6.3 Cable entries (KLE); blanking plugs

6.3.1 Plug and socket

Flexible cables shall be used with trum
petshaped cable glands or other suitable
entries with additional pullrelief.

When using cable entries with a lower IP
protection than that which applies to the device
(see page 7, technical data), the IP protection of
the whole device will be reduced.

The mounting directives applicable to the cable
entries used shall be observed.

Unused holes shall be closed with a blanking
plug in order to establish the minimum
protection category.

In case of sealing inserts that are cut out, it
shall be ensured that the insert is properly
adapted to the cable diameter. Care has to be
taken that when fitting the cable entries,
sealing inserts appropriate to the cable
diameter are used.

In order to ensure the required minimum
protection category, the cable glands are to
be tightened down.

Overtightening might impair the protection
category.

All vacant metric CCH / CEAG cable entries
shall be closed with the certified blanking plug
for metric cable entries.

6.3.2 Plug

Fig. 9: In general, only the sealing inserts fitted
in the plug may be used. When mounting the
cable, attention has to be paid that sealing
inserts matching the cable diameter be used.
After having connected the cable, the coupling
ring item 2 is to be screwed fingertight until the
sealing effect is obtained. Then the screws item
4, of the pull-relief item 3, are to be tightened
down.

Mind! Overtightening might impair the
pullrelief effect!

6.4 Closing the device

In order to ensure the required minimum
protection category, the cover screws, the
screws of the plug and the coupler shall be
tightened down.

Overtightening might impair the protection
category.

Any foreign matter shall be removed from
the device.
