2.3 WIRING CONNECTIONS
External connections are by 27 screw terminals as follows:
Screw terminals are 7.5mm and 5mm spacing rising clamp style with 2.5mm²
wire entry size for power connections and with 1.5mm² wire entry size for
signal connections.
The terminal identification and description are provided below, together with
the maximum terminal capacity in mm
2
(shown in brackets). Note that some
terminals may require more than one cable to be terminated, and therefore
cable sizing should be selected accordingly. The 12V dc and 0V dc terminals
may require several cables to be terminated in a separate connector,
according to the number of remote sensors required. Any series wiring for
occupancy or switch sensor inputs should be achieved using a separate
connector.
