3.6.1

Connect to 3-phase pumps

1. Remove the motor terminal-box cover.

2. Check your electrical supply voltage and frequency. The universal motor of the pump can

be configured for ‘low-voltage’ operation (200-230 V) as shown in Figure 5, or for
’high-voltage’ operation (380-460 V), as shown in Figure 6. If necessary, reconfigure the
motor to operate with your supply voltage.

3. Fit a suitable 20 mm cable-gland to the cable leadthrough hole. If your cable is too large to

pass through a 20 mm cable-gland, fit a 20 mm to 25 mm female thread adaptor to the cable
entry-hole, and fit a 20 mm cable-gland to the adaptor.

4. Pass the electrical supply cable through the cable-gland.

5. Connect the phase wires in the cable (L1, L2, L3) to the U, V and W terminals as shown in

Figures 5 or 6, depending on your electrical supply voltage, then connect the earth wire in
the cable to the earth stud in the terminal-box.

6. Tighten the cable-gland and replace the terminal-box cover.

7. Connect the wires at the other end of the cable to your electrical supply.

3.6.2

Connect to 1-phase pumps

1. Remove the motor terminal-box cover.

2. Check your electrical supply voltage and frequency. The universal motor of the pump can

be configured for ‘low-voltage’ operation (100-115 V) as shown in Figure 7, or for
’high-voltage’ operation (200-230 V), as shown in Figure 8. If necessary, reconfigure the
motor to operate with your supply voltage.

3. Fit a suitable 20 mm cable-gland to the cable leadthrough hole. If your cable is too large to

pass through a 20 mm cable-gland, fit a 20 mm to 25 mm female thread adaptor to the cable
entry-hole, and fit a 20 mm cable-gland to the adaptor.

4. Pass the electrical supply cable through the cable-gland.

5. Connect the neutral and live wires in the cable (N, L) to the X and Z terminals as shown in

Figures 7 or 8, depending on your electrical supply voltage, then connect the earth wire in
the cable to the earth stud in the terminal-box.

6. Tighten the cable-gland.

7. Connect the wires at the other end of the cable to your electrical supply.
