Environmental Conditions - Trane RTHD Installation Instructions Manual

Environmental Conditions

Important: The location of the AFDR 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 and 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
clearance 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 3300 ft (1000 m) above sea
level without derating output power. For every 300 ft
(91.4 m) over 3300 ft (1000 m) above sea level, derate the
output current 1 percent.
• Line frequency is 60 Hz.
• Line voltage options are 460, 480, 575 or 600 volts;
variation must be within +10 percent.
• Verify that the drive location will meet the environmental
conditions specified in Table
