UPS Installation Plan and Unpacking
•
To allow for a future upgrade, install a three UPM model using conductors and external overcurrent
protection breakers sized the same as a fully rated 1200 kVA model.
•
For external wiring, use 75 ºC copper or aluminum wire. Wire sizes listed in tables
for copper wiring only. If wire is run in an ambient temperature greater than 30 ºC, higher temperature wire
and/or larger size wire may be necessary. Wire sizes are based on using the specified breakers.
•
Wire ampacities are chosen from Table 310-16 of the National Electrical Code
copper wire with a 75 ºC rating.
•
Material and labor for external wiring requirements are to be provided by designated personnel.
•
If installing a maintenance bypass, a minimum of two separate feeds with upstream feeder breakers, or a
single feed with two upstream feeder breakers, must be provided: one for the UPS or rectifier input
breaker (RIB) (if installed) and one for the maintenance bypass input. DO NOT use a single feed or a single
feeder breaker to supply both the UPS or RIB and the maintenance bypass. If a bypass input breaker (BIB)
is installed in the maintenance bypass and a single-feed UPS is being installed, a single feed to the
maintenance bypass is acceptable for supplying both the UPS and the bypass.
•
The bypass and rectifier feeds into this equipment use three wires for the 480V, and four wires for Bypass
for the 415/400/385V models. The phases must be symmetrical about ground (from a Wye source) for
proper equipment operation.
•
The Eaton 9395P-1200 480V unit is designed for operation on a grounded-wye source of supply. There is
no additional connection point for a neutral conductor. The output of this UPS will not directly support
phase to neutral loads.
•
The ISBM and UPM sections are shipped with debris shields covering the ventilation grills on top of the
sections. Do not remove the debris shields until installation is complete. However, remove the shields
before operating the UPS. Once the debris shields are removed, do not place objects on the ventilation
grills.
•
In a common battery system, all UPMs are powered from one common battery source. In a separate
battery system, each UPM is powered from separate battery sources.
•
UPSs in distributed bypass and parallel systems must use a separate battery system for each UPS.
•
On a UPS configured as an Input Output Module (IOM), requirements for bypass input wiring, termination,
conduit, and bypass breaker are not applicable.
•
A Field Installed UPM (FI-UPM) is always designated as UPM 4.
If the power rating listed on the nameplate of the installed UPS is not found in the following tables, wire the
UPS using the fully rated specifications. Otherwise, calculate the required wire, conduit, and breaker sizes
using the following guidelines in addition to those already listed in paragraph
3.2.4 UPS System Power Wiring
•
Select wire size according to the UPS nameplate.
•
Do not use wire larger than the largest size listed in tables
•
Use terminal recommendations from
•
Size and number of conduits must not exceed those listed in
•
Select overcurrent protection input, battery, and output breakers according to the UPS nameplate rated for
either 80% or 100%.
•
Follow all applicable NEC and local codes.
For four UPM external wiring requirements, including the minimum AWG size of external wiring, see
for installations using a common battery system or
Wire sizes listed are for copper wiring only.
