6. Absolutely prohibit the connection of power supply wire and output terminal
Don’t connect the input power line to the output terminal.
If you input the power at the output terminal, the internal components of inverter
will be damaged.
7. Absolute prohibit short-circuit or grounding of output terminal
Do not directly touch the output terminal. Do not short the output line with inverter
housing. Otherwise, there will be danger of electric shock and short circuit.
In addition, don’t short the output line.
8. Absolutely prohibit the use of phase-shift capacitor
Don’t connect the capacitor in the output circuit. It will cause the damage of the
inverter.
9. Absolutely prohibit the use of electromagnetic switch
Don’t connect electromagnetic switches and electromagnetic contactors.
Otherwise, inverter surge current will cause protection action, and that will damage
interial components when it’s serious.
10. Wiring distance between inverter and motor
The longer wiring distance between the inverter and the motor, the higher high-
harmonic leakage current of the cable.
Leakage current will negatively impack the inverter and near equipments. Then it
should minimize the leakage current.
Wiring distance and carrier frequency are as shown in Table 3-3:

11. Ground connection
①
Ground terminal, please connect the ground.
220V series
:
type 3 ground
(
grounding resistance is less than 100Ω
)
380V series
:
special type 3 ground
(
grounding resistance is less than 10Ω
)
②
Don’t share the grounding line with welding machines or power equipments.
③
Please use the grounding wire according to electrical equipments technical
standards. And the distance from the ground is as short as possible.
