Installation & Setup Guide
Cable Connections
Move the Mode selector knob on top of the required
actuator to the ‘STOP’ position. This will inhibit
electrical operation.
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 fuse 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.
The actuator must be protected with an over current
protection device rated in accordance with publication No.
P110E, which details the electric motor performance data for
CVA range actuators.
Earth Ground Connections
An internal earthing point is provided for water tight
applications. In addition a mandatory 6mm external earthing
stud is provided for all explosion proof applications.
Removing Terminal cover
Using an 8mm 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.
Remove the power terminal insulated cover and connect
temporary or site wiring in accordance with the supplied
wiring diagram.
Note: The Red (Power) and (Control) terminal
protective covers should be replaced prior to refitting
of the electrical cover assembly.
When the actuator is supplied with an Intrinsically
Safe terminal compartment, the unit is supplied with
a Red and Blue terminal cover. The Blue terminal cover
identifies the IS Circuit connections. Covers must be
fitted to maintain certification.
