Cautions for Main Circuit Wiring
3.2.4
（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.
（2）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.
（3） Motor Wiring
◆It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components
