6. Supply Wiring
The LC1000-100/LC1500-100 controller is powered by -48VDC from the shelter. A field-supplied 5 amp DC circuit
breaker is required. Field-supplied supply wiring should be minimum 16 guage, maximum 14 guage (see Figure
1.25). A reliable earth ground must be connected in addition to any grounding from conduit. Grounding posts are
included with the controller for this purpose; install as shown in Figure 1.26. Failing to ground the controller box
properly could result in damage to the equipment.

-48VDC termination at controller: Bring the -48VDC power supply wires
through conduit to the controller box. Land the positive (+) 48VDC wire
to terminal #1 and the negative (-) 48VDC wire to terminal #2.
NOTE: If the DC wiring is not terminated correctly on the
specific polarity-indicated terminals of the PLC block, the
PLC controller will not activate and will not function. Verify
polarity of connections and wait to initialize controller until
"startup procedures."
