Wiring Of Control Board - LiftMaster CB202EV Manual De Instrucciones

WIRING OF CONTROL BOARD

The cables for the power supply and the connected equipment are
routed from below into the sliding door operator through the rubber
seal at the bottom of the control board covering.
The control board is to be mounted with the terminal strips down
as shown in the picture A.
Generally avoid:
- 230Volt and low voltage in the same power line. Not allowed by
electrical rules.
- Wiring of the photocells, switches, fl ashing lamps require a cable
separately from the motor wiring.
- Other wirings like telephone intercoms, lights for garden etc. must
be in separate cables.
- Rigid copper cables especially when thicker diameters are diffi cult
to manage during the installation and may result in bad
connections with functional issues. Use fl exible cables instead.
- Cable material not suitable for outside use. Use cables suitable for
outside use and underground. Run the cables in conduits if the
cable is not suitable for placing in the ground (armoured or suitably
protected). You may also consult your local electrician.
Terminals:
The terminal blocks on the controller can be removed (pull) to
facilitate a convenient wiring and are pushed back only while
installing the controller. Even if a terminal strip is not in use, it must
be pushed back. The wiring is done as described in the wiring
diagram.
Plugs (available on the motor and the transformer):
These plugs must be connected to the control board (plugged in).
The cable of the connectors are not routed from below, but from the
back of the control board (see picture B).
