NOTICE
Nationally applicable guidelines, standards and regulations as well as the
requirements of local energy supply companies must be observed!
NOTICE
Tightening torques for the terminal screws, see table "Tightening
torques". Only use a calibrated torque wrench!
1. Observe the current type and voltage on the rating plate.
2. Establish the electrical connection via a fixed connection cable equipped with a con-
nector device or an all-pole switch with a contact opening width of at least 3 mm.
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. 8, 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.
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
It is preferable to switch on or off the pump with the digital input (Ext.
Off) instead of the main power supply.
