Operate your appliances responsibly, especially when controlling them with remote controls or over the Internet. Remote control of appliances in an Asema system is disabled by default to prevent accidental damage.
Enable remote control only on devices where you can be certain damage cannot occur due to for instance
heat, fire, smoke or water you do not notice while not present.
Always use an authorized and qualified electrician when installing products that involve rewiring electrical
connections, changes to the distribution box, or opening wall sockets or other components embedded into
walls, floors, or ceilings. Live cables can only be accessed by a qualified electrician.
Do not force or bend the cables at any point during installation. Do not drop, throw or try to bend the
product. If you are worried or have any concerns about the installation, please contact a qualified electrician
immediately.

short circuit. Keep the device away from extreme temperatures.
If this product is equipped with a USB port for connecting to a power or a computer, note that connecting
to improperly grounded equipment can result in an electric shock to your device. Be sure your computer is
properly grounded (earthed) before connecting this product to a computer.
Do not use this product in gas stations, fuel depots, chemical plants or where blasting operations are in
progress, or in potentially explosive atmospheres such as fueling areas, fuel storehouses, below deck on
boats, chemical plants, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust, or metal powders. Please be aware that sparks in such areas could cause
an explosion or fire resulting in bodily injury or even death.
This product may cause medical equipment to malfunction. The use of this device is forbidden in most hospitals and medical clinics.
There is no need to open the product. YOUR WARRANTY IS INVALIDATED IF YOU DISASSEMBLE OR ATTEMPT TO DISASSEMBLE THE DEVICE.
1. Installation
Important
The Asema M2 should be installed by a qualified electrician only.
1.1. Locating the leads and attaching the clamps
Locate the three incoming phases in the fuse box, going to the main fuse/power switch. Attach the
current clamps onto the leads as indicated by the installation diagram on the device. The clamps
are attached to the lead only, do not attach them to the neutral. Note the numbering on the
clamps, this must match the numbering of the phases to correctly display the power consumption
of that phase.
1.2. Connecting to power
The Asema M2 is powered by 230V power from one of the phases. You may freely choose the
phase. Do not take power from the incoming phases, always draw the power from a lead located
behind a proper circuit breaker.

2. Pairing and communicating with
Asema E
In order for the Asema E to communicate with the Asema M series meters, they need to be paired
first. After pairing the Asema E can receive power measurement data in an encrypted format for
maximum privacy and security. Pairing can be done either using the touchscreen of the Asema E,
or in the WebView.
2.1. Pairing the meter
To pair the meter with Asema E, first enter the Main setup. Then proceed as follows.
1. At the main setup go to Appliances->Central Meter.
2. Click “Detect”. The Asema E will now scan all compatible meters which are not yet paired. This
can take a few seconds. Once a meter is found, you will be prompted to accept it.
3. Once you have accepted the meter, a form will appear showing its details with default fields
prefilled. Edit the values as appropriate or simply leave the default values.
4. You're done! Once you leave the form, pairing will take place automatically and your settings
are stored.
2.2. Test reading with radio quality measurement
To make sure your Asema M series meter works without problems, it is recommended to take a
test reading from it. Enter the Central Meter menu in the Main Setup and press the "Test" button.
This will attempt to read the current measured value from the meter. You will be shown the radio
quality statistics as well as whether the test reading was successful.
If the test fails
1. Ensure that the Asema M meter is still connected to the mains power and within radio range.
2. Observe the radio quality statistics. If the signal quality is under 20% or packet loss is excessive
(over 30), you are likely to have trouble operating the unit.
2.3. Removing the meter
If you want to remove the Asema M meter from the system, proceed as follows:
1. Enter the Central Meter setup either on Asema E touchscreen or in the WebView.
2. Click/tap on the "Delete" button to start the unpairing process.
3. Wait until the process is done and you get a confirmation. You're done removing the meter.
If for some reason the unpairing process fails despite retrying it a couple of times, you can still
remove the meter. Click/tap on the "Advanced" button, read the warning concerning resetting the
meter and use the delete function here to remove the meter without resetting it. Note that you
will need to manually reset the meter to be able to pair it again. See for Section 2.4, “Resetting
the meter” details.

2.4. Resetting the meter
Each Asema M series device has a dedicated reset button for removing pairing data from the meter
itself manually. You should always try to reset the meter from the Asema E first before doing
a manual reset.
A manual reset will simply remove the pairing from the meter without telling about this to an
Asema E. It will therefore result in a "ghost" meter on the Asema E that can no longer be reached.
You can however remove it from the Advanced settings of the meter on Asema E. Please refer
to Asema E manual for more information.
The manual reset is needed if you have lost pairing data on your Asema E due to replaced equipment, accidental deletion or other similar reason. To perform the manual reset, you must have the
meter connected to mains power. Then simply press the reset button.
You can find the reset button as follows
• On an Asema M1, the reset button is the transparent button with blinking red LED light
• On an Asema M2, the reset button is the gray button in front, marked with "RESET"
2.5. Mesh networking
Mesh networking means that Asema controllers and meters with a radio can relay messages automatically between them and this way extend the range of communication or go around obstacles.
Thus they work automatically as repeaters of messages for each other. Asema S series controllers
and Asema M series meters will automatically form a mesh network when they detect each other.
Mesh networking is automatic, you do not have to do anything to enable mesh networking, the
devices will do this automatically. However, you may benefit from knowing the topology of the
mesh network as placing a controller between the Asema E and an Asema M meter that have
trouble communicating with each other may improve the situation.
To get most out of mesh networking, test the connection to the meter with the "Test" button.
If you get poor radio coverage (high packet loss or low radio quality) this means that the radio
is suffering from disturbance due to distance or obstacles. Placing a controller in a location that
is between the two devices, possibly so that it allows to bypass an obstacle, will improve your
installation.

3. Troubleshooting
This section lists a few common problems you may encounter into while using your Asema M meter
and common remedies to them. For a more complete list of howto's and up-to-date answers to
problems, visit the FAQ section on our support website at support.asema.com.
• Cannot detect the meter
If a meter cannot be found when you try to pair it, the problem can be the cause of four basic
reasons: 1) the meter is not connected to mains power, 2) the radio reception is poor, 3) the
meter is already paired, or 4) the meter is broken.
First make sure the meter is properly connected to mains power. The ensure there are no interfering obstacles between the meter and an Asema E and the distance between the two does
not exceed 30 meters.
Check that the meter is not already paired. A paired meter no longer sends a beacon and cannot
therefore be detected. To have the meter send beacon again, reset it either from the Asema E
(in case of a meter paired to that Asema E) or from the reset button.
• Cannot pair a meter
Pairing a meter requires a good radio connection between the meter and Asema E. Make sure
you have no interfering elements between the devices and the distance between them is sort
enough. For troubleshooting purposes you may want to move your Asema E closer to the meter
to see how distance affects the radio connection.
