DANGER
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 accidental-
ly switched on.
In case of unintended flow of water through a non-energized pump
there is a risk that the moving parts of the pump and the motor will
start rotating, thereby generating voltage over the terminals. The
size of the voltage depends on the speed of rotation. Due to this the
motor terminals must be considered as live until proven otherwise.
