Tools and Materials
Note:
To avoid a possible galling of the housing cover with the housing base, it is
recommended before the final mounting to treat the housing cover thread with a mounting
paste for high-grade steel connections .
Before mounting and dismounting works the control has to be seperated from the mains!
Seperated plug and socket devices always have to be disconnected from the mains!
