■ The output in watt is the recommended
connected load.
■ The total output of all connected appli-
ances must not exceed 1000 W. If the
total output
≤
1000 W, the individual
rating of a component can be greater
than specified.
■ The stated current indicates the max.
breaking capacity of the switching con-
tact (observe the total current of 5 A).
■ Controls for external heat source and
central fault message are unsuitable
for safety LV.
