Fans

The lifespan of the cooling fan depends on the running time of the fan, ambient
temperature and dust concentration. See the firmware manual for the actual signal which
indicates the running time of the cooling fan. To reset the running time signal after a fan
replacement, contact your local ABB representative.
Replacement fans are available from ABB. Do not use other than ABB specified spare
parts.
