6.13 Connecting the Mains Cabling
Isolate the incoming mains supply by ensuring the fused double pole isolator is in the
‘OFF’ position.
Pay particular attention that the incoming mains cable is segregated from all other
cables within the 6100 enclosure.
Ensure the incoming earth cable is firmly connected to the Main PCB ( see figure
6.11 ), and that the earth cable from the Main PCB is securely connected to the brass
earth terminals within the back-box.
The mains wiring must now be restrained using the clamp provided to secure the mains
cables to the control PCB housing ( see figure 6.12 ). The restraining clamp must be
supported at the rear when the two screws are being tightened.
