Mounting Requirements
All units are fan cooled. It is important to locate the controller in a position
that allows air to flow vertically through the power module.
See Table 2
for minimum enclosure dimensions.
When you drill or install near the soft starter, make sure that you take adequate
measures to protect the device from dust and debris, as shown in Figure 1
.

IMPORTANT
The controller must be mounted in a vertical plane and have a minimum of 6 in.
(150 mm) free space above and below the controller. Horizontal mounting of the
SMC-50 controller is not allowed. Enclosure must be sized such that the enclosure’s
internal temperature remains within specified controller ratings.
