INSTALLATION
7. Tighten the cable-gland nut strain-relief screws.
8. Fit a suitable cable-gland and nut to the second gland entry hole, then pass the thermistor control cable through
the gland and tighten the gland. The cable-gland must be rated to provide seal protection of IP55 (in IEC 529) or
better to the terminal-box.
9. Connect thermistor terminals X1 and X2 to wires passed through the second cable gland.
10. Connect the thermistor wires to a suitable control circuit.
11. Refit the terminal-box cover.
3.6.3 Connect the electrical supply to the pump-motor (230/460 V, 60 Hz electrical
supplies)
Make the wiring connections to the pump-motor in accordance with the US National Electrical Code and with
approved local and site practices.
Connect the electrical supply from the contactor to the pump-motor as described below.
Refer to Figure 5 . Note that the GV260 and GV410 and GV600 230/460 V 60Hz pumps may be supplied either with the
motor wires (3) fitted to a terminal block (4) or with the terminal wires (3) unterminated. If the pump is supplied
with the motor wires unterminated, use a suitable, secure method to link the motor wires and to connect the phase
wires of your electrical supply cable; we recommend that you fit a terminal block as shown in
Figure 5 . The following
procedure assumes that you have fitted a terminal block to the motor wires.
1. Remove the cover from the pump-motor terminal-box ( Figure 1 , item 17).
2. Either use the cable glands supplied if acceptable for your cable and proceed to step 4, or fit your own glands as
described in step 3 below.
3. Fit a suitable cable-gland and nut to the entry hole, then pass the supply cable through the cable-gland and
tighten the cable-gland. The cable-gland you use must be rated to provide seal protection of IP55 (in IEC 529) or
better to the terminal-box
4. Refer to Figure 5 . Ensure that the links (6) are correctly configured for your electrical supply voltage; note that
the links required are shown in Table 5 :
5. Tighten the cable-gland nut strain-relief screws and refit the terminal-box cover.

For a 230 V electrical supply, configure the links as shown in detail A.

For a 460 V electrical supply, configure the links as shown in detail B.
WARNING
Connect the phase conductors (L1, L2 and L3) of the supply cable (1) to terminals TI, T2 and T3.
WARNING
Ensure all power supplies are Isolated before commencing work.
