• Clamp the protection device onto the hat rail,
ensuring that the lockable hat rail holder is un-
locked (Figure
2
).
• Maintain the stripping length and tightening
torque (Figure ).
• Connection according to the circuit diagram
(TN-C systems) or (TN-S / TT systems).
Dismantling
Figure :
• Unlock and remove arresters in the manner
shown.
• Open the hat rail holder with a flat screwdriver
and engage it (see also Figure
2
). Remove
the protection devices.
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 grey
to red. In this case, remove the arrester and in-
sert a new arrester (available separately, V50:
item no. 5093 508, C50: item no. 5095 609). 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 V50-..+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.
