Faults
If the integrated cut-off unit trips (e.g. due to age
on account of multiple, very high overvoltages),
the visual display (Figure ) switches from green
(grey) to red. In this case, remove the arrester
and insert a new arrester (available separately,
V20: item no. 5095 364, C20: item no. 5095 600).
In the case of devices with multiple arresters, it
must be assumed that the other arresters of this
device have experienced the same load. We rec-
ommend that you check them and, if necessary,
also replace them. Dispose of replaced arrest-
ers.
Remote signalling
Figure (only V20-..+FS..):
When at least one arrester is disconnected, the
changeover contact in the remote signalling mod-
ule switches from 11/12 to 11/14. Remote signal-
ling can be switched as an NO or NC contact.
This allows control of suitable signalling compo-
nents (e.g. central error messages, light or
acoustic signal).
• Connect the remote signalling cables as
shown, in so doing maintaining the specified
cable cross-section and the stripping length.
Maintenance
We recommend carrying out a visual check of
the visual display every 2-4 years or after light-
ning strikes.
Disposal
– Packaging as household waste
– Protection device/arrester as electronic waste.
Comply with the local waste disposal regulations.
