Control Circuit Terminal; Vfd500 Control Circuit Terminal - Danfoss VFD500 Series Manual

VFD500 high performance vector control frequency inverter user manual
of the inverter will be damaged.
◆Avoid short circuit the output cables or with the inverter enclosure, otherwise there exists the danger
of electric shock.
◆It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC noise filter with
phase lead, otherwise, the internal components of the inverter may be damaged.
◆When contactor is installed between the inverter and the motor, it is forbidden to switch on/off the
contactor during the running of the inverter, otherwise, there will be large current flowing into the
inverter, triggering the inverter protection action.
◆Length of cable between the inverter and motor
If the cable between the inverter and the motor is too long, the higher harmonic leakage current of the
output end will produce by adverse impact on the inverter and the peripheral devices. It is suggested
that when the motor cable is longer than 100m, output AC reactor be installed. Refer to the following
table for the carrier frequency setting.
