LV1000 Supply Wiring
The LV1000 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 gauge, maximum 14 gauge (see Figure 27). 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 28. Failing to ground the controller box properly could result in
damage to the equipment.
The controller requires a separate -48VDC power supply, an additional 5-amp DC breaker (field supplied) and minimum 16
gauge supply wire.
-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
block, the controller will not activate and will not function. Verify polarity of connections and wait to
initialize controller until "system start up."

Controller Grounding Posts
A reliable earth ground must be connected in
addition to any grounding from conduit. Attach
earth ground to dedicated lugs on side of controller
box. Failing to ground the controller box properly
could result in damage to the equipment or
personal injury.
