Installation
Mounting Requirements
This equipment is intended for use in a Pollution Degree 2 Industrial
Environment, in overvoltage Category II applications (as defined by IEC
publication 60664-1). Because the units contain a heat sink, they must be
mounted vertically. Any other mounting angle reduces the heat dissipation
capabilities of the units, which can lead to premature failure of critical
components. The unit can be mounted anywhere that the ambient temperature
does not exceed the rated environmental conditions or clearance requirements.
The clearance requirements for the CGCM-DLR unit are:
•63.5 mm (2.5 in.) of clearance is required on both sides of the unit when
mounted.
•101.6 mm (4 in.) of clearance is required above and below the unit when
mounted.
Overall dimensions for the unit are shown in CGCM-DLR Unit Overall
Dimensions on page 16.
WARNING: Explosion Hazard
•Substitution of components can impair suitability for Class I, Division 2.
•Do not replace components or disconnect equipment unless power has been switched
off or the area is known to be nonhazardous.
•Do not connect or disconnect components unless power has been switched off or the
area is known to be nonhazardous.
•This product must be installed in an enclosure. All cables that are connected to the
product must remain in the enclosure or be protected by conduit or other means.
•All wiring must comply with N.E.C. article 501-4(b).

Installation Chapter 2
Electrical Connections
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 °F) is acceptable. All wire must be copper. Select circuit conductors
that are based on good design practice.
The wire gauge range that is listed in the Terminal Block Label Description table
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).
See pages 19…36 for typical connection diagrams.
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.

Excitation Power
Excitation power is wired to the PMG terminals, whether connected to the
generator output (Shunt Excited) or to a PMG. Connect shunt excited inputs
with a voltage transformer (VT).
PMG inputs are on TB1 and are labeled PMG A, PMG B, and PMG C, to
illustrate their respective phase relationships. Single-phase excitation power must
be connected to terminals PMG A and PMG C. Twisted, shielded cabling is
required for the PMG inputs.
See these wiring diagrams for more information.
