Introduction
The Kwhiq IQ0102065BNEM electricity meter is a single-phase smart meter developed for measuring
and monitoring energy to enable good energy management. Many energy parameters (such as
energy, voltage, power, ...) are measured, logged and made available. The meter can be read and
congured via the mobile network (4G / 2G).

Installation
Choose a suitable location with sufcient signal strength
The meter should be installed in a dry and well-ventilated location. The meter or the installation board
should be placed against a robust, re-resistant solid wall. In case of any doubt (e.g. in basements),
use a telephone and reference meter to check the signal strength of the mobile network in advance.
Fix the meter
Respect the safety regulations and act in accordance with the user manual of the meter.
Dimensions: 210mm x 131,6mm x 85.8mm
Materials:
– Pozidriv screwdriver PZ no.2 for the screws on the terminal block.
– 3 Self-tapping M5 screws with countersunk head for xing to the wall or panel.
– Drill with M5 stone drill bit and 3 plastic plugs for installation against a concrete wall.
Check the meter before connecting it. Only connect the meter if there is no visible
or audible damage or defect (loose parts). Meters that have been dropped
may not be installed, even if no damage is visible. They must be returned to
the manufacturer for inspection. Internal damage may cause short circuits or
malfunction.
The meter is xed at 3 points: 1 hook at the top and 2 screw holes.
The hook can be adjusted to 3 positions. First hang the meter on the hook at the top
and then attach the 2 screws.
Connect the meter
First de-energise the side of the circuit to which the meter is to be connected. Make sure that the
circuit cannot be re-energised by accident.
Connect the meter as indicated below.

Installation Guide On-site installation procedure PV monitoring with Xemex KWHIQ meter
The kwhiq meter is equipped with terminal connectors that allow the use of wires with a section
of 2.5 to 25 mm2. If a solid cable is not used, the correct cable ferrules must be tted. The terminal
connectors are tted with M7 x 13 cross-head and slotted-head screws that must be tightened with a
Posidriv PZ No. 2 screwdriver to a torque of at least 3.5Nm.
The 1-phase meter is connected with side of mains or meter box to L (terminal l) and N (terminal 4).
See also the diagram on the inside of the terminal cover.
Important: if the connection of the meter box and solar panels is reversed, the solar panels will work
but the monitoring will not! You can check whether the meter is correctly connected by looking at
the display. This must be done with a working installation: there must be PV production. The display
shows an arrow on the right with -P as caption. It must point to the LEFT.
Fit the terminal cover. On the underside, the correct routing can be cut out for the cable.

Power up the installation
The display becomes active and the ‘Power’ led lights up continuously. The ‘Status’ led lights up
continuously (looking for a network) or ashes slowly (0.8 sec. on and 0.8 sec. off: registered on the
network but cannot receive a data connection yet).
Immediately after switching on the voltage, the arrow may point to the right (+P). This is because the
inverter needs time to start up. During this start-up period, the inverter consumes electricity from the
grid so that the arrow points to the right. You must wait until the inverter actually delivers solar power.
→ If the arrow continues to point to the right (+P), electricity is owing, but in the wrong direction.
The meter might be connected incorrectly. Another possibility is that there is not enough sunlight
to feed into the grid and the inverter is using enough power to be visible on the meter. If there is no
sunlight (or if the PV plant is not working for another reason), it is also possible that there is no arrow
on the display at all. In these cases, please check whether the meter is connected properly.
Registration on the GSM network
– Maximum 5 minutes after start-up, the ‘Status’ LED will start ashing faster (0.2 sec. on and 0.2 sec.
off).
– In the meantime, the network symbol has also appeared in the display.
– The meter is now registered on the GSM network and able to receive a data connection.
– Usually the meter will not need 5 minutes but will be ready after +/- 25 seconds.
If the ‘Status’ LED does not ash quickly 5 minutes after start-up, there is probably no mobile network
coverage at that location and the meter should be moved to a location where there is.
Check the connection
Check that the arrow on the right of the display points to LEFT.

Installation Guide On-site installation procedure PV monitoring with Xemex KWHIQ meter
Check the signal strength
The network symbol at the top right of the display indicates the signal strength of the GSM network at
that location:
Excellent (rsrp >= -80 dBm)
Go0d (rsrp >= -90 dBm & rsrp < -80 dBm)
Sufcient (rsrp >= -100 dBm & rsrp< -90 dBm)
Insufcient (rsrp >= -120 dBm & rsrp < -100 dBm)
No signal (rsrp < -120 dBm)
If there is no signal, or if the signal is insufcient or poor (less than 2 bars at the network symbol)
the meter should be moved to a place where the signal strength is sufcient. An external antenna
can be used (optional item). In this case, the meter can remain at the location without network
coverage because an antenna is installed at the location with sufcient signal. The external antenna
is connected to the meter with a cable. The connection point (MCX connector) is located under the
communication module cover. This section is sealed. The seal must therefore rst be broken and a
new seal must be placed after the antenna cable has been connected.
Installing an external antenna
1. Remove the seal from the communication module.
2. Remove the cover from the communication module.

3. Install the antenna cable. Connect the MCX connector and tuck the cable into the groove provided.
4. Break out the piece of plastic to allow the cable to come out of the cover.
5. Replace the cover on the communication module and reseal the bolt with a (proprietary) seal.
6. Install the antenna in a location with sufcient network coverage.

Installation unsuccessful
When nothing appears on the meter’s display and the ‘power’ LED does not light up.
Check whether the meter has voltage at the terminal block by means of a voltage tester or voltmeter.
If there is 230V between terminals 1 and 4 but nothing appears on the display, the meter may be
defective. Replace the meter and start an RMA procedure for the defective meter.
If it is not possible to achieve successful conrmation in the Cast4All Connect app. And/or if the
signal strength of the meter remains insufcient.
Check the signal strength of the mobile network by using a reference meter. Only if the reference
meter shows a good signal strength (the value on the screen is updated every 30 seconds) in exactly
the same place will the meter need to be replaced. In this case, write down or lm all the data from
the display. To do this, press the upper blue button and scroll through all the codes of the display
cycle.
All values must be noted in the RMA document.
Check the installation by using the Cast4All Connect app, which can be downloaded from
Apple’s App Store and Android’s Google Play Store.
