1.
First, after undoing the locking screw,
Item 3, screw the pressure piece, Item 2, of
the coupler out of the plug sleeve, Item 1, and
pull the insert parts, Items 4-6, + 20, out of
the coupler sleeve, Item 1, backwards.
2.
Thread the ends of the wires of the
connection cable, that have been stripped for
env. 8 mm (see also page 16), through the
pressure piece, Item 2, the strain relief, Item
4, the seal, Item 5, and the thrust washer
(screen clamp), Item 6.
3.
Insert a suitable tool (e.g. screwdriver
2.5x75) in the spring terminal release, Item
22, and then push the connection wires into
the open spring terminal, Item 23 (see Detail

When the tool (screwdriver) is
removed, pressure is applied to the spring
and the connection wire, thus establishing the
electrical contact between the connection
wire and the plug pin.
