2.2 Electrical Installation

Before wiring, please make sure that the input power supply is cut OFF to avoid electric

shock and fire.
To ensure safety, grounding terminals must be reliably grounded according to the

specification requirements.
Do not connect the input power supply to the U, V, and W terminals of the output by

mistake.
Please confirm whether the AC power supply is consistent with the rated input voltage of

the frequency inverter
Do not connect the electromagnetic switch and contactor to the frequency inverter input

circuit.
Before peripheral equipment is connected to the frequency inverter, it must be confirmed

that its insulation to ground is in good condition.
Do not conduct insulation withstand voltage test on the frequency inverter so as not to

damage the devices inside the machine.
