Mains Supply Cable Connection - Edwards GXS Series Instruction Manual

To use the dry pumping system with a power supply in a different voltage range to that
specified on the rating plate, contact us.
The dry pumping system is protected from motor overloads and short circuits by
solid‑state electronics. The power wiring between the dry pumping system and the
electrical installation must be protected. When selecting input fuses, refer to
data on page 20. Pump rating information can be found on the label on the rear of the
pump.
To connect the electrical supply to the dry pumping 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, for short duration switch‑on surges and high leakage
current (for example, type B, according to EN50178).
The secondary protective earth (ground) is required in case of a failure of the primary
earth and because pump filters can cause high earth leakage currents. Refer to
General electrical

3.6.1 Mains supply cable connection

WARNING:
The Harting connector is not approved for connection and disconnection under load.
Three different types of electrical supply connector are used on the dry pumping
systems. A kit of parts containing the correct mating half connector is supplied with each
dry pumping system. Refer to
types and the dry pumping systems to which they are fitted. Information for wiring each
of these different connectors is given in:
▪ Figure: The Harting Han® K 4/4 cable-mounted connector
▪ Figure: The Harting Han® 100A axial screw module cable-mounted connector
▪ Figure: Customer connection kit - combination low volts
For appropriate electrical connector for the dry pumping system, refer to:
▪ Figure: The Harting Han® K 4/4 cable-mounted connector
▪ Figure: The Harting Han® 100A axial screw module cable-mounted connector
▪ Figure: Customer connection kit - combination low volts GXS750
Use the following instructions to make the electrical supply cable:
1. Refer to
appropriate cable for the dry pumping system.
Note:
The kit of parts for the dry pumping systems with the Harting Han® 100 A and
Han® 200 A axial screw modules may contain a choice of inserts suitable for
different wire sizes as detailed in
correct insert for the size of the wire that is to be used is selected.
2. Screw the cable gland onto the hood.
