EARTHING THE CABINET
Before wiring any internal components of the cabinet please ensure that the mains power supply to the
cabinet is switched OFF. The wiring of the internal components can be made following the technical wiring
diagrams that are supplied with the system. Once all connections are made and checked within the cabinet
and the connections from the cabinet to any external component (e.g. door intercom panels, audiophones
and videophones etc.) have been made then the mains power can be switched back ON.

The earth connection on the cabinet’s inline fuseholder should be connected to the earth stud on the cabinets
base plate and then linked across to the earth stud on the cabinet’s lid using the earth straps provided. The
earth connection on the building can then be connected to either the earth stud on the cabinet’s base plate
