This is an industrial (Class A) product as defined by EN61326. To ensure compliance with European
Electromagnetic Compatibility (EMC) requirements for EMC emissions, please note that it is not intended for use
in domestic buildings, or in properties directly connected to an electrical supply network which also supplies
domestic buildings.
Do not connect voltages greater than specified in
interface control may be damaged.
Note: The system is protected from motor overloads and short circuits by solid state electronics. The power wiring
between the system and your electrical installation must be protected. When selecting input fuse, refer to
Table 8. Pump rating information can be found on the label on the rear of the pump.
Refer to Figure 2, item 6.
Use the following procedure and connector components supplied with the pump to connect the electrical supply to
the iXL120 system. When you make the electrical supply cable, ensure that the Earth (ground) conductor is slightly
longer than the phase conductors. This will ensure that if the cable is accidentally dragged and the strain relief bush
on the electrical supply connector mating-half fails, the Earth (ground) conductor will be the last conductor to be
pulled from the connector.
You must fit a secondary protective Earth (ground) conductor (with a cross-sectional area at least equal to phase
conductor size) to the protective Earth (ground) stud.
1. Attach the strain relief Gland (2) to the Cover Housing (3). Refer to
2. Pass a suitable cable (1) through the strain relief bush and cover. Refer to the technical data section for
information on cable sizes.
Cables must be bare ended without ferrules to ensure correct clamping in the connector block.

3. Strip back sleeving (50 mm) and insulation (10 mm) on Cable (1). Conductors must not be twisted before fitting
to Screw Module (5). Place Gasket (4) over wires
4. Before starting the assembly, use a 2mm Allen key to ensure that the axial cone in the Screw Module (5) is
screwed fully downward to completely open the contact chamber.
5. Fit conductors (3 off) to Screw Module (5) and tighten axial cone screw to 1 Nm using a 2 mm A/F hex driver.
Note: The manufacturer of the connector states that after initial assembly, the recommended tightening torque
must only be reapplied once in order to avoid damage to the individual cable strands.
6. Clip Screw Module (5) into Housing (6) so that terminal number 3 on Screw Module (5) is next to the Earth
terminal on Housing (6).
7. Connect the Earth wire of cable (1) to the Earth terminal on Housing (6).
8. Align Housing (6) with hood (3), ensure gasket (4) is in position.
9. Secure Housing (6) to hood (3) using the four screws supplied (7).
