In order to install the EPC in accordance with national/local code requirements, a qualified electrician
should review & understand the installation instructions. Check voltage & current requirements.
Verify & lock out circuit breakers on both regular (utility) power & 24 hour emergency generator or
inverter circuit. Install a self-adhesive 2" x 3" caution label in each fixture or load controlled by an EPC
cautioning that the load is supplied from 2 different power sources, normal & emergency. Review
wiring diagram & connect wires, one at a time, in accordance with the numeric identification.

Turn on Normal/Emergency power sources.
Initial Testing
In order to test that the wires are connected correctly, without any inconvenience to occupants, do
not turn off regular (utility) power off until you have checked each device as follows:
1) Check that regular branch circuit breaker is connected & utility power is available. Green LED on
If green LED is not lit, check connections & continuity to branch circuit breaker. If using 3 phase
sense mode, ensure power is applied to all 3 phases. If using 1 phase only, connect Orange Brown
Yellow wires together.
