Cleaning, maintenance
Cleaning and maintenance only by qualified electricians.
Danger to life from electric shock.
- Prior to accessing the connection terminals, switch off all supply circuits. Switch off mains fuse, secure against being accidentally switched back on and position a visible warning sign.
If required, the unit is cleaned with a dry cloth. The cleaning intervals are to be determined by the operating company – frequency depends on ambient conditions and expected impairments.
Maintenance: If an upstream TFE air filter is used, the unit is maintenance-free. Without an air filter, clean the unit regularly.
