3.6 Electrical supply
All dry pumping systems are supplied already configured for an electrical supply. The dry pumping system cannot
be reconfigured between the low voltage (200 V to 230 V) and high voltage (380 V to 460 V) ranges.
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 Table 9 to the control/interface connections as it may cause
damage to the interface control.
Ensure that the electrical installation of the dry pumping system conforms with all local and
national safety requirements. It must be connected to a suitably fused and protected electrical
supply and a suitable Earth (ground) point.
This equipment is suitable for Installation Category II as defined in IEC 60664-1. The dry pumping
system must be connected to an isolator that disconnects all current carrying conductors and can
be locked out in the off position (LOTO). The isolator must be in close proximity to the equipment,
within easy reach of the operator and identified as the disconnect device for the equipment.
Isolate the electrical supply before disconnecting the electrical supply cable from the dry pumping
system.
Ensure that the dry pumping system and the electrical supply cable are suitably protected against
Earth (ground) faults and that the Earth (ground) conductor of the electrical supply cable is longer
than the phase conductors in the connector. A second protective Earth (ground) conductor (with
a cross-sectional area at least equal to phase conductor size up to 16 mm
2
) must be fitted to the
protective Earth (ground) stud, Figure 3 item 15.
All connections to the interface control must be double insulated or have equivalent protection.
Do not connect voltages greater than 30 V a.c. or 60 V d.c. to the control/interface connections as
the interface control will not provide protection against electric shock.
The power wiring to the dry pumping system must be properly protected.
