Equipotential bonding
Provide all components in the cooling system (motor, heat exchanger, piping system, pump,
pressure equalization tank, etc.) with equipotential bonding. Implement the equipotential
bonding using a copper rail or finely stranded copper cable with the appropriate conductor
cross-sections.
Note
Installation of the cooling water pipes
Electrically conductive cooling water pipes must not come into contact with live components.
• Ensure adequate insulation.
• Securely fasten the pipe.
