7. MID COMPLIANCE
The following points must be taken into consideration to ensure that the device is used in compliance with directive
MID 2014/32/EU:
• Type of network
COUNTIS E26 meters comply with the MID directive for connection to networks: 3P+N and 3P (see "6.2.
Connection to the electrical network and to the loads", page 10)
• Fitting terminal covers
After connecting the device, ensure that the terminal covers are tted properly and secured by the plastic
seals provided with the device.
• Locking the program button
Make sure the SET program button is locked after tting the terminal cover.
• Communication
The information provided via the M-Bus COM is transmitted for information only and has no legal value.

8.1. General information
In a standard conguration, an M-Bus connection is used to connect 250* devices to a PC or a controller over a
distance of 1000 metres.

8.2. Recommendations
Use a non-shielded JYSTY Nx2x0.8 mm twisted pair (0.5 mm²).
If the distance of 1000 m is exceeded and/or the number of devices is greater than 250, add a repeater to allow
additional devices to be connected.
If there are more than 250 units, use the secondary address only.
8.3. Communication structure
The device communicates via an M-Bus protocol which involves a dialogue in accordance with a master/slave
structure. The COUNTIS units (slaves) are compatible with the 2 primary and secondary addressing modes. You can
congure the primary and secondary addressing modes via the device's interface.
8.4. Communication tables
The communication tables and relevant notes are available on the
COUNTIS E25/E26 documentation page on the website at the
following address:
www.socomec.com/en/countis-e2x
