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 "Tightening torques"
[} 145] 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 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.
