sufficiently address the issue. The CPP continued to troubleshoot by measuring the voltage differential, which was approximately 250 VDC. The CPP proceeded to once again use the discharge feature, but the voltage went up to 270 VDC instead of going down.

After additional troubleshooting, the CPP determined that the Recharge and Discharge buttons were misconfigured, and thus the Recharge button caused the voltage to lower to the appropriate level for installing the fuse without a spark. Once this misconfiguration was identified, the work was able to be completed, the UPS components were relabeled, and the system was brought back to a normal operating status.

Preliminary Actions The Critical Power Professional (CPP) encountered an issue with the Emergency Lighting UPS that had existed since the unit was manufactured, and remedied it based on his own expertise.
Resolution Although our CPP was exposed to an unknown hazard, he was also able to remedy the situation on-site. Nationwide Power’s team of Critical Power Professionals average over 22 years of industry experience. Where other service providers may have deemed the unit as inoperable, our team was able to complete the job to the customer’s satisfaction.
Root Cause Unknown. If the root cause was in fact due to a manufacturer defect, the unit would have been out of warranty by the time the defect was identified.
