Guidelines for planning the cabinet installation
Contents of this chapter
This chapter gives ACS880-01, ACS880-11 and ACS880-31 specific guidelines for planning drive cabinets and installing the drive modules into a user-defined cabinet. The guidelines are essential for the safe and trouble-free use of the drive system.
Limitation of liability
The installation must always be designed and made according to applicable local laws and regulations. ABB does not assume any liability whatsoever for any installation which breaches the local laws and/or other regulations. Furthermore, if the recommendations given by ABB are not followed, the drive may experience problems that the warranty does not cover.
Generic cabinet planning instructions
See Drive modules cabinet design and construction instructions (3AUA0000107668 [English]) for
• cabinet construction: disposition of the devices, grounding of mounting structures, busbar material and joints, shrouds and tightening torques
• cooling and degrees of protection
• EMC requirements
• fastening the cabinet
• cabinet placement on a cable channel
• planning the use of cubicle heaters
• control panel mounting platforms.
16 Guidelines for planning the cabinet installation
Vibration dampers
Vibration dampers are not needed in cabinet installations of ACS880-01, ACS880-11 and
ACS880-31 drive modules.

Minimum air inlet and outlet grating sizes
Make sure that the air inlet and outlets are large enough to allow sufficient air flow in and out of the cabinet. This is critical for the correct cooling of the drive module. See the minimum grating sizes below.

Preventing the recirculation of hot air
Prevent hot air circulation outside the cabinet by leading the outgoing hot air away from the area where the inlet air to the cabinet is taken. Possible solutions are listed below:
• gratings that guide air flow at the air inlet and outlet
• air inlet and outlet at different sides of the cabinet
• cool air inlet in the lower part of the front door, and an extra exhaust fan on the roof of the cabinet.
Prevent hot air circulation inside the cabinet with, for example, leak-proof air baffles. No gaskets are usually required.

Free space requirements
The required free space at the top and bottom of the drive module is shown below. The free space is needed to make sure that the module cools correctly.

Planning the cabling outside cabinet
See the cable routing instructions in the hardware manual.
Installing ABB common mode filters (option +E208)
Common mode filter kits are available as options from ABB. For drive modules without the cable entry box, hang the common mode filter ring on the cabinet structure.
For the dimensions of the ring and installing of the motor cable through the ring, see
