Earth Ground Rod; Power Wiring - Chamberlain CSW24U Installation Manual

STEP 7

EARTH GROUND ROD

Use the proper earth ground rod for your local area. 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.
1. Install the earth ground rod within 3 feet of the operator.
2. Run wire from the earth ground rod to the operator.
NOTE: If the operator is not grounded properly the range of the remote
controls will be reduced and the operator will be more susceptible to
lightning and surge damage.
STEP 8

POWER WIRING

To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the operator
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
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.
This operator can be wired for either 120 Vac or 240 Vac or a solar panel (not provided). Follow the directions according to your application.
For dual gate applications, power will have to be connected to each operator. Main power supply and control wiring MUST be run in separate
conduits.
SOLAR APPLICATIONS: For solar applications refer to Solar Panels section in the Appendix. Follow the directions according to your application.
NOTE: If using an external receiver use shielded wire for the connections and mount the receiver away from the operator to avoid interference with the
operator.
