Dangerous voltage on conductors
The connecting conductors at the point of installation must be voltage-free
for installation of the meter. Contact with live components is dangerous to
life. The relevant supply fuses should therefore be removed and kept in a
safe place until finishing work, so that they cannot be re-inserted by other
persons unnoticed.
Connecting conductor cross-section
ZMD310CT meters with a maximum current of 100 or 120 A require
connecting conductors of 35 mm² cross-section. Owing to the terminal
opening of 9.5 mm, only cable is possible.
The electrical connections to the meter should be made as follows
according to the connection diagram:
1. Check with a phase tester or universal measuring instrument whether
the connecting wires are live. If so, remove the corresponding supply
fuses and keep them in a safe place until installation is completed, so
that they cannot be replaced by anyone unnoticed.
Connecting the phase connection lines
1. Shorten the phase connecting wires to the required length and then
strip them.
