What does a maintenance visit check on an Eaton 9395?
2:09. On an Eaton 9395 the daily list is short: uncluttered surroundings, front intakes and top exhaust free, room within environment, Online lamp lit. Monthly: monitor the parameters; the filters sit behind the front panels, so the filter check belongs to the visit. The cabinet is not to be operated with doors open or panels removed (p. 248), and battery plants are replaced in planned outages. Source: Eaton's Power Xpert 9395 manual 164201764 Rev 18.

0:00 What does a maintenance visit check on an Eaton 9395? What does a maintenance visit check on an Eaton 9395? The daily list is short, the monthly list adds two items, and the cabinet itself belongs to a scheduled visit.
0:11 What is on you daily? What is on you daily? Keep the surroundings uncluttered, keep the front intakes and the top exhaust free, keep the room within its specified environment, and confirm the Online lamp.
0:22 And monthly? And monthly? Monitor the system parameters. And check the UPS air filters, located behind the front panels or door, and wash or replace them as necessary, exactly as the manual assigns to the user.
0:35 What does the visit look for? What does the visit look for? The wear parts: fans, capacitors and the battery string, covered before they become alarms. For the 9395 family, Eaton's lifecycle schedule puts the AC capacitors outside the modules at about year 7 and the DC capacitors inside the modules at about year 10.
0:56 Which batteries does it take? Which batteries does it take? Lead-acid or lithium-ion, and 9395 battery plants are large: replacements are planned outages, matched to the existing cabinet configuration.
1:10 What about the bypass? What about the bypass? A maintenance bypass means the load runs on unconditioned utility power, with no battery backup. And the manual is explicit: the UPS should not be operated with the cabinet doors open or protective panels removed.
1:25 What should you keep between visits? What should you keep between visits? The EVENTS screen: active alarms, notices, commands and a historical log. Photograph the logs before any reset; the order of events is the diagnosis.
1:38 What are the call signs? What are the call signs? The manual's rule: call if an alarm lamp is lit or the Online indicator is not lit. The lamp set also gives you red for an active alarm and yellow for battery or bypass.

Specifications
Efficiency, footprint & paralleling
Double-conversion efficiency on the Power Xpert 9395 is above 94%, rising to 99% with Energy Saver System. Eaton rates it the smallest footprint and lowest weight in its class, “50 to 60 percent less than competitive units”; an 825 kVA N+1 system is about 39 sq ft against a competitor’s ~125 sq ft. Input current distortion stays under 3.5% with no input filter (which eases generator sizing), and it carries leading power-factor loads to 0.9 without de-rating. Powerware Hot Sync wireless paralleling scales to 4 distributed modules, or 32 through the System Bypass Module, with load-sharing held under 3% and no system-level single point of failure; at or below 50% load the power modules behave as N+1 without a second UPS. An Easy Capacity Test stresses the full power train at full load with no external load bank.
In the field
Hurricane Electric deployed a pair of 550 kVA Power Xpert 9395 units with ESS in its 208,000 sq ft Fremont 2 data centre. Eaton's case study reports that the 9395 with ESS exceeded all expectations, providing the highest uptime and efficiency at the lowest possible cost, and the operator names efficiency and total cost of ownership as the deciding factors. After about three years the operator bought ten more 9395 units. We supply, install and maintain the 9395 the same way, on a service plan if you want one.
