Danger

3.6.4 Steps for electrical connection

If the inverter has been electrified and tested before

connection, wiring can not be performed unless the AC and

DC power supplies are cut off for 10min and a multimeter

shows that the DC side is tatally discharged.

Please cover the PV array by lightproof material or switch

off the DC circuit breaker before electrical connection. A

dangerous voltage will be generated by the PV array

exposed in the shine.
