HLP-C Inverters
be connected between the motor and the output terminals
(U.V.W) of the inverter.
● The main circuit wire must be enough far away from other
control equipments.
● When the wiring between the inverter and the motor exceeds
15 meters for 230V class or 30 meters for 440V class, much
higher dV/dT will be produced inside the coil of motor, which
will cause the destroy to the interlayor insulation of motor.
Please change it to a special AC motor for the inverter or add a
reactor on the side of the inverter.
● Please lower the carrier frequency if there is longer distance
betweent the inerter and the motor. Because the higher carrier
frequency will result in the bigger leakage current of high-
order harmonics of the cables the leakage current will have
unfavorable effect on the inverter and other equipment.

b ： For control circuit wiring (signal line)
● The signal line should be separately laid in a different duct
with the main circuit wire to avoid any possible interference.
● Please use the shielded cable with the size of 0.5-2mm2 for
signal lines and make one end grounding. while the shielded
cable with the size of 1 mm² is recommended for the control
line.
● Use the control terminals correctly according to your needs.
c ： Grounding
