INSTALLATION

INSTALLING THE EMERGENCY BALLAST
STEP #1
> Disconnect AC power from the fixture. Remove the ballast channel cover and install the emergency ballast
either in the ballast channel or on top of the fixture.* Remote mounting distance must be less than half the
maximum remote mounting distance for the AC ballast. Consult AC ballast manufacturer before remote
installation.
> Depending on the type of fixture in use install emergency ballast using one of the methods illustrated below.

* For installation on top of the fixture, wire bundle covers (RMC-60) may be required by state or local codes. These covers are
available from the manufacturer as an accessory kit and must be ordered separately. Call your local distributor or the factory for complete
information.
STEP #2
INSTALLING THE TEST SWITCH
> Refer to the illustrations above and install the test switch
through the ballast channel cover of a troffer or through the
side of a strip fixture.
> Drill a 1/2" hole and install the switch as shown.
> Wire the test switch so that it removes AC power from both
the emergency ballast and the AC ballast at the same time.
(see wiring diagrams)
INSTALLING THE CHARGING INDICATOR LIGHT
STEP #3
> Install the CHARGING INDICATOR LIGHT as shown in the illustration on the following page so that it will be
visible after the fixture is installed.
WARNING: TO PREVENT HIGH VOLTAGE FROM BEING PRESENT ON RED & YELLOW OUTPUT
LEADS PRIOR TO INSTALLATION, INVERTER CONNECTOR MUST BE OPEN. DO NOT JOIN
INVERTER CONNECTOR UNTIL INSTALLATION IS COMPLETE AND AC POWER IS SUPPLIED TO
THE EMERGENCY BALLAST.
NOTE:
Make sure the necessary branch circuit wiring is available. An unswitched source of
power is required. The emergency ballast must be fed from the same branch circuit
as the AC ballast.
