Installation instructions
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
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
greeen (grey) to red. In this case, remove the ar-
rester and insert a new arrester (available sepa-
rately, 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 ar-
resters of this device have experienced the same
load. We recommend that you check them and, if
necessary, also replace them. Dispose of re-
placed arresters.
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.
