8. Fit the meter with 3 fixing screws on the mounting surface provided.
Remove main fuses before connecting
The connecting wires at the place of installation must not be live when
fitting the meter. Touching live parts is dangerous to life. Remove the
corresponding main fuses and keep them in a safe place until work is
completed, so that they cannot be replaced by anyone unnoticed.
Provide overcurrent protection
For ZxF100xB meters: As the supply control switch is not equipped with a
thermal and/or short circuit protection device, it needs to be protected with
an external fuse or overload switch.
For ZxF100xC meters: As the meter has no internal overcurrent protection
and no method of disconnection from the mains, this must be provided by
the end installation.
1. Shorten the phase connecting wires to the required length and then
strip them.
2. Insert the phase connecting wires into the corresponding terminals (the
terminals are numbered as shown in the connection diagram) and tighten
the terminal screws firmly (max. torque 3 Nm).
It is recommended to identify the beginning and end of the relevant
conductors with a suitable test unit (e.g. buzzer) to ensure that the right
consumer is connected to the meter output.
