5. Installation & Connection
• Ensure the mains supply is switched off and the circuit supply fuses
are removed or the circuit breaker turned off.
• An isolating switch should be installed to enable the power to be
switched ON & OFF for maintenance purposes and to activate the
manual/auto override function.
• Remove the wiring cover from the sensor by depressing the catch
on the side and lifting it clear of the twin locators opposite the
catch (See diagram “G”).
• Mark the position of the 75mm diameter fixing hole centre taking care
to avoid ceiling joists and other obstructions within the 75mm diameter.
• Using a pad saw or suitable hole cutter cut out a 75mm diameter hole
• Pass the 230V 50Hz mains supply and load cables through the hole
and prepare for termination.
• Terminate the cables into the terminal block ensuring correct polarity
is observed and that all bare conductors are sleeved (See below details
on connection);
