Commissioning and functional check

© Landis+Gyr
Only a properly connected meter can operate correctly. Installation
errors will result in a financial loss for the utility company.
Ensure the following points are satisfied before powering the meter and
correct as necessary.
1. Cross-reference the meter type number and serial number to
confirm that the correct meter has been used for the installation.
2. Check the factory fitted calibration seal is in place and secure.
3. Check all phase terminal screws are tightened to the correct torque
(max. 3 Nm).
4. Fit terminal cover and seal with company seal if applicable.
Do not touch live parts
It is necessary, in order to put the meter into service and perform a
functional check, to replace the preliminary fuses. The connecting
conductors will therefore become live. Electrically live parts are a life
threatening hazard. If any modifications to the installation are required,
preliminary fuses should be removed and kept in a safe place, where
they cannot be replaced by anyone unnoticed, until all work is complete.
Once satisfied that it is safe to do so, replace the preliminary fuses, and
the meter will power on.
The installed meter should be put into service and checked as follows:
1. Insert the preliminary fuses removed for installation. The meter is
switched on.
2. Check whether the operating display appears correctly (no error
message).
3. Check on the display whether all three phases L1, L2 and L3 are
indicated and show the phase sequence.

If one phase is not present, the relevant symbol is absent. This is
also the case if the voltage is less than 25% U

With the normal phase sequence L1-L2-L3 the symbols are
displayed continuously.

If the meter is connected with a reversed phase sequence (e.g. L2-
L1-L3) the symbols flash. The direction of field rotation (clockwise or
anticlockwise) is determined by parameterisation. This has no
influence, however, on the measuring behaviour of the meter.
Caution
Some of the aids described here are not available depending on the
version for a specific country.
