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