Cautions for Main Circuit Wiring
(
1
)
Power Supply Wiring
◆
It is forbidden to connect the power cable to the output terminal of the inverter. Otherwise, the internal
components of the inverter will be damaged.
◆
In order to provide input side overcurrent protection and power outage overhaul convenience, the inverter should
be connected to the power supply through circuit breakers and contactors.
◆
Please confirm the power phase, the voltage is consistent with the product nameplate, do not match may result
in damage to the inverter.

)
DC wiring
◆
Do not connect the braking resistor directly to +, -, which may cause the inverter to be damaged or
even fire.
◆
When using the external brake unit, pay attention to +, - can not be reversed, otherwise it will cause
damage to the inverter and brake unit or even cause a fire.

Motor Wiring
◆
It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components
of the inverter will be damaged.
