Installation
CAUTION
All systems are supplied already configured for your electrical supply. You cannot reconfigure the system
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 properties directly connected to an electrical supply network which also supplies
domestic buildings.
CAUTION
Do not connect voltages greater than specified in
Table 9
to the control/interface connections. If you do, the
interface control may be damaged.
Contact Edwards if you wish to use the system with a power supply in a different voltage range to that specified on
the rating plate.
The system is protected from motor overloads and short circuits by solid state electronics. The power wiring between
the system and your electrical installation must be protected. When selecting overload protection, refer to
Section 2.5
. Pump rating information can be found on the label on the rear of the pump.
If you connect the electrical supply to your 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, and suitable for short duration
switch-on surges, and for high leakage current (for example, type B, according to EN50178).
The secondary protective earth (ground) is required in case of failure of the primary earth and because pump filters
can cause high earth leakage currents, refer to
Table 8
.
WARNING
Ensure that the system and your 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. You must fit a second protective earth (ground) conductor
(with a cross-sectional area at least equal to phase conductor size up to 16 mm
2
) to the protective
earth (ground) stud,
Figure 4
, item 16.
WARNING
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.
If you do, the interface control will not provide protection against electric shock.
WARNING
The power wiring to the system must be properly protected.
