NOTE 1
The Customer must provide input over current protection.
See National Electric
Code or local code requirements.
NOTE 2
The UPS bypass switch must be installed within sight of the UPS.
NOTE 3
The customer must size the AC circuit conductors.
All AC circuit conductors,
including the neutral conductors, must be the same size ( ampacity ), have the same
rating (75°C) copper wire, and be sized according to the input circuit breaker. The UPS
input and output conductors must be run through separate conduits.
NOTE 4
The Customer must provide output overcurrent protection.
See National Electric
Code or local code requirements.
NOTE 5
See “Equipment Clearances” for installation and service clearances before installing the
UPS. Use flexible conduit on the UPS or the external battery cabinet if either must be
removed.
NOTE 6
External battery cabinets are optional. See “Battery Cabinet Installation” for installation
instructions.
NOTE 7
UPS output circuits shall be installed in dedicated conduit systems and not shared with
other electrical circuits.
NOTE 8
Use only Eaton - supplied power cables between the UPS and battery cabinet.
NOTE 9
The customer must provide and install this ground connection according to NEC or local
code requirements. This grounding electrode conductor must be at least #8 AWG (8.36
mm). If the UPS input circuit conductors are larger than #8 AWG (8.36 mm), Eaton
requires the grounding electrode conductor to be the same size ( ampacity ) as the
largest UPS input circuit conductor. Conduit is not considered an acceptable grounding
electrode conductor. Eaton does not recommend routing the grounding electrode
conductor through metallic conduit. This conductor may require protection from physical
damage according to local requirements.

IMPORTANT
FOR U.S. INSTALLATIONS, READ THIS IMPORTANT NOTE
•
The mm² and AWG wire size for each circuit breaker size shown on the wiring diagrams. The minimum
recommended circuit breaker sizes for each model and voltage application are listed on the wiring
diagrams.
•
Conductor sizes shall be no smaller that the 75°C wire size . All circuit conductors, including the neutral
conductor, must be the same size ( ampacity ) wire. Code may require a larger AWG size than shown in
this table because of temperatures, number of conductors in the conduit, or long service runs. Follow local
code requirements.
