Chapter 2: Basic connections
IMPORTANT: Make sure to connect same identifications together and use the same network from
one side to the other.
IMPORTANT: The communication network must be installed in a daisy chain topology. Consult the
wiring diagrams to see the maximum cable distance according to the wire gauge.
NOTICE
The recommended installation is 16 AWG for the power supply wires at a length
of 300 meters (1000 feet). The recommended installation is 18 AWG for the
communication wires at a length of 1200 meters (4000 feet). The cable must be
twisted pair and shielded.
NOTICE
For the small terminal blocks used for inputs and low voltage outputs, use a
tightening torque from 0.5N*m (4.43lbf*in) to 0.6 N*m (5.2lbf*in) to fasten a wire.
The communication network must be installed in a daisy chain topology. The order of the wires is
very important. At both ends of network, the End-of-Line must be activated. If the wiring can’t be
done in a single chain, you might need to deactivate the end-of-line (EOL) resistor to improve com-
munication. AP/Cumberland does not warranty the proper operation if the topology network is not
daisy chain.
