3. To protect against leakage and for strain relief to the threaded cable gland, use a con-
nection cable with sufficient outer diameter.
4. Guide the connection cable through the M25 threaded cable gland (Fig. 19, 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 digital input EXT. OFF.

Protective ground conductor connection
When using a flexible connection cable, use a ring lug for the earth wire (Fig. 22).
When using a rigid connection cable, connect the earth wire in a U-shape (Fig. 23).
Residual-current device (RCD)
This pump is equipped with a frequency converter. Therefore, it must not be protected by
a residual-current device. Frequency converters can impair the function of residual-cur-
rent-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 protection in the case of direct or indirect contact, only an RCD
or RCM of type B is permissible on the power supply side of this product.
