Pentair Pentek Solar Drive Wiring Instructions
Figure 7: Wiring Inside the Pentair Pentek Solar Drive
Once the system is wired (per Figure 7), the power conductors wired to the terminals blocks
inside the Pentair Pentek Solar Drive should be tightened with torque values of:
– Power solar PV and motor load conductors: 10 lb-in
– Float switch signal conductors: 8 lb-in
The cable glands (cord grips) on the bottom of the enclosure should be used as shown on
Figure 7 below. Solar power wires feed through the right gland, float switch/signal wires
feed through the middle gland, and motor load wires feed through the left gland.
When all conductors are wired into the controller, the cover (door) should be replaced and
tightened using the cover screws to 2-3 in-lb or equivalent.
WARNING
Do not ground the positive or negative leads of the PV modules!
Only ground the mounting frames of the PV modules.
Never run the Pentair Pentek Solar Drive controller when the AC pump is not connected!
It might cause damage to the controller.
If an installed 3-phase pump does not start pumping water, switch the positions of any
two of the three motor wires.
It will change the direction of rotation and it should start
pumping water!
