electrical Installation
wARnIng
ensure all power supplies are isolated before removing
actuator covers.
Check that the supply voltage agrees with that stamped on
the actuator nameplate. A fused switch or circuit breaker
must be included in the wiring installation of the actuator. The
switch or circuit breaker must be installed as close as possible
to the actuator and shall be marked to indicate that it is the
disconnecting device for that particular actuator. Actuator
must be mounted such that it is not difficult to operate the
disconnecting device.
The actuator must be protected with an over current
protection device rated in accordance with PUB094-001
which details the electric motor performance data for CMA
range actuators.
earth ground Connections
A lug is cast adjacent to the conduit entries for attachment of
an external protective Earth (Ground) cable. An internal earth
terminal is also provided. However it must not be used alone
as the protective Earth Connection. See Fig. 24.1.
Removing Terminal cover
Using a 6 mm Allen key loosen the captive fixings securing the
terminal compartment cover. Do not attempt to lever off the
cover with a screwdriver as this will damage the O-ring seal
and may damage the flamepath on a certified unit.
If necessary locate the two set screws Fig. 24.2 and use them
to lift the cover away from its seat.
