• Reconnect wires to terminal block. Be sure wire colors
match labels on circuit board (B = Black, R = Red, W =
White).
To put the transducer cable in conduit, do the following:
Disconnect the cable from the terminal block and remove
the cable strain relief in the bottom of the enclosure.
Starting at the enclosure, run flexible or rigid ½" conduit to
where the transducer is located. The last few feet of conduit
adjacent to the transducer will need to be flexible. The
conduit must be well supported – NO stress can be placed
on the pressure transducer connector. Use a strain relief
bushing to seal around the pressure transducer connector.
After reconnecting the transducer wires to
CAUTION
the terminal block and ground terminal, tug
on each wire individually to ensure they are tight.
Any exposed metal in the system piping,
CAUTION
including transducer case, must be grounded
to the service entrance per NFPA 70: National Electrical
Code, Article 250.
The transducer cable has a Green ground wire and a ground
clamp supplied to facilitate grounding the transducer. See
Figure 1.
Motor Wires – See Table 2
NOTE: A MINIMUM OF 75ºC COPPER WIRE IS
MANDATORY.
Refer to the Table 2 for wire sizing and maximum wire
lengths. Charts are designed to limit voltage drop to 5%.
Insure that the wire is rated for direct burial and/or
submergence.
Figure 2 shows the terminal block where the motor and
input wires connect. The circuit board near the terminal
block is labeled to show where to connect the motor wires.
For all motors, the green wire from the motor must be
attached to the terminal labeled GND.
For 2-wire, 1Ø motors with 2 black wires, connect one
black wire to each of the terminals labeled BLK and leave
the terminal labeled X empty. It doesn't matter which black
wire goes to which BLK terminal.
For 3Ø or 3-wire, 1Ø motors with red, black and yellow
wires, connect the red wire to RED, black wire to BLK and
yellow wire to YEL.

SHOCK OR ELECTROCUTION
DANGER
HAZARD
Connect a ground wire from the service panel to the
terminal marked GND. Controller has high leakage to
ground. Controller ground terminal must be connected to
the service entrance ground terminal. Failure to do so will
result in high voltage being present on the controller chassis.
Connect two "hot" wires from the 2 pole circuit breaker to
the terminals marked L1 and L2.
The input power system used must be a grounded power
system. The voltage measured from L1 to L2 must be in the
range of 196Vac to 265Vac. The voltage measured from
L1 to GND must be equal to the voltage measured from
L2 to GND. These voltages must be within the range of
120Vac +/- 10%. Reduced input voltage will reduce system
performance.
Do not use a Ground Fault Circuit Interrupter (GFCI) with
this product or nuisance tripping will result.
