CONTROLLER LOCATION SELECTION
The NEMA 3R controller is intended for indoor and outdoor use
and for operation in ambient temperatures up to 125° F (50° C) .
It should be mounted in a location that provides protection from
water sprays greater than 30° from vertical . The drive should
only be accessed by trained and authorized personnel . To ensure
maximum weather protection, the unit must be mounted vertically
with the cover properly aligned and secured with all lid screws .
The following recommendations will help in selection of the
proper location of the unit:
1 .
A tank tee is recommended for mounting the tank, pressure
switch/transducer, pressure gauge, and pressure relief valve
at one junction . If a tank tee is not used, the pressure switch/
transducer should be located within 6 ft . (1 .8 meters) of
the pressure tank to minimize pressure fluctuations . There
should be no elbows between the tank and pressure switch/
transducer .
2 .
The unit should be mounted on a sturdy supporting structure
such as a wall or supporting post - please account for the
fact that the unit weighs approximately 20 lbs .
3 .
The electronics inside the controller are air-cooled . As a
result, there should be at least 6 inches of clearance on
each side and below the unit to allow room for air flow .

There are to be no elbows between the
tank and pressure switch.
4 .
The controller should only be mounted with the wiring end
oriented downward . If possible for best cooling, the controller
should not be placed in direct sunlight or other locations
subject to extreme temperatures or humidity (mounting
location should not be subjected to condensation) .
5 .
The mounting location should have access to 230V
electrical supply and to the submersible motor wiring .
6 .
Do not expose the drive to water spray greater than 30° from
vertical .
Note: Installations that require larger than 6 AWG wire will require
an external junction box . Run 6 AWG from the drive to the
junction box and make external connections to the appropriately
sized wire with wire nuts .

PUMP WIRING
If submersible pump type is chosen, the output of the drive is
3-phase . (If the option is available, 3-wire may be available for
submersible pumps) .
The power output terminals (for motor wire connections) are
located on the lower right-hand side of the controller and are
labeled RED, BLK, YEL and (W) . To select the wire size refer to
the pump owner's manual, NEC and local codes for proper wire
size .
NOTICE: Regardless of owner's manual, wire length should not
exceed 1000 ft .
If the Commander Pro Controller is used with above ground
motors the output is limited to 3-phase . To maximize motor life
the cable length between the controller and the motor should
be limited to a maximum length of 25 ft . Caution: Correct motor
rotating needs to be verified to avoid pump and motor damage .
Due to the inherent voltage changing
characteristics of variable frequency drives (VFD), there
is additional stress placed on the insulation of the wire
between the controller and the motor compared to a
standard pump system. Extra care must be taken when
using Un-jacketed Flat Parallel Pump Cable to ensure that
the insulation on each of the separated wires is the same
thickness. Care must also be taken to ensure a proper seal
with shrink tubing on any splices. Failure to take these
precautions can lead to "wire burn through" that will shut
down the system. Under these circumstances, no permanent
damage usually occurs to the controller or motor. For further
details call Technical Support at
