5. Feed the motor supply cable and 230 VAC power leads
through the bottom right and left strain reliefs respectively.
Connect the motor ground and power supply ground wires
the terminal block marked GND and PE respectively.
!
Because of the leakage current produced
by the internal filtering, permanent fixed ground connections
must be made using two independent conductors each with a
cross-section equal to or exceeding that of the supply conduc-
tors. The drive is provided with two ground terminals marked
PE to facilitate this.
6. Connect motor supply leads to terminal block positions
marked U, V and W (right hand side). Connect power leads
to terminals marked L1 and L3 (left hand side).
Note: For correct motor rotation and pump performance on
F&W manufactured motors, leads 1-7, 2-8 & 3-9 on the motor
should be connected to U, V & W respectively. Three phase
motors from other manufactures may require that connection
U & V be switched at the drive for proper motor rotation and
performance.

7. Feed the pressure sensor leads through the smaller strain
relief on the bottom of the Artesian Drive unit and connect
the red and black leads to the terminals marked “B2” and
“B5” (interchangeable) with a small screwdriver (provided).
Make sure to not disconnect the factory installed jumper
wire that is already connected to terminal “B2”.
NOTE: A 10-foot section of pressure sensor cable is provided
with the controller, but it is possible to use similar 20 AWG
wire for distances up to 100 feet from the pressure sensor.
8. Slide the lower enclosure cover into position and tighten
screw on bottom lip as show.

as shown; do not press fully into position. Replace the front
cover. Do not over-tighten the screw.

10. Connect the other end of the pressure sensor cable with the
two spade terminals to the pressure sensor. The connections
are interchangeable.
11. Set the pressure tank pre-charge at 70% of the desired
water pressure setting. To check the tank’s pre-charge, de-
pressurize the water system by opening a tap. Measure the
tank pre-charge with a pressure gauge at its inflation valve
and make the necessary adjustments.
12. The pressure sensor communicates the system pressure to
the Artesian Drive controller. The sensor is preset at the
factory to 50 psi, but can be adjusted by the installer using
