Electrical Connection: ( 8.1 - 8.2 - 8.3) - ARVEN KONTRACT180 1 Mode D'emploi

WARNING! The pump should not be run dry! It should be put fully into the liquid to be pumped.
Slurping for long periods should be avoided.
The length of the power cable on the electropump limits the maximum depth of immersion at
which the pump may be used.
8 ELECTRICAL CONNECTIONS
CAUTION! ALWAYS FOLLOW THE SAFETY REGULATIONS!
8.1 The electrical installation must be carried out by an authorized and competent electri
cian who assumes all the responsibilities.
8.2.Ensure that the mains voltage is the same as shown on the plate of the motor to be fed and
be sure TO MAKE A GOOD GROUND CONNECTION.
8.3. The electropump, both the single-phase and the three-phase version is supplied with an
electric cable. If the power cable is damaged in any way it must be replaced, not repaired.
• It is advisable to connect the pump to a dedicated power line.
• IInstall a differential magnetothermal circuit breaker switch upstream from the pump, which is
reserved exclusively for pump power supply, with residual current of (IΔN) ≤30mA.
Install a device for the omnipolar disconnection from the mains network (switch to disconnect
the pump from the power supply).
• Switch off the power upstream from the system before making the electrical connection.
• Single-phase motors are provided with built-in thermal overload protection and may be
connected directly to the mains.
Warning: If the motor is overloaded it stops automatically. Once it has cooled down it
starts again automatically without requiring any manual intervention.
•Three-phase pumps must be protected with motor protectors suitably calibrated
according to the values on the data plate of the pump to be installed.
•Connect the pump cable to the electric panel, ensuring that the following parts
correspond:

• Before making a test start, check the water level inside the well.
