Wiring
To allow for ease of wiring, the enclosure
wiring area is free of electronics other than
the terminals. Conduit holes and knockouts
are located so that the wire can be fed straight
through to the connectors, with minimal bending.
The terminals accept 6-14 AWG wire.
Installations that require larger wire gauge than
6AWG will require an external junction box. Run
6AWG wire from the Drive into the junction box,
then make external connections with wire nuts to
appropriately sized wire.
NOTICE For convenience in wiring, the input and
motor terminals unplug from the box. Pull them
down to remove them for ease of access, as
shown in Figure 8.
Verify that the terminal connectors are completely
seated when you replace them. It is best practice
to connect all output wires (larger wire gauge)
first, then all input wires.
Pump Connections
If the Pentek Intellidrive is used with above ground
motors not rated for Variable Frequency Drive
use, maximize motor life by limiting lead length
to 25 ft. Refer to the pump owner’s manual, the
National Electrical Code, and local codes for
proper wire size.
The output of the Drive is single phase (2-wire or
3-wire) or 3-phase, depending on motor selection
during startup.
The output power terminals (motor wire
connections) are located on the lower right side of
the Drive and are labeled R (Red), Y (Yellow), and
B (Black). See Tables 2 through 6 for suggested
wiresizes.
NOTICE 2-wire 1-phase connect to Y + B, not R + B.
Feed the motor cable through the 3/4” conduit
hole on the bottom right side and into the
appropriate terminals. If the wire is large enough
to require a larger conduit hole, remove the
1-1/4” knockout and use the appropriate conduit
connections. Attach the motor ground wire to the
grounding screw, located to the upper right of the
terminal block. Attach the motor power wires to
the terminals as shown in Figure 9.
NOTICE Drive does not sense motor temperature
and will not protect motor from over heating.
