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 AFDE 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. 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.
•
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 300 feet
(91.4 meters) above 3300 feet (1000 meters), derate
the output current 1%.
•
Line frequency is 50 or 60 Hz.
•
Line Voltage is 380–480 volts; variation are within
+10%.
•
Non-corrosive location.
•
Verify that the drive location will meet the
environmental conditions specified in Table 1.

Components
Trane AFDE cabinets have the following main
components. For convenience, the drive is discussed in
two sections, a rectifier (input) and inverter (output)
sections. See
