Installation
For the mounting and operation, the
respective national regulations (e. g. ElexV,
equipment safety law for Germany) as well as
the general rules of engineering will have to be
observed.
The improper installation and operation of
safety switches may result in the
invalidation of the guarantee
6.1
Mounting
The wall sockets can be mounted without
opening their enclosure.
In case the wall sockets are mounted directly
onto the wall, they may rest evenly only at the
respective fastening points. The chosen screw
shall match the fastening hole (see dimensio-
nal drawing) and it must not damage the hole
(e. g. use of a washer).
The device shall be fastened diagonally with
at least 2 screws.
The wall sockets and flange sockets shall be
mounted so that the plug hole does not point
upwards.
If the screws are overtightened, the apparatus
may be damaged.
In the open air, the plugs must be kept with
the plug opening (pin side) pointing down-
wards or be closed with protective plug caps
available as an optional extra (see general
catalogue).
Before opening the apparatus, ensure that
it has been isolated from the voltage
supply, or take appropriate protective
meassures.
The insulation of the conductors shall
reach up to the terminal. The conductor
itself shall not be damaged.
The connectible min. and max. conductor
cross-sections shall be observed (see
technical data).
Taking into account the respective regulations,
the properly bared conductors of the cables
shall be connected.
The electrical connection of the plugs is
established as shown in fig. 4 and 5:
The plug insert (item 2, fig. 5) is removed from
the pin bushing (item 1, fig. 5), after the
fastening screws (item 3, fig. 4) have been
unscrewed. Thereafter, the plug insert can be
connected to the connections of the plug pins
(see view 1, fig. 5).
Attention: When the fastening screws (item
3, fig. 4) get lost, they will have to be
replaced by similar screws or to be ordered
directly from the manufacturer.
Type: Size 5 = KTG 50 x 50 x 50 / 25
Assembly is made in inverse order, after the
cable has been connected.
The inlets are electrically connected as
shown in fig. 6 through 8.
Fig. 6:
After unscrewing the two screws item 3, the
plug insert item 2 is removed from the flange
item 2.
Fig. 7:
Now the connecting leads item 4 can be
connected to the terminal L1... and PE als of
the plug insert item 2 as described in point
6.2.
Fig. 8:
Finally, using the self-cutting screws item 3,
the plug insert item 2 is screwed into the
flange, observing its proper position.
All screws and/or nuts of the supply
terminals, also of those remaining vacant,
shall be tightened down.
Excessive tightening may affect or damage
the connection.
The supply terminals are designed for the
connection of copper conductors. If multi- or
fine-wire connecting cables are used, the wire
ends will have to be handled in acc. with the
applicable national and international rules (e.g.
use of sleeves for strands).
