④
Plug the socket at one end of the extension cord into the control panel; plug the other end
firmly into the corresponding socket on the circuit board of the inverter. Cover the inverter.
3.3 Wiring of Inverter
CAUTION
1. Wiring operations for the inverter must be conducted by trained professionals.
2. The cover of the inverter must not be opened until five minutes after the power supply for the
inverter is reliably disconnected and all indicator lamps on the control panel are extinguished
3. Internal wiring operations must not commence until the high voltage indicator lamp inside the
inverter is extinguished, or the voltage between the main loop terminals (P
＋
and N
－
)
measured with a voltmeter is below 36V.
4. The enclosure of the inverter must be securely earthed; otherwise there may be an electric
shock or fire.
5. Terminals P+ and N- must not be connected with a jumper; otherwise there may be hazards of
fire or property damage.
6. The power cord must not be connected to Terminal U, V or W.
7. The inverter must be put through a withstand voltage test prior to ex-factory delivery. It is
required that no more withstand voltage tests has to be conducted; otherwise, there may be a
damage to the inverter;
8. Prior to connection to the power supply, verify that the rated input voltage of the inverter
conforms to the voltage rating of the AC power supply; otherwise there may be a personal
injury or equipment damage.
9. The main loop terminal must be securely connected to the cold-pressed terminal of the
conductor.
10. Output Terminals U, V and W must be wired in strict compliance with the phase sequence.
11. It is forbidden to connect capacitors or pressure-sensitive resistors to the output terminal of
the inverter with an attempt to absorb surges.
