Drive and Cabinet
Enclosure Rating
The Trane® cabinet has a NEMA 1 enclosure rating:
NEMA 1: Vented. Intended for general-purpose indoor
applications.
Environmental Conditions
Important:
Location of the AFDG/AFDU 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 drives can be kept clean
and dry.
•
The area chosen should allow the space required for
proper air flow. An 8 inch (20.32 cm) minimum
clearance is required above the cabinet.
•
Be sure that the NEMA 1 enclosure is installed away
from oil, coolants, or other airborne contaminants.
•
Do not install the drive above 3300 feet (1000 meters)
without derating output power. For every 3300 feet
(1000 meters) above 3300 feet (1000 meters), derate
the output current 4%.
•
Line frequency is 60 Hz.
•
Line Voltage is 460/480/575 volts; variation are within
+10%.
•
Non-corrosive location.
•
Verify that the drive location will meet the
environmental conditions specified in Table 1.
