1. A tank tee is recommended for mounting the tank,
pressure sensor, pressure gauge, and pressure relief
valve at one junction. If a tank tee is not used, the
pressure sensor should relocated within 6 ft. (1.8
meters) of the pressure tank to minimize pressure
fluctuations. There should be no elbows between the
tank and pressure sensor.
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 17 lbs. for NEMA 1 models and 22.0
lbs. for NEMA 4 models.
3. The electronics inside the CP WATER SD100 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 should be at least 6 inches of
clearance on each side and below the unit to allow
room for proper air flow. There are to be no elbows
between the tank and pressure switch.
4. The CP WATER SD 100 should only be mounted
with the wiring end oriented downward. 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
freezing conditions or condensation).
5. The mounting location should have access to 230V
electrical supply and to the submersible motor wiring.
WIRE SIZING
Maximum wire lengths connecting the CP100 controller
to the main circuit box. (Based on 3% voltage drop at
230V)
Copper Wire Size (AWG) 12* 10 8 6 4 3 2
Maximum Length (Feet) 85 140 220 345 550 680 895
*Wire with 90° C insulation only.
Maximum wire lengths connecting the motor to
the CP100 controller
Copper Wire Size (AWG) 14 12 10 8 6
Maximum Length (Feet) 320 510 810 1280 2010
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 Unjacketed 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.

SEPARATED WIRE
IL0837
1. NOTE: DO NOT USE ALUMINUM WIRE.
2. Use 20 Amp circuit breaker for 230V supply
Controller Installation Procedure - SD100
1. Disconnect electrical power at the main breaker
2. Drain the system (if applicable)
3. Install pressure sensor - the pressure sensor has a
1/4 - 18 National Pipe Thread (NPT) connection.
4. Remove the CP WATER SD100 cover by removing
the three lid screws. Install the unit to the wall using
three mounting screws (not included).
Wiring Connections
1. Verify that the power has been shut off at the main
breaker.
2. Verify that the dedicated branch circuit for the CP
WATER SD100 is equipped with a 20 AMP circuit
breaker.
3. Remove the CP WATER SD100 lid.
4. Feed the motor leads through the opening on the
bottom right side of the unit and connect them to the
terminal block positions marked (green ground wire),
Red (Black) Yellow (Brown) and Black (Blue)
5. Feed the 230V power leads through the larger
opening on the bottom left side of the CP WATER
SD100 controller and connect them to the terminals
marked L1, GND, and L2 .
6. Feed the pressure sensor leads through the smaller
opening on the bottom left side of the CP WATER
SD100 unit and connect the red and black leads to
the terminals marked “1” and “2” (interchangeable)
with a small screwdriver (provided).
7. Use the appropriate strain relief or conduit
connectors.
