a. Unplug EACH UNIT
b. Plug the COMMUNICATION CARD IN the UNIT
Open the cover. Drill a 5/16" hole through the bottom of the controller and thread the
communication cable through the hole. Use the grommet provided to secure the
cable. Connect the cable to the terminals of the communication card as shown
below. When connecting two cable ends together, solder the joint and use a heat
shrink to ensure a proper contact.
Line-up the module with the connector and insert it in the upright position (see photo
below). For communication, always use a 1 twisted pair shielded cable. The maximum
length of the cable is 3000m (10,000 ft) and the recommended wire diameter is
1.0mm (18 AWG). Use a lightning protection module when running the cable between
buildings.
Be sure the communication cable is isolated from all high voltage sources and
fluorescent lights. Do not route the communication cable and power cables
!
through the same electrical knockout. Do not run the communication cable
next to power cables. When crossing power cables, cross at 90°.
