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 digital 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 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.
• Labelling:
• Trigger current:> 30 mA
Fuse on mains side: max. 25 A
The mains-side fuse protection must always correspond to the electrical configuration of the
pump.
Circuit breaker
The use of a circuit breaker is recommended.
NOTICE
Circuit breaker trigger characteristic: B
Overload: 1.13 – 1.45 x I
Short-circuit: 3 – 5 x I
