Chapter 2 — Mounting Open TYPE 1, TYPE 12 Drives
VSD Series open drives may be mounted side-by-side or stacked vertically, as outlined in the
following section.
Note: See Chapter 5 for mounting TYPE 1, TYPE 12 and TYPE 3R IntelliPass drives.
Space Requirements
To ensure proper air circulation and cooling, follow the guidelines below.
Table 2-1: Space Requirements for Mounting a VSD Series Drive
Dimensions represent the minimum clearance needed when mounting a drive. See Figure 2-1 below.
A = clearance around the VSD Series drive.
A

= clearance needed to change the fan without disconnecting the motor cables.
B = distance between adjacent VSD Series drives or between the VSD Series drive and an enclosure wall.
C = clearance above the VSD Series drive.
D = clearance below the VSD Series drive.
Minimum clearance below the VSD Series drive needed to change the fan.
Figure 2-1: Mounting Space Requirements
If several units are mounted above each other, the clearance between the drives should equal
C + D (see Table 2-1 and Figure 2-1 above). In addition, the outlet air used for cooling the
lower unit must be directed away from the inlet air used by the upper unit.
