All electrical connections are made to the screw terminals at the rear of the controller. If

you wish to use crimp connectors, the correct size is AMP part number 349262-1. They

accept wire sizes from 0.5 to 1.5 mm2 (16 to 22 AWG). A set of connectors is supplied with

the controller. The terminals are protected by a clear plastic hinged cover to prevent hands,

or metal, making accidental contact with live wires.

Rear terminal layouts

The rear terminal layouts are shown in Figure 1-6. The right-hand column carries the

connections to the power supply, digital inputs 1 and 2, alarm relay and sensor input. The

second and third columns from the right carry the connections to the plug-in modules. The

connections depend upon the type of module installed, if any. To determine which plug-in

modules are fitted, refer to the ordering code and wiring data on the controller side labels.
