1. Safety Information
Please observe the technical data of the pulse out-
put..
Ensure ESD protection.
Avoid short-circuits on the PCB.
Always route connecting cables through the grom-
mets of the meter.
Do not cut the grommets shorter than necessary
since this may lower the degree of protection.
Only ever touch the module on its plastic holder.
The meter has no lightning protection. Ensure light-
ning protection via the house installation.
2. Description of function
The pulse output module T45-PULSE enables the output of
pulses on 2 configurable channels.
On channel 1 (terminals 16, 17)
• energy (CE)
• volume (CV)
• tariff register 1 (C1)
pulses can be output.
On channel 2 (terminals 18, 19)
• volume (CV)
• tariff register 1 (C1)
• tariff register 2 (C2)
pulses can be output.
The pulse duration is identical on both channels.

4. Parameterization
The pulse function is pre-parameterized with CE for channel 1
(CH1) and CV for channel 2 (CH2).
An adjustment can be made via UltraAssist.
Pulse value

4.1 Installing the communication
Proceed as follows to install a communication module:
• If necessary, open the housing cover by loosening the
screw.
• Run the cable from the outside through the grommet.
• Strip and connect the cable.
• Secure the cable with the strain relief clamp.
• Connect the cables to the module’s terminals.
• Pull the cables out through the housing while inserting the
module.
• First attach the contact surfaces of the module to the mod-
ule slot.
• Gently push the module in.
