ST-4125D/ST-6125D — 230/460 VAC VOLTAGE SELECTION

230/460VACVoltage Selection

The ST-4125D/ST-6125D submersible pump is factory set at 230 VAC. To change the voltage from 230 VAC to 460 VAC, perform the following (refer to Figure 5):

1.Place pump in a suitable area free of dirt and debris.

2.Remove the four retaining screws, using a 19 mm socket, and the two Allen screws using an 8 mm socket, that secure the pump casing.

3.Lift the top of the pump by attaching a chain on the eye bolts and using a crane or similar equipment. Be careful not to fully stretch the cable connections inside the pump.

4.Cut the tie-wrap holding the 460 VAC motor winding wires as shown in Figure 5.Then remove the protective covering from the wires (labeled 4, 5, and 6).

5.Remove the sleeving covering the large red wire and separate the 2 wires labeled 1 and 7.

6.Connect the wire labeled 4 from step 4 to the wire labeled 7 from step 5 and join them with the large red wire. Cover the wires with sleeving.

7.Repeat steps 5 and 6 for the large black wire and the large white wire. Refer to the table in Figure 5 for wires to separate (column 2) and wires to connect (column 4).

8.Using electrical tape, bind the 3 wires that were separated and disconnected (labeled 1, 2, and 3). Place these wires neatly inside the housing.

9.Reinstall the top of the pump and reinsert the six screws and tighten securely.
