WARNING
Line of supply current
Connect the unit at ground before carrying out any other operation.
The voltage input corresponds to the data written on the panel and on the pump.
( 400V ± 10% 50/60Hz x DUPLEX-UP-T )
( 230V ± 10% 50/60Hz x DUPLEX-UP-M ).
Make sure that the power-supply-cable can bear the nominal current and connect it to
the terminals of the general switch of the control panel.
If the cables are exposed, they must be appropriately protected.
The line must be protected with a differential magnetotermic switch measured in
accordance with the regulations locally in force.
Line of motor power supply
Connect the unit at ground before carrying out any other operation.
The voltage input corresponds to the data written on the motors.
(400V±10% 50/60Hz three-phase)
(230V±10% 50/60Hz single-phase).
Doing some starting make sure that the motors respect the right direction of rotation
usually indicated by an arrow printed on the motors.
Line of external control
It is possible to control the motor in “Automatic” using a free voltage contact
normally open as a float switch or a pressure switch.
It is a line in very low voltage and not a power line. Connect anyway with the control
panel switched off and with the circuit breaker disconnected.
