Wiring; Step 6 Power Wiring - LiftMaster Elite Serie Manuel D'installation

To reduce the risk of SEVERE INJURY or DEATH:
ANY maintenance to the operator or in the area near the operator
l
MUST NOT be performed until disconnecting the electrical power (AC
or solar and battery) and locking-out the power via the operator power
switch. Upon completion of maintenance the area MUST be cleared
and secured, at that time the unit may be returned to service.
Disconnect power at the fuse box BEFORE proceeding. Operator
l
MUST be properly grounded and connected in accordance with
national and local electrical codes. NOTE: The operator should be on a
separate fused line of adequate capacity.

Step 6 Power Wiring

All control wiring used to connect external devices to Class 2 circuits of the
operator must be (QPTZ) Power-Limited Circuit Cables, Type CL2, CL2P, CL2R,
or CL2X or other cable with equivalent or better electrical, mechanical, and
flammability ratings.
NOTE: The operator can also be powered by solar panels, refer to the dealer
extranet on LiftMaster.com for more information.
Proper grounding gives an electrical charge, such as from an electrical static
discharge or a near lightning strike, a path from which to dissipate its energy
safely into the earth. The ground wire MUST be a single, whole piece of wire.
NEVER splice two wires for the ground wire. If you should cut the ground wire too
short, break it, or destroy its integrity, replace it with a single wire length. Use the
proper type earth ground rod for your local area. In certain circumstances, metal
water pipes may be allowed for grounding the operator. Check and follow all local
codes for proper grounding procedures.
1. Turn off the AC power from the main power source circuit breaker.
2. Run the AC power wires to the operator.
3. Loosen the nut on the cover of the EMI board and slide the cover back.
4. Connect the green wire to the ground wire using a wire nut.
5. Connect the white wire to NEUTRAL using a wire nut.
6. Connect the black wire to HOT using a wire nut.
7. Ensure the power wiring connector is connected to either the 120 or 240 Vac
socket depending on the application. Factory default is 120 Vac.
8. Slide the EMI cover back and tighten nut.
9. Connect the batteries then turn on the AC power. Connect the J15 plug to the
control board.
NOTE: The AC Power switch on the operator will turn the incoming 120/240 Vac power ON or OFF. The operator's AC Power switch ONLY turns off AC
power to the control board and DOES NOT turn off battery power.
Minimum 12 Gauge Ground Wire

WIRING

ALL electrical connections MUST be made by a qualified individual.
l
DO NOT install ANY wiring or attempt to run the operator without
l
consulting the wiring diagram.
ALL power wiring should be on a dedicated circuit and well protected.
l
The location of the power disconnect should be visible and clearly
labeled.
ALL power and control wiring MUST be run in separate conduit.
