Make sure to connect the (longer) 2-wire cord from the power supply
unit (24V or 110/230V) in the right compartment to the power connector
(2). For more information about PSU, please see manual for CMip2110/
WZU-AC230-xx.

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 Landis+Gyr WZU-BC+GUM battery has to be
inserted into the left compartment. Mount the Landis+Gyr WZU-NB-
IoT-BAT (battery+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.

Make sure to connect an external antenna (released by the supplier)
with MCX connector to the module in the UH50/UC50. The image
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.
MOUNTING
Before mounting the module in the meter, make sure that a SIM card is
installed in the SIM card slot (7) as illustrated below.

Upon delivery, CMi6110 has a standard conguration. If you would like
to change conguration, please download the Elvaco OTC Application
(One-Touch commissioning) for Android, available in Google Play store.
The Elvaco OTC connects to the module via NFC.
By default, the product is set to passive mode, which means no
messages will be transmitted from the device. There are two ways to
activate the product:
1. Press and hold down the push button (4) for at least 5 seconds until
the green LED (8) lights up.
2. Read the meter via NFC to activate the Apply tab in the Elvaco
OTC app. Go to the Apply tab, set the Power mode to “Active”, push
“Apply” and place the phone on the right side of the meter, next
to the module. Make sure to hold the phone still until the phone
vibrates.
Upon start-up, the module will attempt to connect to the mobile
network. The phase is indicated by short flashes on the green LED.
After successfully connecting to the mobile network, the green LED will
lighten up for 8 seconds, as indicated by the gure below.

• Make sure to locate the NFC antenna on your phone. When you
scan or write new congurations to the module, you should place
the phone’s NFC antenna as close as possible to the NFC antenna
of the module (6). The best place is on the right side of the meter.
