Electrical Connections

Wire the motor and electrical interlocks (if applicable) in accordance with local electrical codes and the relevant electrical
component manufacturer's instructions. Table 18 lists the full load motor currents at various voltages.

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 14 gage cable.

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 electri-
cal 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
the three (3) screws removed in step 2.
