Step 7 Earth Ground Rod; Step 8 Power Wiring - Chamberlain RSW12UL 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 (.9 m) 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.
The operator can be wired for either 120 Vac or a solar panel (not provided). Follow the directions according to your application. The battery is
charged in the circuit by the integrated transformer. The operator requires one 7AH battery (provided) or one 33AH battery. The 33AH application
requires the 33AH wire harness (Model K94-37236).
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.
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.
SOLAR APPLICATIONS: For solar applications refer to Solar Panels section in the Appendix. Follow the directions according to your application.
