4. Main Circuit Terminals and Wiring

Danger
★
Wiring can only be done after the mains input is cut off, otherwise there will be danger of electric
shock!
★
O nly qualified and trained engineer can perform the wiring, otherwise there will be danger of
elect ric shock!
★
G rounding cable must be grounded, otherwise there will be danger of electri c shock or fire!
Danger
★
Please confi rm the mains volta ge level is same with that of the inverter, otherwise the inverter
may be damaged!
★
Make sure the ratings of the driven motor are in compliance with the inverter, otherwise the
motor may be damaged or the inverter may be in protection status!
★
Do not confuse the input terminals with the output terminals (U, V, W), otherwise there will be
danger of damaging the inverter!
★
Brake resistor cannot be conne cted between the DC bus terminals (+) and (-), otherwise fire
may occur!

2 ） N ot e s o n Wi r i ng
A. Input power supply L and N or R, S and T:
There is no phase-ration requirement for the input of inverter.
B. DC bus (DC+) and (DC-) terminals:
Pay attention that the DC bus terminals (DC+) and (DC-) still have voltage after power off, and the user can
only touch the terminals after the CHARGE LED turns off and the voltage is below 36V, otherwise
there is a danger of electric shock.
When selecting the brake unit for the inverter above 18.5kW,pay attention that the polarity of (DC+) and (DC-)
cannot be reverse, otherwise the inverter may burn or be damaged. The cable length of brake unit shall
be less than 10m and twisted pair cables shall be used.
Do not connect the brake resistor directly to the DC bus, otherwise the inverter may burn or be
damaged.
