Wiring
Disconnect AC mains power from the controller before performing
wiring.
Connections to the control unit are made through the wiring card (see
Figure 3-16). For the general purpose rack and panel mount versions, the
wiring card is located on the rear of the control unit. The wiring card is lo-
cated on the front bottom of the control unit for all weatherproof versions
and for the general purpose wall mount version. Figure 3-16 shows the
orientation of the wiring card for general purpose rack and panel mount
versions - for all other versions, the wiring card is rotated 180 degrees.
To access the wiring card for all general-purpose control unit versions,
unscrew the four screws on the wiring card chassis cover plate. For the
weatherproof versions of the control unit, you will first need to open the
front door of the weatherproof enclosure to gain access to the wiring card
shield. Remove the three screws on this shield to gain access to the wiring
card.
