WARNING
Measure and verify site voltage phase to phase and
phase to ground prior to connected power to the
controller.
NOTE
Verify that there is at least 8” between input and
output connections or input connections and control
wiring.
DANGER
The controller has a high leakage
current to ground. The input terminals
marked “GND” must be directly
connected to the service entrance ground. Failure to
properly ground the controller or motor will create
an electrical shock hazard.
NOTE
Do not use GFCI protection with this controller.
Nuisance tripping will result.
NOTE
A single phase power input is designated only on
230 V specifically, and the corresponding SPD Plus
pump controllers are derated to 50%.
DANGER
Status Code Indicator Light and Control
Panel Display are not voltage indicators!
Always turn off disconnect switch and
wait 5 minutes before servicing.
DANGER
The controller will remain electrically
charged for 5 minutes after power
is turned off. Wait 5 minutes after
disconnecting power before opening controller
access cover as there is a severe shock hazard.
OUTPUT POWER CONNECTIONS
Ensure input power disconnect is locked
in the off position before making the
output power connections. Run the motor
lead wire from the motor or conduit box through
metal conduit to the bottom of the controller. Use
metal conduit and metal conduit connectors. Size
the conduits according to the NEC, CEC or local
codes. Connect conduit and insert the wires through
the bottom of the enclosure or controller conduit
box extension. For frames N4, N5 and N6, it may be
necessary to drill a hole in the bottom of the enclosure
for conduit and wire entry.
Consult motor manual to determine the wire size for
the application. Ensure the ground connection to
the motor is continuous. Connect wires to the output
terminal block on the controller labeled U2, V2, W2,
and GND. Connect the ground wire to the terminal
labeled GND.
If a reactor is used for a submersible motor, connect
drive output terminal block U2, V2, W2 and GND to
the corresponding input terminals of the load reactor.
Connect the output terminals of the reactor to the
motor leads and GND. When wiring the load reactor
ensure all input connections from the controller are on
the same side of the reactor terminal block.
NOTE
A load reactor or load filter is required in installations
where the output motor leads exceed 50 ft.
NOTE
It is recommended to use a load reactor with all 575V
installations.
NOTE
Models with ‘F’ suffix include a load reactor prewired
to the controller.
NOTE
Ensure you have a three phase motor and verify
the motor voltage matches input power supply
voltage. Verify that the motor service factor amps
do not exceed the drive output at rated ambient
temperature. Ensure the ground is continuous
between the controller and the motor. Ensure there
is at least 8" between the output wires and any other
wires.
For CentriPro motors, connecting U2 to Red, V2 to
Black and W2 to Yellow will give the correct rotation.
To change rotation, swap any two motor leads U2, V2
or W2.
Motor power and type are to be specified in Start-Up
Menu on drive keypad before running pump system.
DANGER
The controller has high leakage current
to ground. The output terminals
marked “GND” or “ ” must be directly
connected to the motor ground. Failure to properly
ground the controller or motor will create
an electrical shock hazard.
