Connecting Shielded (Environment-resistive) Cables
Wiring the Communications Power Supply
Note
Note
Check that the connector (plug or socket) on the Shielded T-branch Connector
or Environment-resistive Slave is the opposite of the connector (socket or
plug) on the Cable, align the connectors, and insert the cable connector.
Insert the connector fully and tighten the connector by hand. Tighten Micro-
size Connectors to a torque of between 0.39 and 0.49 N ⋅ m. Tighten Mini-size
Connectors to a torque of between 0.7 and 0.8 N ⋅ m.
There are three ways to wire the communications power supply. The following
table shows applications where each method can be used.
