Mains Supply Cable Connection - Edwards iXH100 Instruction Manual

3.7.1

Mains supply cable connection

The Harting connector is not approved for connection and disconnection under load.
If you need further information on connecting the electrical supply, contact Edwards for advice.
Three different types of electrical supply connector are used on these pumping systems. Refer to
details of the connector types and the systems to which they are fitted. Some pump variants are supplied with the
appropriate parts needed to make up the mating half of the electrical connector
available as an accessory, refer to
connector for your system and follow these instructions to make your electrical supply cable:
1. Screw the strain relief bush onto the connector outer cover.
2. Pass a suitable cable through the strain relief bush and cover. Refer to
type. Cables must be bare-ended without ferrules to ensure correct clamping in the connector block.
3. Before starting the assembly, use the hex (Allen) key specified in the appropriate figure to ensure that the axial
cone is screwed fully downward to completely open the contact chamber.
4. Carefully remove the cable insulation to the exact dimension specified in the appropriate figure. Do not twist
the cable strands.
5. Referring to the appropriate figure to identify the connections, insert each wire completely into the contact
chamber until the copper strands reach the bottom. Keep the cable in position while applying the recommended
tightening torque.
6. Fit the earth (ground) wire to the Protective Earth connection as shown in the appropriate figure.
Note: The Protective Earth connection on the Han
to use one of the cable shoes (provided in the connector kit) to fit the protective earth (ground) wire. The
cable shoe provided for the 380 - 460V systems is intended for 16 mm
includes cable shoe options for 16mm
solution for the size of cable that you are using.
7. If coding pins are supplied, fit them to the connector block according to voltage variant as shown in the
appropriate figure.
8. Refit the outer cover to the connector block then tighten the strain relief bush.
Note: Harting (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.
9. The pumping system has an electrical connector locking mechanism
a suitable screwdriver to release. Refer to
(item 5) fitted and the locking mechanism (item 1) may be applied. Follow these instructions to fit your
electrical supply cable.
Slacken off the locking screw (item 3) by a few turns to loosen the locking mechanism if necessary.

Move the locking mechanism (item 1) to the left as far as possible, then lift it up so that it rotates around the

pivot screw (item 2) and clears the left hand lever (item 4).
Push back both levers (item 4) to release the protective cover.

Remove the protective cover and fit your electrical supply cable.

Pull both levers back towards you to lock your electrical supply cable connector in place.

Push the locking mechanism down as far as possible and then push to the right so that it prevents the left

hand lever from actuating.
