Eaton 9395XC UPS 1200kW/1200kVA, 1350kW/1350kVA or 1500kW/1500kVA 164001079—Rev 01

•
LAN drops for use with Minislot connectivity cards must be provided by the customer and may need to
use Class 1 wiring, see above.
•
The UPS battery aux signal wiring from the UPS must be connected to the battery disconnect device.
•
A supplemental 48 Vdc UVR signal for the battery disconnect device is provided, but is not required for
normal operation.
•
Battery aux and 48 Vdc UVR wiring should be a minimum of 18 AWG.
•
The REPO feature opens all contactors in the UPS cabinet and isolates power from your critical load. Local
electrical codes may also require tripping upstream protective devices to the UPS.
•
The REPO switch must be a latching-type switch not tied to any other circuits.
•
A jumper wire must be connected on the J89 MCU Board between pins 2 and 4 if the normally-closed
REPO contact is not used.
•
REPO wiring should be a minimum of 22 AWG and a maximum of 14 AWG.
•
The REPO switch wiring must be in accordance with NEC Article 725 Class 2 requirements.
•
The maximum distance between the REPO and the UPS cannot exceed 150 meters (500 feet).
•
Alarm relay contacts have a maximum current rating of 5A and a switched voltage rating of 30 Vac and 28
Vdc.
•
Alarm relay wiring should be a minimum of 22 AWG.
NOTE 1
On all 9395XC models that will be fed by a site generator at any time it is recommended
to have an “On Generator” sensing input connected and proven functional. This allows
the UPS to optimize its operation with the generator. This function includes reduced
input current and battery current limits, slower walk-in to ease the load step on the
generator initially, and HIGH ALERT mode for ESS operation.
NOTE 2
HIGH ALERT mode is desired because any loads with a leading power factor will not be
seen by the generator. Rectifier operation will be much softer while on generator
thereby increasing overall system stability.
Connectors for the control and interface wiring are supplied in the hardware kit are listed in
