between “DC+” and “DC-” of DC wiring terminals of the inverter and ensure that it is within
normal voltage range. Otherwise, turn off DC breaker D1 and recheck the wiring in DC port.
(2) Turn off DC breaker D1, turn on AC breaker D3, measure the voltage among “A”, “B”,
“C” and “N” of AC wiring terminals of the inverter. If it is 3-phase and 3-wire connection, the
voltage between A-B, B-C and C-A should be 400/380V. If it is 3-phase and 4-wire
connection, the voltage among A-N, B-N and C-N should be 230/220V. If the measurement
deviation is higher than tolerance, turn off AC breaker D3 and recheck the wiring in AC port.
CAUTION
The neutral line of the load MUST be connected to the grid's neutral
line even if the PWS2-30M-EX is implemented as backup power.
DANGER
Electrical connection inspection needs to be completed by qualified
operator.
After the switch is closed, the system has been loaded with high
voltage, so contact with any bared electrical part in the inverter is
prohibited.
WARNING
Only qualified professional can operate.
