The overload protection of the Smartformer was tripped. Activate the overload protection using the
following procedure.

• Wait at least 10 minutes.
• Switch the overload protection to 0.
• Switch the overload protection to 1.
Possible cause of fault: Too many loads are connected via "Load L2".
• Switch off individual loads.
