Installation
Mounting Requirements This equipment is intended for use in a Pollution Degree 2 Industrial
Environment, in over-voltage 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, possibly leading 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 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 Unit Overall Dimensions
on page 14 .
WARNING:

• Do not replace components or disconnect equipment unless power has been switched
off or the area is known to be non-hazardous.
• Do not connect or disconnect components unless power has been switched off or the
area is known to be non-hazardous.
•
This product must be installed in an enclosure. All cables connected to the product
