SDM630MCT ETL is a multi-functional din-rail meter designed for accurate measurement an d display of parameters i n 3P3W/3P4W power
grid systems, such as voltage, current, power, frequency, active power, reactiv e power, posi tive energy, reverse energy, total harmonics,
etc. It is an ideal choice for real-time power monitoring, featuring a wide range of functions and applications with high stability over
extended service life. The meter works with an external current transformer and can be applied in both high and low voltage power grid. It
comes with an RS485 communication interface, which supports a maximum baud rate of 38400 bps and enables remote communication.

C.RS485 cable wiring
Connect the RS485A to Pin 14 and RS485B to Pin 13 (The network cables delivered with the inverter are labeled as 485-A and 485-B; if
you are using the cables purchased yourself, mak e sure to differentiate betwe en 485-A and 48 5-B.)
D. Connecting the meter to the Growatt Three-phase
Storage/Hybrid Inve rter E. When connecting the smart meter to the inverter, connect one
end of the cable to Terminal 13 (485B) and Terminal 14 (485A) of
the smart meter and the other end to Pin 6 (485A) and Pin 7 (4 85B)
of the COM1 port.
Note: In most c ases, the re d cable is used f or 485A and the black
cable for 485B.
G. The standard RS485 cable length is 15m. If a longer RS485
cable is required, plea se use an intact cable and make sure the
RS485 cable is less than 100m (the recommended length is less
than 25m).
F. Dismantle the 16-pin connector delivered with t he inverter and
set aside the water-proof plug. Route the cables through each part
sequentia lly, then connect them to Pin 6 and Pi n 7. Finally, connect
the connector to the COM1 port of the inve rter.
