MOUNTING<br />

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 />
