Cable entries (KLE)/
Blanking plugs
Generally, only certified cable entries and
blanking plugs may be used. Flexible
cables are to be used with trumpet-
shaped cable glands or other suitable
entries with additional pull-relief.
The mounting directives applicable to the
fitted cable entries are to be observed.
When using cable entries with a lower IP
protection than that which applies to the
device (see technical data, page 9 + 10),
the IP protection of the whole device will
be reduced.
In order to establish the minimum protection
category, unused holes have to be closed
with a certified blanking plug.
Care has to be taken that when fitting the
cable entries, sealing inserts appropriate to
the cable diameter are used.
In case of sealing inserts that are cut out, it
will have to be ensured that the insert is
properly adapted to the cable diameter.
All vacant metric CEAG / CCH cable entries
are to be closed with the certified blanking
plug for metric cable entries.
In order to ensure the required minimum
protection category, the cable glands shall be
tightened down.

Overtightening might impair the
protection category.
Attention: When tightening the cap nut of
the type ADE 1F metal cable entry, the
screwing is to be protected against
twisting by means of a suitable tool.
6.4
Flange and metal plates
If flange plates have to be removed in case of
plastic terminal boxes (e.g. for drilling entry
holes), attention will have to be paid to the
proper fit of the flange plate and of the clamp
clip when mounting them in order to maintain
the minimum protection category.
Flange plates for stainless steel terminal
boxes shall be fitted so that the IP protection
in maintained. Pay attention to the proper
seat of the sealing element.
PE conductors fed from outside are to be
connected to the PE terminal provided on
the flange. The maximum cross-section is
50mm².
Attention: Metal flanges, metal plates and
metal cable glands shall be included in
the equip potential earth connection.

Closing the device/
cover closure
Any foreign matter is to be removed from
the apparatus.
In order to ensure the required minimum
protection category, the cover screws are to
be tightened down.
Overtightening might impair the
protection category.
6.6
Taking into operation
Prior to taking the apparatus into operation,
the tests specified in the relevant national
regulations will have to be carried out. Apart
from that, the correct functioning and
installation of the apparatus in accordance
with these operating instructions and other
applicable regulations will have to be
checked.
Incorrect installation and use of the
terminal boxes can invalidate the
guarantee.
