M58800880_H - Installation
WARNING:
Risk of electric shock. Isolate the electrical supply before disconnecting the electrical
supply cable from the dry pumping system.
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:
A second protective earth (ground) conductor (with a cross-sectional area at least
2
equal to the phase conductor size up to 16 mm ) must be fitted to the protective
earth (ground) stud. Refer to Figure: The controls/connectors on the rear of the pump
(system with rear exhaust and castors/levelling feet fitted) item 15.
WARNING:
All connections to the interface control must be double insulated or have the
equivalent protection. Do not connect the 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.
WARNING:
The power wiring to the dry pumping system must be properly protected.
CAUTION:
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.
CAUTION:
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 the
properties directly connected to an electrical supply network which also supplies
domestic buildings.
CAUTION:
Do not connect voltages greater than specified in Table: Electrical connections to the
control/interface connections as it may cause damage to the interface control.
