Electric shock
Death or serious personal injury
‐
Make sure that motor cable ends are not live before
starting work on the product.
‐
Make sure that the power supply cannot be
accidentally switched on.
In case of unintended water flow through a non-energized pump,
there is a risk that the moving parts of the pump and the motor may
start rotating, and generate voltage over the terminals. The size of
the voltage depends on the rotation speed. Therefore, the motor
terminals must be considered as live until proven otherwise.
