Read and understand the following notes while planning and performing the installation:
•
Refer to national and local electrical codes for acceptable external wiring practices.
•
To allow for future kVA upgrades, consider installing a derated UPS using wiring and external overcurrent
protection breakers sized for a fully rated UPS.
•
•
For external wiring, use 75°C copper or aluminum wire. Wire sizes listed in
are for copper wiring
only. If wire is run in an ambient temperature greater than 30°C, 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 310.15(b) (16) of the National Electrical Code
®
(NEC
®
).
Specification is for copper wire with a 75°C 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. The phases must be symmetrical
about ground (from a Wye source) for proper equipment operation.
•
The Eaton 9395C 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 a debris shield covering the ventilation grill on top of the
unit. Do not remove the debris shield until installation is complete. However, remove the shield before
operating the UPS. Once the debris shield is removed, do not place objects on the ventilation grill.
•
UPs in distributed bypass and parallel systems must use a separate battery system for each UPS.
