Remove main fuse before disconnecting
The connecting wires at the place of installation must not be live when
removing the meter. Touching live parts is dangerous to life. The corre-
sponding main fuse should be removed and kept in a safe place until work
is completed, so that it cannot be replaced by anyone unnoticed.
Remove the meter from the network as follows:
1. Switch off the voltage. The display goes off.
2. Move the sliding cover to the service position.
3. Remove the seals.
4. Release and remove the terminal cover.
5. Ensure with a phase checker that the phase connecting wire has no
voltage. If there is voltage, remove the main fuse.
6. Remove the connecting wires of the inputs and outputs, if available.
7. Loosen the terminal screws of the phase and neutral connecting wires
with a suitable screwdriver and withdraw the wires from the terminals.
8. Unscrew and remove the meter.
9. Fix a substitute the meter with the three fixing screws on the mounting
surface.
10. Connect the substitute meter as described in section 4.4 "Connecting"
and the following sections.
