External master MI3-02M, MI3-02M/iNELS2

• External master MI3-02M provides expansion of the amount of units
iNELS3 connected to the central unit CU3-01M or CU3-02M of two
other lines of BUS (i.e. about 2×32 peripheral units).
• If you require the use of a central unit CU3-01M (02M) in combination
with the iNELS2 units, all the units must be connected to the BUS lines,
which are based on an external master MI3-02M/iNELS2.
• Through the system BUS EBM, it is possible to connect to one central
unit up to 8 external masters MI3-02M or MI3-02M/iNELS2.
• Combining central unit CU3-01M (02M) and 8 external masters MI3-
02M we can reach maximum capacity of iNELS system up to 576 peripheral units.
• If you require an extended system then it is possible to use communication of up to 8 central units with Connection server using ELKONET
protocol, eventually the integration of more central units into BMS via
ASCII protocol.
• MI3-02M and MI3-02M/iNELS2 have marked on the front panel of the
unique hardware address. This address belongs to the line BUS1. Hardware address of BUS2 line is always one value higher than for BUS1.
• MI3 units are supplied from PS3-100/iNELS.
• To power the lines BUS, it is necessary to use a BUS separator BPS3-02M
or BPS3-01M (supply only one line). In case of using MI3-02M/iNELS2 is
used BPS2-02M or BPS2-01M.
• Status signaling of each BUS (operation, fault) is indicated by twocolor LEDs on the front panel of the module.
• The last MI2-02M connected to the EBM BUS must be closed with
a 120 Ω termination resistor. This part adapted to be inserted between
terminals is included into central units packages and it is necessary to
insert between terminals EBM+ and EBM-.
• MI3-02M, MI3-02M/iNELS2 in 1-MODULE version is designed for
mounting into a switchboard, on DIN rail EN60715.
