Pentair Pentek Solar Drive Installation Requirements
Once the Pentair Pentek Solar Drive is installed in a shaded location (see Figure 3), it can be wired to DC
(solar) sources. Maximum cable lengths for 115 and 230Vac for different motor load currents are shown in
Figure 2 below.
This unit was evaluated for temperature rating of 60/75°C (140/167˚F) on power field wiring terminals.

Dimensions of the Pentair Pentek Solar Drive and back panel are shown in Figure 4, with additional
details on how to mount the unit on page 7.
The Pentair Pentek Solar Drive must be installed in a shaded location, away from any source of heat
and in an area free of vegetation. Measures must also be made to protect the unit from damage by
unauthorized persons, large animals, overgrowth, flooding, or other harm.
WARNING
The Pentair Pentek Solar Drive has voltages capable of causing severe injury or death by electrical
shock. It should only be installed and serviced by Pentair authorized suppliers, dealers and installers.
– Contact your Pentair Supplier/Dealer for any service or warranty claims
– NEC codes take precedence over suggestions in this manual
– We strongly recommend that the installation data be recorded into the “Installation Notes” section
on page 14 and that the manual is stored near the unit
The Pentair Pentek Solar Drive should be mounted at least 2 feet (60cm) above the ground when possible.
A minimum of 10 inches (25cm) of clearance above the Pentair Pentek Solar Drive is required for internal
access. There must be no obstruction of air flow to the heat sink. A typical installation on an array
structure is shown in Figure 3, below.
