3.2.5 Cooling

•
Mount the drive and panel vertically.
•
Option panels rely on the ambient air for cooling,
it is important to observe the limitations on
ambient air temperature. See Table 3.2 for
temperature rating data. Derating concerns start
above 3300 feet elevation above sea level.
•
Most option panels with drives may be mounted
side-by-side without additional side clearance. A2
and A3 units require 1.5 in. clearance between
units (see Illustration 3.4).
•
Top and bottom clearance is required for cooling
(see Illustration 3.5). Generally, 100 to 250 mm (4
to 10 inches) minimum clearance is required,
depending upon the hp (kW) of the unit. See the
mechanical drawing shipped with the unit for
specific requirements.
•
No additional back plate is required for drives
with the option panel.
•
Units may be mounted flush to the wall or free
standing. A free-standing mounting kit is
available from Danfoss.
•
See Table 3.2 for temperature ratings.
