5.4.2 PULSAR Motor

Connect the pump motor to the J3 terminal block labeled 'PUMP MOTOR OUT AC/DC.' (Use 14
AWG (2.1mm

), 105

C insulation wire size or larger.) The pump motor must be wired to operate at

the DLC supply voltage (i.e., if the power supplied to J1 is 115VAC 60Hz, then the motor must operate
on 115VAC at 60Hz).

If the PULSAR pump motor is controlled by a Variable Speed Drive (e.g., DC Drive), the Variable
Speed Drive must be powered by the DLC. Wire the Variable Speed Drive to J3. Wire the PULSAR
motor to the Variable Speed Drive in accordance with the Variable Speed Drive manufacturer's
instructions. Refer to Section 8 – Diagrams: Diagram 2 for recommended wiring.

If the PULSAR pump motor or Variable Speed Drive operates at a voltage different than that supplied
to the DLC or is a three-phase motor, then a motor starter must be used. Wire the motor starter relay to
J3. Wire the PULSAR motor or Variable Speed Drive to the motor starter in accordance with the
starter manufacturer's instructions. Refer to Section 8 – Diagrams: Diagram 2 for recommended
wiring.
