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 limit thermostat, 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
internal unit fuse (max. 6.3 AT).
Min. cross-sectional area
Cable insulation must be suited for the respective temperature and environmental
conditions!
