2.2 Installing into a Rack Enclosure
When mounting the CDM‐750 into a rack enclosure (Figure 2‐2):
• PROPER GROUNDING PROTECTION IS REQUIRED. The equipment must be
connected to the protective earth connection at all times. It is therefore imperative
that the unit is properly grounded, using the ground stud provided on the unit rear
panel, during installation, configuration, and operation.
• PROPER AIR VENTILATION IS REQUIRED. In a rack system where there is high
heat discharge, provide forced‐air cooling with top‐ or bottom‐mounted fans or
blowers.
o Make sure there is adequate clearance inside the enclosure, especially at
the side for air ventilation.
o Air temperature inside the rack enclosure should never exceed 50
°
C
(122
°
F).
