Electrical connection
3. To protect against leakage and for strain relief to the threaded cable gland, use a
connection cable with sufficient outer diameter.
4. Guide the connection cable through the M25 threaded cable gland (Fig. 18, Item 1).
Threaded cable gland with the specified torques.
5. The cables near the screwed connection are to be bent to form a drain loop, to
drain any accumulated drips.
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 DI input EXT. Off.
Protective ground conductor connection
Use a ring lug when using a flexible connection cable for the earthing wire (Fig. 21).
When using a rigid connection cable, connect the earthing wire in a U shape (Fig. 22).
Residual-current device (RCD)
This pump is equipped with a frequency converter. Therefore, it must not be protec-
ted by a residual-current device. Frequency converters can impair the function of re-
sidual-current-operated protection circuits.
NOTICE
This product can cause direct current in the protective earthing conductor. When a
residual-current device (RCD) or a residual-current monitor (RCM) is used for pro-
tection in the case of direct or indirect contact, only an RCD or RCM of type B is per-
missible on the power supply side of this product.
