Disconnecting the Meter

© Landis+Gyr
Do not touch live parts
The main fuses must be inserted to put the meter into operation and for the
functional check. Without terminal cover there is a danger of contact with
the terminals. Touching live parts is a danger to life.
The installed meter should be put into service and checked as follows:
1. Insert the corresponding main fuses. The meter is on.
2. Check whether the display appears correctly (no error message) and
with no load connected that the no-load indicators are constantly on.
3. Connect a load and check whether the no-load indicator for active
energy disappears.
4. Check whether the supply control switch (if present) works according
to the functionality specified for your application.
Remove main fuses 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
corresponding main fuses should be removed and kept in a safe place until
work is completed, so that they cannot be replaced by anyone unnoticed.
For ZxF100xB: Do not use the supply control switch as a main switch
for disconnecting purposes! The meter remains connected to the mains!
Remove the meter from the network as follows:
1. Switch off the voltage. The display goes off.
2. Remove the seal at the terminal cover.
3. Release and remove the terminal cover.
4. Ensure with a phase checker that the connecting wires have no
voltage. If there is voltage, remove the main fuses.
5. Remove the connecting wires of the communication module, if
available.
6. Loosen the terminal screws of the phase and neutral connecting wires
with a suitable screwdriver and withdraw the wires from the terminals.
7. Fit a substitute meter as described in section 4.2 "Connecting the
Meter" and the following sections, if necessary.
