9. OPERATION

VFD is configured according to the motor requirement.

Close the safety cover properly and check that all cable
glands are firmly tightened.

Ensure that input power to the unit is off and locked out.
Do no rely on the drive disconnect switches for input
power isolation.

Verify that there is no voltage on input terminals L1
(91), L2 (92), and L3 (93), phase-to-phase, and phase-to-
ground.

Verify that there is no voltage on output terminals 96 (U),
97 (V), and 98 (W), phase-to-phase, and phase-to-ground.

Confirm continuity of the motor by measuring Ω values
on U–V (96–97), V–W (97–98), and W–U (98–96).

Check for proper grounding of the drive and the motor.

Inspect the drive for loose connections on the terminals.

Confirm that the supply voltage matches the voltage of
the drive and the motor.

Always flush the pump with a solvent compatible with
the material being pumped if the material being pumped
is subject to “setting up” when not in use for a period of
time.

The outlet material volume is governed not only by the
Fluid pressure but also by the material supply available
at the inlet. The material supply tubing should not be too
small or restrictive. Be sure not to use hose which might
collapse.

Secure the pump legs and bolted to a suitable surface
(concrete floor) to ensure against damage by vibration.

If this Pump is used for prolonged operation at low speed
ensure there is enough ventilation around the motor to
cool it efficiently.

Set the desired frequency on the VFD.

Press the start (run) button on the VFD.
