NOTICE
Nationally applicable guidelines, standards and regulations as well as the require-
ments of local energy supply companies must be observed!
NOTICE
Tightening torques for the terminal screws, see "Tightening torques" table. 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
connector 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
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.
