Quick Guide
1. Read the signal strength on the module's Light Emitting Diodes (LEDs) (Min.
two must be switched on).
2. If the signal strength is below 2, an external antenna must be installed*.
3. The external antenna must be placed in a location that optimises the
reception of the signal. Change the position of the antenna until the best
position has been found.
4. Before leaving the installation, test the signal strength by SMS (=signal#).
Make sure that the meter cabinet and doors are closed before sending the
SMS.
* An external Triangle antenna must always be mounted on GSM8i RF 3G
(Order No.: 6699407 or 6699408)
Tips
• Always install an external antenna when installing the unit in a metal cabi-
net. The antenna must be placed outside the cabinet.
• Use dual-band GSM antennas to optimise the performance.
• Note that fire doors, concrete and metal plates disturb and weaken the GSM
signal.
• It is possible to order directional antennas for areas with very poor signal
conditions (please contact Kamstrup A/S for further information).

3 Mounting of GSM8i RF 3G
GSM8i RF 3G, article number 6818xxxxxxxx, is supplied from the meter's
phases and thus differs from the GSM8i 3G base module, and an external
Triangle antenna must always be mounted.
3.1 Mounting order
1. Dismount the top cover of the meter.
2. Insert the SIM card (see paragraph 5.1 “Mounting the SIM card”, page
10)
3. Place the module in the meter's module area (please check that the eight
module pins are all plugged in). Mount the 230 VAC main supply wires as
shown in paragraphs 8.2 to 8.6 - please notice the meter type. Be careful to
lead the wires as shown on the drawings.
4. Mount the external antenna, see chapter 6 “Mounting of external antenna
(to be ordered separately)”, page 11.
5. When the diodes on the module stop flashing, the signal strength is read
on the indicator (see paragraph 4.2.4 “Signal strength indicator”, page
9).
6. If the signal strength is acceptable, mount the top cover of the meter. Avoid
jamming the antenna cable.
7. Before leaving the installation, check the signal strength by sending an SMS
(see chapter 10 “SMS commands”, page 20).
If the module does not indicate normal operating conditions (such as
sufficient signal strength), refer to chapter 9 “Error detection help”, page
19.

4.2.3 Connected to 2G/3G network and meter
The network to which the module is connected, 2G and/or 3G, appears from
the diodes at the bottom of the module. More than one diode can be turned
on. Furthermore, the red METER diode flashes if there is no connection between
meter and module because the module has not been inserted correctly.

5 SIM card
5.1 Mounting the SIM card
The unit can be ordered with the SIM card mounted from the factory. Please
check that the card has been inserted. The telephone number of the card
appears from a label on the side of the module. Kamstrup A/S cannot be held
responsible for theft and misuse of SIM cards from GSM8i 3G units.
When the SIM card holder is opened, the supply to the SIM card is cut off.
When the SIM card has been inserted correctly and the holder is closed, the
module will restart automatically.
If the unit is supplied without a SIM card, make sure that it is inserted before
using the unit.
The SIM card holder is opened by pushing the bright holder back and carefully
tipping up the holder. Next, place the SIM card with the "cut-off" corner in the
top left side and with the contacts facing the PCB.
5.2 SIM card requirements
The SIM card must fulfil the following requirements:
3G/GSM/GPRS, DATA/SMS-9.6kb V110,
PIN code must be disabled, no voice and no pre-paid card can be used.

11
6 Mounting of external antenna (to be ordered
separately)
An external antenna must always be mounted on GSM8i RF 3G!
External antennas with DC resistance between the inner and outer conductors
of 10K ohms or less are detected automatically. This applies to the following
antennas:
• Mini Triangle antenna (order No. 6699448)
• Triangle antenna (order No. 6699407 or 6699408)
• Directional antenna (order No. 6699456)
When using other antennas, the external antenna is selected manually. This is
done in the following way:
By default, the internal antenna has been se-
lected:
The EXT ANT Light Emitting
Diode is switched off:
Antenna selection Button push EXT ANT Light Emitting
Diode
Select external antenna Push twice On
Deselect external an-
tenna
Push three times Off

7 External antenna on GSM8i 3G
Connect the external antenna to the connector on the module. Be careful to
hear a "click" before the two connectors are connected correctly. Place the
antenna cable inside the plastic frame of the module and lead the cable out
through the cable channel at the bottom of the electricity meter. See picture
below.
It is important to notice that the internal antenna must NOT be mounted
together with the external antenna and must therefore be removed!!
IMPORTANT
To ensure that the external antenna is mounted in a way that optimises the
reception conditions, the signal indicator on the module must be followed
(see chapter 4 “Light Emitting Diodes”, page 8). Change the position of the
external antenna until the best position has been found.
Remove the internal antenna and
replace it with an external antenna
