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 2 and Table 3 list the full load motor currents at various voltages.
* Only available on pump model X3862-64000.
Single Phase Motor Connection
The pump can be configured for low voltage or for high voltage. As supplied from the factory, the pump is configured for
low 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 11) 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.
❑
A 1/2

14 NPSM hole is also provided next to the

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.
