Read and understand the following notes while planning and performing the installation:
WARNING
As a result of the connected loads high leakage current is possible. Connection to earth ground is required for
safety and proper product operation. Do not check UPS operation by any action that includes removal of the
earth (ground) connection with loads attached.
•
Refer to national and local electrical codes for acceptable external wiring practices.
•
To allow for future power upgrades, Eaton recommends installing the UPS using wiring and external
overcurrent protection breakers sized for the fully rated UPS kW frame size instead of the derated kW
ordered. Wiring for the maximum kW frame size will allow a full power rating upgrade without having to
modify the site wiring infrastructure.
•
For external wiring, use 75°C copper wire.
!
IMPORTANT
This product has been evaluated for use with
copper wire
only
. For external wiring, use only 75°C copper wire.
Wire sizes listed in
through are for copper wiring only. If wire is run in an ambient temperature
greater than 40°C, larger size wire may be necessary. Wire sizes are based on using the specified
breakers.
•
The AC output and output ground wiring to the critical load should be sized the same as the UPS rectifier,
bypass, and rectifier and bypass ground wiring if the recommended output breaker listed in
is not
installed in the system.
