Communication Modules - Siemens UH50 Serie Montageanleitung

Installing power supply module
Note: The 110 V / 230 V connections may only be
made by an electrician.
To install a power supply module proceed as follows:

Move the red locking hatch to the left.

Move the right outside rubber sleeve upwards and out-
wards.

Thread the connection cable of the line voltage of the
module through the sleeve.

Insert the module into the right upper corner of the elec-
tronic unit.

Put the sleeve with the cable back into place from above.

Connect the conductors in line with the inscription.

Plug the connection cable for low voltages into the plug
connector on the PCB.
Note: Only use cables with a diameter of 5.0 ... 6.0 mm
for the 24 V ACDC version.
Note: The 110 V or 230 V power supply must be fused
near the meter with a 6 A separator in accordance with
the applicable safety standards. The separating device
must be marked in accordance with applicable safety
standards and be easily accessible for emergencies.
Protect the power supply against manipulation.
Power supply module for meter exchange
Proceed as follows to exchange the meter following expiry of
the validity of the calibration:

Pull out the power supply module with cable and sleeve.

Install the new meter.

Put the module in.
Note: The network does not need to be disconnected
while doing this due to safety class II.
Electronic unit interfaces
The meter is equipped with an optical interface in accordance
with EN 62056-21:2002 as standard. You can additionally use
for remote reading up to 2 of the following communication
modules:

Pulse module

CL module

M-Bus module G2

M-Bus module G4

M-Bus module G4 MI with 2 pulse inputs

Analog module

Radio module 434 MHz

GSM module

GPRS module

Radio module 868 MHz

Zigbee module
These modules do not have an effect on the measurement.
You can retrofit the modules at any time without damaging the
security seal.

Note: Observe the necessary ESD protective measures
while installing modules.
Up to 2 communication modules can be installed. No power
supply module is installed in the standard version.

Installing the communication module
The communication modules are connected via a 6-pole reac-
tion-free connector so that installation or replacement is possi-
ble at any time.
To install a communication module proceed as follows:

Put the communication module into the correct position.

Place the communication module carefully in both the
guide slots and push it in.

To connect an external cable, open the sleeve matching
the cross section of the connection cable.
Note: Open the cable sleeves in such a way that they
enclose the cable tightly.

Guide the cable through the sleeve from outside.

Strip the cable and connect it.
Note: Do not connect the shielding braid on the meter
side.
Note: Take note of the permitted combinations and
the correct slot for the communication modules.
Note: You will find the technical details and data on
communication modules in their documentation.
Note: You will find the permitted combinations in the
UH50.. configuration instructions.
Note: The meter recognises the inserted modules
independently 30 seconds at most after installation
and is ready for communications or pulse output.
Note: The type of module inserted can be displayed
within the service loop depending on the display
parameterisation.
