WARNING
Danger of electrocution by contact during maintenance or overhaul
There is an electric shock hazard in case of contact with a product powered on and not electrically
isolated.
►
Before carrying out any work, set the main switch to O.
►
Disconnect the power cable from the mains.
►
Secure the installation correctly by tagging and locking (LO/TO) the system to prevent uninten-
tional re-engagement.
WARNING
Risk of electric shock in case of contact with the mains connector at power-off
Certain components use capacitors that are charged up to over 60 VDC and that hold their electrical
charge at power-off: residual voltages due to filter capacitance can cause electric shock, up to and
including mains voltage levels.
►
Wait 5 minutes after power-off before commencing work on the product.
NOTICE
Risk of electromagnetic disturbance
Voltages and currents can induce a multitude of electromagnetic fields and interference signals. In-
stallations that do not comply with the EMC regulations can interfere with other equipment and the
environment in general.
►
Use shielded cables and connections for the interfaces in interference-prone environments.
Electromagnetic compatibility
The product complies with industrial environment immunity and emission standards.
This product is designed for professional use with a power greater than 1 kW.
In the case of use in a laboratory environment, contact us.
Electrical safety
The pump motor is protected against overload by the current limitation of the electronic drive unit con-
troller (in case of overload, the speed decreases automatically).
When there is a hazard due to accidental contact with liquids, gases or solids, you must install a hard-
wired emergency stop circuit to cut the power supply.
►
Never override these interlocks during installation, use, or maintenance.
5.4.1 Customer electrical installation protection
Circuit breaker protection
The power circuit used to supply the pump must be fitted with a breaker complying with the IEC
60947-2 curve D standard whose short circuit cut-off capacity is at least 10 kA. This protection device
should be in close proximity to the pump (no further than 7 m away) and in line of sight of the product.
The customer must provide a correctly-rated main circuit breaker: see chapter “Electrical characteris-
tics”.
Differential circuit breaker
In the event of an insulation defect, you must install a differential circuit breaker to protect personnel
(see chapter “Electrical characteristics”).
The pump is Class 1 equipment and therefore must be grounded. The user must make sure the installa-
tion has an earth wire properly connected to the ground.
Grounding
When necessary, the installer must provide dual protection in addition to the existing one. It consists of
an uninsulated braid or a separate green/yellow conductor with a minimum section 3 mm
2
(9AWG). The
impedance between the pump body and the ground connection point must be < 0.1 Ohm at 25 A.
►
Use an M4 x 8 screw and a locking washer fitted to the hole from the pump to secure the conduc-
tor to the pump and to the installation’s ground connection point.
