NOTE:
Excessive tightening compromises
the protection class.
The following is to be considered
when assembling the sealing plug:
1 . Only the sealing plug belonging to
the cable gland (
5
) may be used.
2. The head side of the sealing plug
must be on the outside (
5
).
3. The sealing plug (
5
) is to be
pushed into the cable gland as
far as it will go.
Assembly and installation
Loosen the cover screws
(
2
)
and
remove the cover
(
1
)
(see device
overview). Insert the lower part into
the opening
(
3
)
using four 4 mm
screws with a head diameter of 6
mm to 7 mm and fasten to the wall
or ceiling or onto a plate. If the head
diameter of the screws is too small,
suitable washers of 6 mm to 7 mm in
diameter are to be used in addition.
Lead the connection lines through the
screwed cable connectors (KLE)
(
4
)
and connect them to terminals in
accordance with connection diagram.
For the pre-installed cable glands,
only lines are to be used which
have a sheathing diameter Ø of 5.5
mm to 1 3 mm, since otherwise the
IP66 housing protection class is not
ensured.
The tightening torque of these
screwed cable connectors is 3.5 Nm.
The tightening torque of the cover
screws is 1 .2 Nm.
