Connecting the ac Input Supply
The equipment is permanently connected to the mains supply when the mains connectors
are attached. Switching the rear panel Power switch to Standby does not isolate all internal
circuits from the mains supply. For this reason, a mains isolating switch should be fitted
close to, and easily accessible from, the controller’s position. The isolation switch should
isolate both live and neutral supplies to the IEC connector fitted to the controller, be clearly
labelled, and adequately rated to protect the equipment.
The mains ac supply must be connected to the controller using the supply connector provided ( Table 4-2 ,
item 3 ). Before connecting the ac supply to the controller, ensure the mains selector on the rear panel is
correctly set to suit the ac supply being used:

Between 110 Vac and 120 Vac the selector must be set to 110

Between 220 Vac and 240 Vac the selector must be set to 220.
The T6MC controller is a class 1 equipment. The ac supply cable must have a green-and-yellow
protective earthing conductor electrically connected to the protective earthing terminal of the equipment
connector and the supply output connector. The ac supply cable should be colour coded in accordance
with the electrical appliance (colour code) regulations for the UK. That is:
Live: Brown
Neutral: Blue
Earth: Green-and-yellow.
Connections are shown in Fig 4-2 . After connection has been made, ensure the connector retaining clip
is fitted.
