Air Cooling; Air-To-Air Heat Exchangers; Acs6000 Example Drive With Air-To-Air Heat Exchanger - ABB ACS6000 User Manual

3.3.6.1 Arc detection with Arc Guard (optional)
If the drive is equipped with an Arc Guard System for fast arc fault
detection in the terminal sections, the arc monitor and the related HMI
panel are mounted in the roof extension box (REB).
Note: For more information, see "8.11 Arc detection with the Arc Guard
System™ (optional)" on page 197.

Air cooling

Air-to-air heat exchangers and auxiliary fan units can also be used for non-
water-cooled components in the drive.
3.4.1

Air-to-air heat exchangers

Drives for high-power applications are equipped with air-to-air heat
exchangers. They ensure a constant air flow through the medium voltage
units and transfer the heat losses of non-water-cooled components to the
exterior. The fans of the air-to-air heat exchangers are controlled by
the drive.
The auxiliary power for the heat exchangers is supplied by an
additional transformer.
Note: For information on number and location of heat exchangers and
transformer, see "Appendix C – Mechanical drawings".
The number of installed air-to-air heat exchangers and transformers
depends on the configuration of the drive.
