  • Page 5: Installing Pump In The Well

    6.1 Installing pump in the well To reduce noise transmission it is advised to use plastic pipes. The pump must always be secured in the well through a special rope attached to loop on the pump head. It is recommended not to drop the pump in the well by using the electric cable, its integrity must be preserved in all operations.

  • Page 6: Pump Cable

    6.3 Pump cable NERA pumps are equipped, in their standard configuration, with 2,5 meter flat cable length. It is necessary to respect polarity ! Not respecting the polarity causes irreparable pump failure If the distance between the pump and the power supply is longer than the supplied cable it is necessary to make a junction performed by the special kit supplied as standard.

  • Page 7: Water Level Sensing

    To make the junction is necessary to follow carefully the instructions inside the kit. At the time of joining and electrical connection is essential to maintain the correspondence between the cables. After cable joining and placed the pump in the well you must perform, before connecting to power supply, a test of insulation: join together the two power cables and, applying a voltage of 500V, an insulation resistance from the ground higher than 100 Mohm must be verified.

    7. Troubleshooting If the pump, after the installation and power supply connection, doesn’ t provide any water please verify:  correct wiring.  voltage conditions (70 – 190 VDC).  enough power available (solar irradiance).  water presence: if pump during operation runs dry, an alarm occurs and pump will stop. Every 5 minutes pump will attempt to restart the operation after 5 minutes.
