Edwards GXS Series User Manual

To use the dry pumping system with a power supply in a dierent voltage range to that
specied on the rang 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 installaon must be protected. When selecng input fuses, refer to Electrical
data on page 20. Pump rang informaon 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 protecon of equipment with a d.c.
component in the fault current, for short duraon switch‑on surges and high leakage
current (for example, type B, according to EN50178).
The secondary protecve earth (ground) is required in case of a failure of the primary
earth and because pump lters can cause high earth leakage currents. Refer to Table:
General electrical data.
3.6.1 Mains supply cable connecon
WARNING:
The Harng connector is not approved for connecon and disconnecon under load.
Three dierent types of electrical supply connector are used on the dry pumping
systems. A kit of parts containing the correct mang half connector is supplied with each
dry pumping system. Refer to Electrical data on page 20 for the details of the connector
types and the dry pumping systems to which they are ed. Informaon for wiring each
of these dierent connectors is given in:
▪ Figure: The Harng Han® K 4/4 cable-mounted connector
▪
Figure: The Harng Han® 100A axial screw module cable-mounted connector
▪
Figure: Customer connecon kit - combinaon low volts GXS750.
For appropriate electrical connector for the dry pumping system, refer to:
▪ Figure: The Harng Han® K 4/4 cable-mounted connector
▪ Figure: The Harng Han® 100A axial screw module cable-mounted connector
▪
Figure: Customer connecon kit - combinaon low volts GXS750
Use the following instrucons to make the electrical supply cable:
1.
Refer to Electrical data on page 20 for cable sizes and type to determine the most
appropriate cable for the dry pumping system.
Note:
The kit of parts for the dry pumping systems with the Harng Han® 100 A and
Han® 200 A axial screw modules may contain a choice of inserts suitable for
dierent wire sizes as detailed in Table: Electrical connecons. Ensure that the
correct insert for the size of the wire that is to be used is selected.
2.
Screw the cable gland onto the hood.
