●
Pump must be earthed in compliance with regulations.
●
For pumps that are installed for stationary use, the metal pump housing must also be
earthed in accordance with EN 50014. Attach the protective conductor connection (as com-
pliant with EN 60335) to the drill hole labelled with the earth symbol (
) and located on the
handle using a suitable screw, nut, tooth lock washer and standard washer.
●
Use a cable with diameter of min. 2.5 mm² to 6 mm², or follow the local regulations, to con-
nect the protective conductor connection.
●
We also advise you to use a residual current operating device.
●
The switch box for the pump(s) should be obtained as an accessory.
ATTENTION!
Where you provide your own switch box, you must ensure it meets with
the following energy supplier requirements:
●
P2
≤
3.8 kW: direct starting
●
P2
≥
3.9 kW: star delta starting
●
The provisions laid down by your local energy supplier will determine the threshold between
direct and star delta starting.
●
Motor safety switch (set to the nominal pump motor current indicated on the rating plate).
●
A standard measuring appliance can be used to switch the thermal winding contact (WSK)
for the thermal monitoring of the motor. Switch at 230 V AC, max. 2 A.
Recommended level: 24 V DC.
