See unit sticker / circuit diagram
After connecting correctly, attach the terminal cover

. Both housing sections
can be fitted, sealed and opened independently of each other.

Note
Electrical appliances may only be installed and assembled by a skilled
electrician. The term “skilled electrician” is defined in VDE 0105.
Grässlin time switches are largely protected against external interference.
However, if interference still occurs, measures to counter voltage peaks
can be taken with common components (varistors, suppressor diodes).
Particular attention must be paid to this when inductive loads are being
switched
.
If necessary, break off
the securing bracket and
push in on the upper
edge of the housing
