4.1.5 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 0.75 mm² (single-core or multi-core as per
VDE 0100)
Cable insulation must meet the relevant temperature requirements and environmental
conditions.
Fuses (F1) used inside the LMV37.4 6.3 AT DIN EN 60127 2 / 5
4.1.6 Connections of actuators
The ready connected actuator cables must not be extended.
