Wiring after power off for at least 10 minutes, otherwise , an electronic short may occur.
Do not connect AC power to output terminals U, V and
W.
Both the inverter and the motor should be safety ground ed as there is leakage current inside the inverter.The diameter
of ground ing copper cable must be more than 3.5mm ² , ground ing resistor must be less than 10ohm.
W ithstand voltage test of the inverter has been done in the factory, user s would better not do it again.
Do not install electromagnetic contactor , absorption capacitor or other re sistance-capacitance absorption devices, as
shown in Fig 2 -3.
In order to make the input over - current protection and power off maint enance easily, the inverters should connect
power supply via braker .
T he connection cable of relay I/O circuit (X1~X6 , FWD , REV , OC , DO) should select the twisted-pair or shield cable
with diameter over 0.75 mm ²
.
One terminal of the shield layer should be hung in the air and the other terminal should
be connected with the inverter
’
s grounding terminal E , the cable len g th should be less than 50m .

Before layout operation, m ake sure the power supply of inverter is cut off , all the LED on the operate panel is black out
and delay for more than 10 minutes .
Before power on, please check if the power supply voltage is consistent with the inverter voltage level, otherwise
device damage , human injur ies and deaths may occur.
