Electrical connection
6. Lay the connection cable in such a way that it touches neither the pipes nor the
pump.
7. Use a heat-resistant connection cable if fluid temperatures exceed 90 °C.
NOTICE
If flexible cables are used for the mains connection or communication connection,
use wire end ferrules!
Unoccupied threaded cable glands must remain closed with the plugs provided by
the manufacturer.
NOTICE
In regular operation, it's better to switch the pump on or off instead of switching the
mains voltage. This is done via the digital input EXT. OFF.
Line terminal connection
The middle terminal connection is sealed.
Protective ground conductor connection
When using a flexible connection cable, use a ring lug for the earth wire (Fig. 24).
When using a rigid connection cable, connect the earth wire in a U-shape (Fig. 25).
