. Connection
See unit sticker / circuit diagram
After connecting correctly, attach the terminal cover
and tighten the
sealing screw
. After setting and programming the switching times,
attach the transparent cover on the upper edge of the housing, tilt it
downwards and secure with the sealing screw
. Both housing
sections can be fitted, sealed and opened independently of each other.
The accumulator
(plug-in unit) can be replaced if necessary.
Only accumulators of the corresponding type can be exchanged.
See sticker on the unit.
! Exchange the accumulator with care !
Hold it securely at the top and bottom ends and pull it out.
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
.
