Wiring c an only be done after the mains input is cut off, otherwise there will be danger of electric
shock!
Only qualified and trained engi neer can perform the wiring, otherwise there will be danger of
el ectri c shock!
Grounding cable must be grounded, otherwise t here will be danger of electric shock or fire!

Please confirm the mains vol tage level is s ame with that of the inverter, ot herwi se the inverter
may be damaged!
Make sure the ratings of the driven motor are i n compliance with the inverter, otherwi se the
motor ma y be damaged or the inverter may be in protection status !
Do not confuse the input terminals with the output terminals (U, V, W), ot herwise the re will be
danger of damaging the inverter!
Brake resistor cannot be c onnected betw een the DC bus terminals (+) and (-), otherw ise fi re
may occ ur!

The brake resist or terminal is effective only for the inve rte r of 15kW or bel ow and has a bui lt-in brake
unit . Select the recommende d re sis tor with the cable length of less than 5m, otherwi se the inverter may
burn or be damaged.
D. Inverter output U, V and W:
Inverter output terminals cannot connect t o capacit ors or surge snub devices, otherwi se the inverter may
be in protecti ve stat us or damaged.
If the cables between the motor and t he inverter are too long, el ectrical res onance may occ ur due to the
distribut ed capacitance, which may result i n damaging the motor i nsul at ion or big l eakage current, so if
the cable length is longer t han 100m, AC reactor must be i nstal led.
