Cable Routing and Connection
9. Connect the Control Modules to the
CAN (Controller Area Network)
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, and
electric shock all wiring must be done by
a qualified electrician.
The cables are connected at each control module by
stripping the wires and connecting the wires as shown
in Fig. 10. Refer to Fig. 9 for the placement of the
control module connectors.
Each control module ships with a terminating resistor
on the connector for the CAN network. When the cable
is connected to the control module, the resistor must
be removed from the control modules located in the
middle of the network chain, leaving only the resistors
at each end of the network. The end resistors are
necessary for the control modules to be able to com-
municate properly with each other across the network.
Connect the control module(s) in the middle of the
network chain as shown in Fig. 10, with the termi-
nating resistor removed.
Connect the control modules at the end of the
network chain as shown in Fig. 10, with the termi-
nating resistor in place.
Controller Area Network (4 control modules shown)
Use Bulk Cable P/N 113–559 (500 ft. [152.5 m]) or 113–560 (1000 ft. [305 m)])
NOTE: No distance requirement between control modules provided the overall length of the network cables does not exceed 2000 ft. (610 m).
