The CGCM-DLR unit connections are dependent on the application and
excitation scheme. All inputs or outputs cannot be used in a given installation.
Incorrect wiring can result in damage to the unit.
Connect the CGCM-DLR unit terminals with copper wire rated for a minimum
of 600V. General appliance wire that is rated for minimum temperatures of
105 °C (221
that are based on good design practice.
The wire gauge range that is listed in the
indicates the physical capabilities of the connector.
The CGCM-DLR unit terminals are on the front, bottom, and right panel of the
unit. The nine-pin connector on the bottom of the unit is used for
communication between CGCM-DLR units in a redundant system. Suggested
torque for terminal screws is 1 N•m (9 lb•in).

Terminals to be used as landing points for shielded wires are provided on several
terminal strips. Shield terminals with the same name are internally connected
together but are not connected to protective earth or any internal unit circuitry.
