3.3 Cooling
•
Only mount the drive and panel vertically.
•
Panels rely on the ambient air for cooling. It is
important to observe the limitations on ambient

air temperature. The maximum ambient
temperature for all bypass panels is 40°C and
45°C for non bypass panels. Derating concerns
start above 3300 feet elevation above sea level.
•
Most panels may be mounted side-by-side
without additional side clearance. However, the
P2 (B3 frame size) units require 1.5 in. minimum
clearance between units (see Figure 3.2).
•
Top and bottom clearance is required for cooling
(see Figure 3.3). Generally, 2 to 10 inches (50 to
250mm) minimum clearance is required,
depending upon the hp (kW) of the unit. See the
dimensional drawings in 8 Appendix for specific
requirements.
•
No additional back plate is required for drives
with the bypass and non bypass panels.
