3.3.3 Earthing
3.3.4 General recommendations
To prevent serious or fatal electric shock, proceed as follows:
• Connect the control box, all metal pipes, and the motor frame to the
power supply earth terminal using a copper wire.
• Comply with local electrical regulations. The earth conductor must at
least be the same size as the power supply wires.
• Permanently insulate all unused wire ends in the control box and other
equipment.
3.3.5 Protection
DANGER
Electric shock
Death or serious personal injury
- Switch off the power supply on the mains switch, not in the
control box, before working on or around control box, pipes,
cables, pump or motor.
- Install an earth conductor of at least the same size as the
submersible drop cable. Run the earth conductor as short a
distance as possible and fasten it securely to a true earth
connection, such as the submersible motor.
- Wear rubber gloves and boots and take care to connect metal
control boxes and motors to the power supply earth connection
or a steel pipe or casing extending into the well.
When installing the motor and the control box, include circuit and
component protection.
Only use the pump for pumping fresh groundwater. Do not use the
pump in swimming pools or marine areas.
