Wiring the LZC1 in Bypass
Bypass wiring is a TEMPORARY wiring scheme to test
the dimming ballast wiring without using the LZC
control. If there is a wiring problem or a short in the
circuit, this will prevent damage to the LZC.
• The lighting zone controller accepts any 100 to 277
V
(50 or 60 Hz) line feed. The electronic fluorescent
ballasts, however, must be rated for the specific line
voltage that feeds the lighting zone controller.
• Make the appropriate wire connections for your ballast
type following the wiring diagram below.

Testing the Circuit in Bypass
• Turn the input power ON after assuring that it is safe
to do so. Lights should go to full ON while in bypass.
If lights do not go to full ON, check ballast and lamp
wiring.
• Once the ballast and lamp wiring are tested, turn the
input power back OFF at the supply breaker.
Danger! Check that all loads on the circuit
are safe to have power applied before turning
the input power ON.

Danger! Locate and lock the supply breaker
in the OFF position, or remove the supply
fuse before continuing.
Danger! Proper short-circuit and overload
protection must be provided at the
distribution panel. You can use a 20 A
maximum circuit breaker for your installation.
