Case Study #143 | Eaton 9395 450kVA

 

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. Our 57,000 square foot warehouse, with over $10 million in parts and equipment inventory, provides us the ability to service nearly all major makes and models of UPS equipment.

Additionally, Nationwide Power has built strong relationships with each of the original equipment manufacturers (OEMs) over the past two decades, allowing for the best possible support for our customers.

In this case study, a customer’s Eaton 9395 450kVA UPS system was in alarm. In collaboration with Eaton, the OEM, the issue was fully resolved within just 48 hours, and with no out-of-pocket expense to the customer.

 

Product Eaton 9395 450kVA
Application Aerospace and Defense Technology Company
Synopsis

A contracted customer called the 24/7 technical support line to report an Eaton 9395 450kVA UPS system in alarm status. After initial troubleshooting, Nationwide Power engaged the OEM. Thanks to the strong OEM relationships our team has established over the years, our customers have confidence in knowing that their equipment will be serviced in the best possible manner, which sometimes requires OEM involvement.

Since the customer had a full-service contract with Nationwide Power, all expenses to repair the unit were covered by Nationwide Power, including the three OEM site visits.

Preliminary Actions

On a technical support call, a Nationwide Power Critical Power Professional™ conducted initial troubleshooting and found the universal power module (UPM) 2 to be offline and DC current in limited condition.

At this point, the OEM was engaged and arrived on site the same day. The Eaton Customer Service Engineer (CSE) determined that a wiring harness had been rubbing against a fan blade that shorted out the harness and caused a DC overcurrent on UPM 2. Parts were ordered for next day delivery, and the Eaton CSE returned the next day to complete the repair.

After replacing the bad harness, the positive DC current was still measuring high. After further troubleshooting, it was determined that the DC link current transformer (CT) was damaged after they shorted out. Additional parts were ordered, and the OEM returned for a third site visit for final repair.

Resolution

Replacement parts were shipped with priority service. Once the damaged CT was replaced, all alarms were cleared. Preventive maintenance (PM) was performed and the Eaton 9395 450kVA UPS was calibrated. There were no further issues and the UPS was left online and supporting the critical load.

Occasionally, it is necessary to engage the OEM during a service call, either due to proprietary software or escalated repair needs. Over the past two decades, Nationwide Power has been committed to building strong relationships with all major OEMs, in an effort to provide a seamless service to our customers.

Whenever an OEM is engaged under a full-service contract, there is no out-of-pocket cost to the customer.

Root Cause

From time to time, at no fault to the customer, component parts in a UPS system fail.

Because this customer has a full-service contract with Nationwide Power, the customer had no out-of-pocket expenses, which otherwise would have included time and material for the original troubleshoot, shipping expense, and the additional cost to engage the OEM.

Additional Reading

Not all critical service providers have made the commitment to building strong relationships with each of the OEMs they support. As a result, there may be times when these service providers attempt to self-perform tasks that should require OEM engagement.

Case Study # 140 | Eaton 9PX – Installation Error by Competitor

Case Study # 140 | Eaton 9PX – Installation Error by Competitor

Case Study

Case Study # 140 | Eaton 9PX – Installation Error by Competitor

 

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.

At Nationwide Power, we believe strongly in providing quality service for our customers, and periodically, we try to educate businesses on the value of selecting a qualified service provider.

In this case study, we highlight a service call from a non-contracted customer who needed assistance on several Eaton 9PX systems. The original service provider (not Nationwide Power) incorrectly installed the UPS units, and then became unresponsive post-installation.

 

Product Eaton 9PX
Application Technology Company
Synopsis

Nationwide Power was contacted for assistance after a previous service provider improperly installed several 9PX UPS units, causing intermittent system failure. The previous service company became unresponsive post-installation and was either unable or unwilling to provide resolution.

A Nationwide Power Critical Power Professional™ (CPP™) arrived on site and discovered that the Eaton 9PX units fed to robot tools upstairs. The robots perform an acid wash for a semiconductor wafer process and were located in a clean room. The customer said that the robot input voltage drops to about 90 Vac, which causes the low-voltage power supplies to drop out (+12, -12, +24, -24, various low voltages used by the robotic equipment to perform their unique functions). The UPS was setup as a 208 in/208 out configuration and they were told by the previous critical power company that they required an output transformer so the robot equipment would not see the voltage drop. The external transformer was configured for a 208 Vac in and a 208 Vac output.

The CPP™ noted this as a classic example of the “Single Phase 208 Vac” problem with the “Low Leg (88 Vac from line 1 neutral)”.

With over 22+ years of average industry experience, our Critical Power Professionals are among the most experienced in the industry and have completed an extensive and comprehensive training curriculum spanning all major UPS manufacturers.

Preliminary Actions The solution was tested on the first system that was offline, which included switching the output of the transformer to 240Vac single phase (which provided 120Vac from each phase to neutral), configuring input voltage accordingly, and then restarting the system. Once the solution was tested and confirmed, and the UPS system was no longer failing, the solution was applied to the remaining UPS systems.
Resolution Input/output configuration was corrected and, as a result, all UPS systems were fully operational.
Root Cause

The root cause of this situation was poor workmanship performed by the original service provider, as the original service provider failed to complete the scope of work for the Eaton 9PX UPS installation.

At Nationwide Power, we take the work we do very seriously and place a lot of value on completing projects completely and without error the first time, avoiding any headaches for our customers down the road. We follow the principles of Philip Crosby closely, measuring quality by a zero-defect environment. Choosing a well-qualified, reputable critical power service provider would have eliminated the need for rework for this customer.

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 contracted customer with a 20-year old Powerware Plus UPS that experienced an inverter shutdown issue. The customer called into our Tech Support Center for immediate phone support with a Critical Power Professional™, which is an exclusive, no-cost benefit for our contracted customers.

 

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.
