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!
