Mount and start-up the device
In order to use CMi6110, a SIM card (size: Nano) needs to be mounted in the SIM card holder (7), see
Figure 3. The module is thereafter mounted in module slot 2 of a L+G UH50 heat meter or a L+G UC50
heat calculator with software version 5.15/8.06 or higher. Grab the module by the outer edges and gently
press it into position.

5.3.1 Mounting PSU power
Make sure to connect the (longer) 2-wire cord from the power supply unit (24V or 110/230V) in the right
compartment, see
Figure 4, to the power connector (2). For more information about PSU, please see manual for CMip2110/
WZU-AC230-xx.
5.3.2 Mounting battery power
Remove the red flap inside the meter. If the right compartment for power supplies is equipped, remove
that battery or power supply unit. For the meter supply, a Gyr WZU-BC+GUM battery has to be
inserted into the left compartment, as illustrated in
Figure 4. Mount the Gyr WZU-NB-IoT-BAT (holder) in the right compartment. Battery
operation is available from FW 1.03. Models with earlier FW can be remotely updated.
•
The battery supplying the meter must be connected before connecting the battery supplying the
CMi6110.
•
Removing the meter’s red flap is only allowed for this purpose!
•
The battery holder (made of isolating material) substitutes the function of the red flap. Once
inserted into the meter it cannot be removed.
5.3.3 Antenna connection
Make sure to connect an external antenna (released by the supplier) with MCX connector to the module
in the UH50/UC50.
Figure 4 below illustrates how the antenna cable should be routed. Push the connector gently into the
socket on the module.
•
The antenna should be mounted at least 0.5 meter away from the meter to avoid interference.
•
The rubber gromets may not be cut.
•
Punch a small hole with 3mm diameter through the gromet.A 3mm hex key (Allen key), for
example, is a suitable tool.
•
Make sure to remove the strain relief (metallic clip) and do not remount it due to the risk of
damaging the antenna cable. If you want to add additional strain relief, mount a cable tie on the
antenna cable, close to the cable entry inside the enclosure.
