shields before operating the UPS. Once the debris shields are removed, do not place objects on the
ventilation grills.
• UPSs or each UPS in distributed bypass and parallel systems must use a separate battery system for each
UPS.
The Eaton 9395XC UPS provides backfeed detection and protection through a UVR trip mechanism of the
bypass input breaker. An optional I/O Cabinet is also available with an integrated backfeed contactor.
The AC output and output ground wiring to the critical load should be sized the same as the UPS bypass and
bypass ground wiring if recommended output breaker listed in Table 13 is not installed in the system.
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 Preparation:
• Select wire size according to the UPS nameplate.
• Do not use wire larger than the largest size listed in Table 5.
• Use terminal recommendations from Table 11.
• Size and number of conduits must not exceed those listed in Table 11.
• 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 UPS external wiring requirements, including the minimum AWG size of external wiring, see Table 8 for
recommended installations using a common battery system. Wire sizes listed are for copper wiring only.
