The PDC modules are each powered from a lithium
battery, which - depending of the input channels and
the sending interval - has a lifetime of up to 15 years
(wM-Bus) and 10 years (LoRaWAN

3.Installation respective retrofitting of the PDC to a
meter
The ZENNER PDC modules are designed primarily for
all water meters of ZENNER which can be retrofitted
with a pulse generator (model -N). Basically, a PDC
can be connected to any meter with suitable pulse
output.
Note: Potential-free (reed) contactors as well as
electronic pulse outputs can be connected to the PDC.
When connecting the PDC module to meters with
electronic pulse output, however, we recommend that
you carry out a compatibility test in case of doubt, as
it can sometimes happen that the compatibility is not
guaranteed.

Connect the pulse output of the meter with the
PDC-cable. Use a cable connector and possibly
observe the correct polarity.
3.2. Connection (retrofitting) PDC IP54 with pulse
output of any meter
Connect pulse output cable from the meter to the
corresponding terminals on the PDC circuit board.
