Mains Supply Cable Connection; High And Low Voltage Coding Pin Arrangement - Edwards iXL600 Instruction Manual

A540-55-880 Issue D
Section 2.5.
Note: Pump rating information can be found on the label on the rear of the pump.
If connecting the electrical supply to the system through an ELCB (or RCD depending on territory) it must be suitable
for protection of equipment with a d.c. component in the fault current, and suitable for short-duration, switch-on
surges, and for high-leakage current (for example, type B, according to EN50178).
The secondary protective earth (ground) is required in case of failure of the primary earth and because pump filters
can cause high earth leakage currents, refer to
3.7.1

Mains supply cable connection

The mains connector is not approved for connection and disconnection under load.
Use the following procedure (refer to
connector supplied with the pump. If using a different connector to that supplied, follow the manufacturer's
instructions. When making the electrical supply cable, ensure that the earth (ground) conductor is 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.
If further information on connecting the electrical supply is required, contact Edwards for advice.
1. Screw the cable gland onto the connector hood.
2. Pass a suitable cable through the cable gland and hood. The cross sectional area of the cable wires should be 6
2
mm . Cables must be bare ended without ferrules to ensure correct clamping in the connector block.
3. Fit the coding pins to the connector block according to the branch supply voltage as shown in
supply is Low Volts, 400 V supply is High Volts.
4. Before starting the assembly, use the hex (Allen) key as shown in
screwed fully anticlockwise to completely open the contact chamber.
