4.2
Removing the AC Breaker/Terminal Block Cover
There is a single screw that holds the AC Breaker/Terminal Block Cover securely to the
chassis. This cover conceals the wiring area and provides a safety cover so that fingers
cannot inadvertently touch live parts after installation. After removing this screw, simply lift the
cover up all the way until it is perpendicular and slide it forward so that the two flanges on the
cover release from the mating two slots on the chassis.
WARNING – Always re-install the AC Breaker/Terminal Block Cover to prevent
accidental contact with live wires during routine maintenance.
4.3
Installing the Input Wires
Once the Top Cover and Circuit Breaker Terminal Block Cover are removed:
1. Ensure that the incoming AC voltage to the Lite-Minder is the same voltage rating as the
unit.
2. Ensure that the feed breaker from the panel has at least the same breaker rating as the Lite-
Minder’s input breaker.
Once Feed Voltage and Breaker size is correct, connect the Utilities Feed Line voltage to the
Input Circuit Breaker. There will also be a dedicated position for Neutral, and Ground. Ensure
that the connections are tight by giving the wires a good pull and ensure that the wires are
secured into the blocks. Connection to these blocks will require a small flat bladed screw-
driver.
NOTE – AC Input and AC output wires must be run in separate conduit or raceways per
NEC ARTICLE 700. Please ensure all codes and standards are observed.
NOTE - Lite-Minder requires that the Neutral and Ground potential does not exceed 5 VAC
for proper function. Anything above 5 VAC typically indicates that there may be a
grounding issue or inadequate conductor size or continuity. This should be looked at
immediately as it could cause a safety concern.
NOTE – Neutral and ground should never be tied together anywhere in the Lite-Minder.
Always keep Neutral and Ground wires separate and ensure no shorts occur.
NOTE – Neutral connections in Lite-Minder are a “Pass Through’ which means Input and
Output Neutrals are directly connected.
NOTE – Never mix Neutrals on the building wiring(Non-Emergency) with the Emergency
wiring. Dedicated wiring is required by NEC code ARTICLE 700.
4.4
Installing the Output Wires
Connect the load wires to the terminal block labeled N. On, N. Off or Switched Outputs. There
will be dedicated terminal hook up positions for each Line, Neutral and Ground similar to the
AC Input section. Again, ensure that the connections are tight by giving the wires a good pull
and ensure that the wires are secured into the blocks. Connection to these blocks will require a
small flat bladed screwdriver. In the event that an output circuit breaker was supplied in the
unit, the load hot wire will be directly connected to the breaker. Load Neutral and Ground will
still connect to a terminal block.
