3.3 wiring notice points

(1) Assure power cut off completely for above 10 minutes before wiring, otherwise have
danger of getting electric shock.
(2) Forbid connecting power wire to output U, V, W of the inverter.
(3) There is current leakage in the inverter, for safety reason, inverter and motor must be
earthed safely, commonly use 3.5 mm
resistance smaller than 10Ω.
(4) Before shipment compression resistance test of the inverter is passed, so user should not
conduct compression resistance test again.
(5) Should not assemble electromagnetic contactor and absorbing capatance or other
absorbing device, see fig.3-3.
(6) To be convenient to over current protect of input side and power off maintenance inverter
should be connected to power supply through relay.
(7) Connecting wire for relay input and output loop(DI1~DI6、 DO1、 DO2)， should use above
