2. N700E VFD Set Up
In order to operate N700E VFD, it has to be wired properly to the power supply and the motor. Often
accessory units are used for performance enhancement. Then, the VFD needs to be configured of how to
be operated, where the start/stop command and frequency command source comes from. This
configuration is done by programming parameters with selected values. The overall setting of N700E is
discussed in this chapter.

2.1 Wiring
Failure to comply with the following could result in electrical shock, fire, or other harm to
personnel or machinery.
Be sure to ground the unit.
Wiring work should be carried out by qualified electricians.
Implement wiring after checking that the power supply is off.
After mounting the VFD, carry out wiring.
Do not remove the rubber bushings where wiring connections are made.
(5.5 kW (7.5 HP) to 22kW (30HP)) Due to the possibility that a wire may be
damaged, shorted or may have a ground fault with the edge of the wiring cover.
Failure to comply with the following could result in electrical shock, fire, or other harm to
personnel or machinery.
Make sure that the input voltage is:
200 to 240V +/- 10%, 50/60Hz
(Model : N700E-055LF/075LFP~750LF/900LFP)
380 to 480V +/- 10%, 50/60Hz
(Model : N700E-055HF/075HFP~3500HF/3800HFP)
For single phase input applications, de-rating of the VFD will be required for safe
and reliable operation. Please contact WorldWide Electric Corporation for sizing
assistance and proper VFD selection. When wiring input power, be sure to
connect to input terminals (R, T)
Be sure not to connect AC power supply to the output terminals (U, V, W).
Be sure not to connect a resistor to the DC terminals (PD, P) directly.
Be sure to use an earth leakage breaker or fuses on input supply to the VFD.
As for motor leads, earth leakage breaker or electromagnetic contactors should
not be used unless consulting with WorldWide Electric.
Do not use the electromagnetic contactors on the primary side of the VFD as
means of start/stop control.
