The exterior diameter must be between 4 and 6 mm. All wiring must be able to be guided to
the meter through the existing bushings. It may be convenient to connect the cables before
the meter in a single multi-conductor cable on a split box.
Do not connect shielded cables to the side of the meter (connect to one end only).
Pulse module
WZU-P2
Function description
The pulse module WZU-P2 enables the meter to communicate with a pulse collector to
transmit measured values. It outputs pulses that can be derived from the energy, volume,
tariff register 1 or tariff register 2. Two channels are available; their function can be adapted
using the service software.
The outputs are in the form of standard pulses or "fast pulses". The pulse duration is
identical for channel 1 and channel 2.
NOTICE
The module can be plugged into both slots, but fast pulses can only be output via slot 2.
