The device may only be mounted and connected
by an electrical technician.
General safety information
–Before working on power cables, ensure that
they are de-energised and secure them against
unintentional switch-on.
–Do not mount the device during a thunderstorm.
–Comply with national laws and standards, e. g.
VDE 0100-534 (IEC 60364-5-53).
Mounting the device
Risk of fire!
WARNING
If the maximum current capacity is exceed-
ed, it can cause a short-circuit and lead to
a fire.
With V wiring (series connection), observe
the maximum current load of 125 A (100 A
@ UL).
The total connection length of 0.5 m may not be
exceeded on branch wiring and V wiring (Figure
).
Suspended the device on the hat rail and en
gage it.
Observe the stripping length and tightening
torque.
Connect the cable according to the circuit dia
gram for TN-C or TN-S/TT systems.

Connecting remote signalling
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
(Figure ). This allows activation of suitable sig-
nalling components, such as central error mes-
sages, light or acoustic signal.
–Connect the remote signalling cables as shown,
in so doing observing the specified cable cross-
section and the stripping length.
Dismantling the product (Figure
1. Push the locking hook downwards with a
screwdriver.
2. Pull the device forwards and remove it from
the hat rail.
Maintaining the product
We recommend carrying out a visual check of
the visual display every 2-4 years or after light-
ning strikes. If the integrated cut-off unit trips
(e.g. due to age on account of multiple, very high
surge voltages), the display switches from green
to red.
–If the visual display is red, the surge protective
device must be replaced.
Disposing of the product
–Packaging as household waste.
–Protective device as electronic waste.
Comply with the local waste disposal regulations.
