WARNING!
The safety fuse used internally has a switching
capacity of 1500 A. If the short-circuit current in the
supply network may be greater than 1500 A, the
pump should be fused with an appropriate pre-fuse
with a higher switching capacity (rated current of
less than 1500 A).
Use an electrical isolating device in the mains
supply cable, such as a mains switch, to de-ener‐
gise the pump independently of the entire installa‐
tion (e.g. for repairs).

* internal - isolated, external - connect to a free terminal.
** twist the three individually concentric protective earth conductors
together, cover with yellow/green hose and connect to the protec‐
tive earth conductor terminal.
If the pump is connected to the mains in parallel with inductive con‐
sumers (e.g. solenoid valve, motor), it must be electrically discon‐
nected from these consumers in order to prevent damage due to
induced voltages when shutting down.
