Clearances<br />
<strong>Altivar</strong> ® <strong>31</strong> Adjustable Speed AC Drives<br />
Mounting<br />
Install the drive controller vertically, ±10°.<br />
Do not place the drive controller close to heating sources.<br />
Leave sufficient free space around the drive controller to ensure that air can<br />
circulate from the bottom to the top of the unit. Leave a minimum of 10 mm<br />
(0.4 in.) of free space in front of the drive controller.<br />
Removing the protective cover<br />
When IP20 protection is adequate, remove the protective cover on top of the<br />
drive controller as shown in the figure to the left. Consult “Mounting methods”<br />
below to determine the type of mounting appropriate for your application<br />
before removing the protective cover from the drive controller. For UL Type 1<br />
protection, the protective cover must remain installed on the top of the<br />
controller and a conduit entry kit must be installed.<br />
Mounting methods<br />
Refer to the derating curves on page 30 to determine which mounting<br />
method best fits the application.<br />
Type A Mounting Free space ≥ 50 mm (1.97 in.) on each side, with the protective<br />
cover in place.<br />
≥ 50 mm<br />
(1.97 in.)<br />
≥ 50 mm<br />
(1.97 in.)<br />
Type B Mounting Drive controllers mounted side-by-side, with the protective cover<br />
removed (degree of protection becomes IP20).<br />
Type C Mounting Free space ≥ 50 mm (1.97 in.) on each side, with the protective<br />
cover removed (degree of protection becomes IP20).<br />
≥ 50 mm<br />
