SD1500 Manual

Note
Please select one unit to be Master unit.
Use the cables to connect Master and Slave units.
The CAN1 and CAN2 port connection please refer to Figure 25.
Note
The simple method to determine the terminal resistor：No need to set the
terminal resistor when CAN1 and CAN2 port have wiring.
Note
SD series can be used for N+1 (N≦14) redundancy and the ability of
enlarge the capacity (Users can install maximum 15 units of inverters
together in parallel in order to provide the power expansion).
3. Before using the parallel function, you need to set voltage and frequency of all
units’ DIP switches to the same selection (refer to section 3-3).
4. Check RJ-45 line connects already.
5. SD series based on master-slave architecture and support auto master function.
User only set one SD parameters and other SDs will follow the master SD
setting.

Drawing
The SD series create 1Ф3W
power system, L1-L2 Voltage
is L1-N double.
Example
Example：
SD2500-124 set output 100V /
50Hz
The L-N：100V / 50Hz
Example：
SD2500-124 set output 100V /
50Hz
The L1-N：100V / 50Hz
Example：
SD2500-124 set output 100V /
50Hz
The phase voltage is 100V /
50Hz (L1-N, L2-N, L3-N)
The line voltage：L1-L2, L1-L3,
L2-L3 ~ 173V/50Hz
