Safety class
To DIN EN 60730-1:
∂
Safety class I
For applications without safe separation.
Protection against electric shock is achieved
through double or reinforced insulation.
Provision for the protective earth connection
is made in the plug-in base AGK11.7. When
replacing LAE10 / LFE10 with KF8896 and
LFS1, the maximum safety class that can be
∂
Safety class II
achieved is I.
For applications with safe separation.
Protection against electric shock is achieved
through double or reinforced insulation.
