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).
For more information, see “8.11 Arc detection with the Arc Guard System™
(optional)” on page 183.
3.4. 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.
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.
