4. Installation
• Ensure the mains supply is switched off and the circuit supply
fuses are removed or the circuit breaker turned off.
• Connect the incoming 230V 50Hz supply and outgoing load cables
to the relevant terminals ensuring correct polarity is observed
and that all bare conductors are sleeved (see section 5.
Connection Diagram).
• A front cable exit cut-out is provided with a pre-installed
removable cover.
• If the front exiting cable cut-out is required:
1. Undo the 2 fixing screws and remove the blanking plate
(you can discard the blanking plate at this stage but keep
the 2 fixing screws).
2. Remove the cable grip from the accessory pack.
3. Using the 2 fixing screws previously removed from
the blanking plate, secure the load cable to the unit.
• Finally secure the unit to the back box with the fixing
screws provided, forming the cables during installation
to avoid any entrapment and cable damage.
