General; Clearances; Backplate Requirements - Trane TR1 6002 Installation And Operation Manual

General

The specific installation instructions may vary depending upon the
model of TR1 Series VFD being installed. When this occurs, the model
can be identified by a “TR1 Type 6XXX” number. This number can be
found on the red nameplate on the outside left side of the drive
enclosure, or the outside right side of a drive with an auxiliary
enclosure.
The drive must always be installed vertically. To ensure that no injury
or damage occurs, the drive must always be firmly attached to the wall
or the floor before further installation work is carried out.

Clearances

The drive is cooled by air circulation. For proper cooling, the minimum
distances above and below the unit must be maintained as shown in the
table below. For units in an auxiliary enclosure with the drive mounted
on a backpanel, the required clearances are measured from the top
and bottom of the drive, not the backpanel.
Drive Size
1 to 3 hp, 200-240 V
1 to 10 hp, 380-460, 550-600 V
5 to 30 hp, 200-240 V
15 to 75 hp, 380-460, 550-600 V
40 to 60 hp, 200-240 V
100 to 125 hp, 380-460, 550-600 V
150 to 300 hp, 380-460, 550-600 V
350 to 600 hp, 380-460 V
All drives can be mounted with no side clearance. Sufficient space must
be provided in front of the drive for door swing on units with a hinged
door. TR1 drives 350 hp and above require 25 inches (605 mm) front
space for access. In addition, sufficient room must be available for
installation and service access. On units with an auxiliary enclosure,
the auxiliary enclosure door will have a greater door swing than the
drive. See the dimensional drawings of the auxiliary enclosure which
are included with the drive.

Backplate Requirements

Mount directly to the wall all drives without a backplate. This ensures
that air flow is in contact with the heatsink all the way from the bottom of
the drive. If this is not possible, a metal plate at least as large as the
back of the drive may need to be firmly mounted to the back of the drive
(see tables below). A backplate assembly is available from Trane.
Drives without a backplate must be mounted directly to a solid wall with
no spacers between the drive and the wall. Free-standing drives without
a backplate require a backplate to be mounted.
