Single Phase Motor Connection
The pump can be configured for low voltage, 100 VAC to 115 VAC, or for high voltage, 200 VAC to 230 VAC. Low voltage
exists between connection points "4" and "Line 2" whether the pump motor is configured for low or high voltage. Figure 4
shows the electrical connections for a single phase motor.

1. Verify the electrical supply voltage.
2. Remove the three screws (item 12 in Figure 3 on
page 35) that are holding the motor electrical cover
(item 13 in Figure 3).
3. Refer to Figure 4 to connect the motor to match your
supply voltage.
Two options are available to strain relieve the
electrical supply cable.
❑
The cable can be mechanically held under
the electrical cover in the groove provided.
The groove is sized for a 14 gage cable.
❑
A 1/2-14 NPSM hole is also provided next to
the motor cover.

4. Wire L1 and L2 per Figure 4 using right angle flag
connectors or ring connectors.
Ensure that no exposed wiring is close to the
electrical cover or to other terminals on the board.
5. Secure the ground wire under the ground screw using
a ring connector.
6. Replace the motor electrical cover and secure it with
three (3) screws removed in step 2.
