5.3.2 24 V DC Remote closing (option)
The panels concerned are provided with:
auxiliary contacts as described under remote signalling;
a controller;
a trip coil;
a closing motor;
a closing pushbutton on the frontside of the panel.
If the supply voltage < > 24 V DC, then an optional
universal voltage converter is mounted.
For on-site commissioning:
1. Check that the power supply is live.
2. Use the position indicator (9) to check that the
change-over switch is fully in the busbar position.
3. The control knob for the selector (7) should be in the
central position.
4. Closing will follow once the load-break switch or
circuit-breaker is opened and the closing contact on
the relevant terminals of the terminal strip is closed.
The closing procedure starts with the spring being
tensioned, the actual closing takes place after approx.
12 seconds.
5.4 24 V DC Tripping for external protection
(option only for circuit-breaker)
The panels concerned are provided with a trip coil only for
24 V DC. An optional universal voltage converter is not
possible in this design.
For on-site commissioning:
1. Check that the supply voltage is live.
2. Use the position indicator (9) to check whether the
change-over switch is fully in the busbar position.
3. Tripping will follow once the circuit-breaker is closed
and the tripping contact on the relevant terminals of
the terminal strip is closed.
5.5 Local closing
The panels concerned can also be switched on locally
using the local electrical closing pushbutton. This is subject
to the same conditions as the remote closing cycle.
Press the electrical closing pushbutton in order to close (1).
