•Ground the unit: The unit contains parts that may
be damaged by static discharge. A proper earth
ground connected to the lower left grounding screw
(see page 15 for more information) will significantly
reduce the chances of damage or improper
operation. The shielding in the cables specified for all
remote sensors and controls should also be
connected to the earth ground at the unit’s cabinet
end of the cable only. Damage caused by static
discharge is not covered by warranty.
•Use a dedicated power source: The outlet(s) you
plug the Chamberlain provided transformer or a DC
power supply should each be wired to their own
circuit breaker. The optional CCTV must be plugged
into a separate outlet. This will reduce line noise
introduced into system power and minimize the risk
of having other equipment interrupt unit operation.
Each unit and any door strikes must have their own
individual transformer.
•Do not overload the terminal blocks: Stranded
wire MUST be between 16 and 24 AWG. Solid wire
MUST be 18-24 AWG. If two wires are being used in
one terminal block, the thickness MUST fall within
these ranges. NEVER try to insert more than two
wires per terminal.
•Ensure good connections: A light tug on the wire
will tell you if the connection is secure.
•Read the markings carefully: Before making any
connections, be sure to read the markings and check
it against the corresponding figure in these
instructions for enhanced clarity.
