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 wire. Wire sizes listed in Table 5 are for copper wiring only. If wire is
run in an ambient temperature greater than 40°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 and 40°C ambient correction factors.
• 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 9395XC 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 I/O Cabinet and ISBM/PM 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
