4.6 Cross-sectional areas

The cross-sectional areas of the mains power lines (L, N, and PE) and, if required, the
safety loop (safety temperature limiter, water shortage, etc.) must be sized for rated
currents according to the selected external primary fuse. The cross-sectional areas of
the other cables must be sized in accordance with the primary fuse for the LME7 (max.
6.3 AT).
Caution!
Risk of damage to the switching contacts!
If the external primary fuse (Si) is blown due to overload or short-circuit at the
terminals, the LME7 must be replaced.
Min. cross-sectional area
Cable insulation must be suited for the respective temperature and environmental
conditions!
