Note:
For the cable selection for model IP54, see the cables applicable to the models with the
same power as model IP54 in this table.
It is appropriate to use the recommended cable size under 40°C and rated current. The
wiring distance should be no more than 100m.
If the control cable and power cable must cross, the angle between them must be 90°.
If the inside of the inverter is moist, the insulation resistance will decrease. If there is
moisture in the inverter, dry up the inverter and measure the humidity again.
A.4 Reactors
If the distance between the inverter and the motor is longer than 50m, frequent overcurrent
protection may occur to the inverter because of high leakage current caused by parasitic
capacitance effects from the long cables to the ground. In order to avoid the damage of the
motor insulation, it is necessary to add reactor compensation. If the distance between the
inverter and motor is 50~100m, see the table below for model selection; if it exceeds 100m,
consult with INVT technical support.
