WARNING:
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.
WARNING:
The second protective earth (ground) conductor (with a cross-sectional area at least
equal to the phase conductor size up to 16 mm
earth (ground) stud. Refer to
WARNING:
The power wiring to the dry pumping system must be properly protected.
CAUTION:
To ensure compliance with European Electromagnetic Compatibility (EMC)
requirements for EMC emissions, note that it is not intended for use in domestic
buildings, or in the properties directly connected to an electrical supply network
which also supplies domestic buildings.
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

WARNING:
The mains terminal is not approved for connection and disconnection under load.
Use the following instructions to make the electrical supply cable:
