1.1.
SDM630-Modbus V3 is a multi-function rail meter, it can accurately measure and display various power parameters in 1P2W/3P3W/3P4W:
voltage, current, power, frequency, active power, reactive power, forward power, reverse power, total harmonics, etc. The meter is suitable
for real-time power monitoring system, with multi-function, multi-purpose, high stability and long life characteristics. The meter is connected
with an external current transformer and is suitable for various high and low voltage power grids. The meter has RS485 communication
interface, supports the highest communication rate of 38400bps, can realize remote communication.

Installation
a.The network cable is described as follows:
b.Cut the crystal head, find out PIN1 and PIN5, and connect the
communication terminals according to the picture.
c.Connect the communication terminals as shown.
d.Connect the communication terminals to the 30-pin
communication terminals of the inverter.
e.The standard RS485 cable length is 15m.If need longer RS485
cable,please use an ethernet coupler to extend and make sure
RS485 cable less than 100m(the recommended length is less than
25m).
f.MOD XH system application block diagram wiring is as follows.

Button Definition And Display
There are four touch buttons on the panel, from top to bottom are “ESC(←)V/A”, “↑(Alt)MD/PH/HZ”, “↓(Shift)P”, “ENTER(→)E”. There are
two types of key operation: long press(Press for more than two seconds) and short press(Pressing time is less than one second).
