Installation
step 3. Connect the Cb Panel to the VFD
Figure 4.
NOTE: Do not wire to a sub-panel - only to the main
breaker panel.
1. Ground the VFD back to the building's own ground
(that is, to the system ground from the CB panel, going
to the system ground rod).
2. Use a dedicated 230V branch circuit directly from the
main CB panel:
15 amp CB for Model PPC7-1-7A3.
30 amp CB for Model PPC7-1-13A2.
3. Power must be off at the main circuit breaker.
4. Remove the Control cover and clean out the box: NO
OFFCUTS or debris should be left in the box!
5. Feed the wires through the appropriate conduit hubs
and into the VFD. Connect them to the terminal blocks
as shown in Figure 4. To maintain the NEMA 3R rating
on Models PPC7-1-7A3-3-A and PPC7-1-13A2-3-A, all
wiring for these models must be run to the VFD in
liquid-tight conduit with liquid-tight conduit connectors.
NOTE: Either add terminals to the input cables (as
shown), or make a wire loop in the input cables prior to
tightening the terminal screw.
6. Tighten the terminals to the torque specifications shown
below.
• Input/output power terminals: 13 in-lbs.
• Transducer Cable terminals: 5 in-lbs.
7. All wiring must comply with NEC or CEC and all local
codes, as applicable.
step 4. Connect the VFD to the motor
1.
Figure 5.
Connect the motor leads in the order as shown.
NOTE: Connecting the wires in the wrong order may
damage either the motor or the drive and will void the
warranty.
2. Connect the motor ground to the inverter's grounding
terminal as shown.
3. Ground the motor to the well head.
4. Bundle the ground and motor wires
5. All wiring must comply with NEC or CEC and all local
codes, as applicable.
step 5. Connect Transducer Cable and set Parameters
Figure 6.
1. Connect the Transducer Cable as shown. Note the
color coding of the wires.
2. Do not disturb the factory installed jumpers.
3A. 3/4, 1, and 2 HP Controls: See "SETTING
PARAMATERS", Page 7, then return to Step 4, below.
3B. 1/2 and 1-1/2 HP Controls: Go to Step 4, below.
4. Install the box cover. Be sure that all tabs are in the slots
and secure the cover with the mounting screw (NEMA 1
models) or knob (NEMA 3R models) at the front.
5. Turn on the power to the VFD.
