12 Maintenance and cleaning

The product does not require any
maintenance. Enlist the help of an expert to
carry out any repairs.
The HM-LC-Sw1-PB-FM, HM-LCSw2-PB-FM
and HM-LC-Bl1-PB-FM devices have internal
fuse protection. The fuses protect the device relays
against excessive current load. If the device is
overloaded and the fuse blows, it can be replaced
by an expert.
The mains voltage must be disconnected before
the device is removed (trip the miniature circuit-
breaker). Only qualified electricians (to VDE 0100)
are permitted to carry out work on the 230 V mains.
Replacement fuses must always be of the
same type (round fuse 5 A slow-blowing).
