Dangerous voltage on conductors
The connecting wires at the place of installation must not be live when
removing the meter. Touching of live parts is dangerous to life. Remove the
corresponding supply fuses and keep these in a safe place until work is
completed, so that they cannot be replaced by anyone unnoticed.
The meter should be removed as follows:
1. Remove the two utility seals at the screws of the terminal cover.
2. Release the two screws of the terminal cover and remove it.
3. Check that the connecting wires are not live using a phase tester or
universal measuring instrument. If they are live, remove the
corresponding supply fuses and keep these in a safe place until work
is completed, so that they cannot be replaced by anyone unnoticed.
4. Remove the connecting wires of the signal inputs and outputs from the
screwless spring-loaded terminals as follows:
– Place a size 1 screwdriver in the upper opening and insert it turning
slightly upwards (figure 52 A).
– Then draw the wire from the lower opening (figure 52 B).
– Withdraw the screwdriver (figure 52 C).
