5.3 

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. M
ount 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.
