8 AFDK-SVU01C-EN
Drive and Cabinet
Enclosure Rating
The Trane
®
cabinet has a NEMA 1 enclosure rating:
NEMA 1: Vented. Intended for general-purpose indoor
applica
tions.
Environmental Conditions
Important: Location of the AFDK is important if proper
performance and normal operating life is to
be expected. Therefore, unless designed for
special environments, the controller should
be installed in an area where the following
conditions exist.
• Verify that NEMA 1 enclosure is installed where it can
be kept clean an
d dry, away from oil, coolants, or other
airborne contaminants. The enclosure must be
installed in a non-corrosive location.
• The area chosen should allow the space required for
proper air flow. Adequate clearance for air circulation
around the enclosure is a 6 inch (15.25 cm) minimum
clearan
ce required wherever vents are located in the
cabinet.
• The area chosen should allow for service clearance in
front of the enclosure. Three feet (0.91 m) is
recommended for door swing and working space;
more space may be required by local building codes or
for service equipment, such as hoists used for drive
replacement. Because codes and equipment may vary,
determine the amount of space required for each
specific installation.
• Do not install the drive over 1000 meters (3300 feet)
above se
a level without derating output power. For
every 91.4 meters (300 feet) over 1000 meters
(3300 feet)
above sea level, derate the output current
1 percent.
• Line frequency is 60 Hz.
• Line voltage is 460 or 480 volts; variation must be
within
+10 percent.
• Verify that the drive location will meet the
environmen
tal conditions specified in Table 1.
