Power Supply Cable
• Do not connect the input power to U, V, W terminals of MONT20.
• Do not connect the phase-shifting capacitors to the output circuit.
• Be sure the AC input power supply voltage is the same as rated input current of MONT20.
Refer to page 7 for the selection of power supply cable.
Motor Cable
Refer to page 7 for the selection of motor cable.
The longer motor cable is, the higher frequency leakage current will be, causing higher harmonic
output current to increase. This may affect peripheral devices.
Control Cable
To reduce the interference and attenuation of control signal, length of control cable should be limited
to 50m.
The control cable must be shielded cable. The analog signal cable must be shielded twisted pair.
Shielded cable should use high frequency low impedance shielded cable. For example: Copper net,
aluminum net or iron net.
