SAFETY PRECAUTIONS
CAUTION!
Input and Output circuit breakers must be “OFF” during the building installation.
CAUTION!
An additional two pole disconnect device is necessary during the building installation.
CAUTION!
Disconnected EPO will immediately shut down the logic circuit output of the UPS. Wiring the EPO signal is optional.
CAUTION!
Local safety rules may require a separate, external EPO to turn off output circuit breakers. Refer to local wiring rules, the EPO should use
approved components.
