Opening apparatus /
Electrical connection
The electrical connection of the apparatus
may only be carried out by specialized
personnel.
To open the plug and socket system
components, first remove the protective cap
and then proceed as follows:
6.2.1 Crimp connection
The insulation shall reach up to the plug
pins or contact sockets. The conductor
itself shall not be damaged.
To connect the correctly stripped connection
conductors of the cable proceed as follows,
whereby the relevant regulations shall be
taken into account (plug pins and contact
sockets are included loose with the plug,
coupler, flange socket and inlet).

Metal
5-pole (4+PE)
Connection in acc. Fig. 4, A-H (page 19-20)
1.
First, after undoing the locking screw,
Item 3, the pressure piece, Item 2, of the plug
is screwed out of the plug sleeve, Item 17,
and the insert parts, Items 4-7, 9, 13-14, are
pulled out backwards out of the plug sleeve.
2.
Push the stripped connection wires of
the connection cable (ca. 8 / 5mm) into the
connection opening of the plug pins, Item 13,
or into the PE connection lug, Item 9, and
crimp them on using the special crimping tool
(available under Order No. GHG 5901902
R0001).
Optionally, these pin connections can be
soldered on. The soldered joint shall be
protected additionally with a shrink-on
sleeve.
3.
After having crimped / soldered on
the connection cable, push the plug insert
parts, Items 4-7, and the pressure piece onto
the connection cable.
In order to get a perfect function of the
plug, you use also the not occupied pins.

Then push the connected plug pins
into the borehole of the plug insert, Item 14,
from the rear until reaching the stop (with
normal manual strength and in consideration
to hexagon guide) and push the insulating
sleeve, Item 7, over it up to the plug insert.
Now press the PE lug into the recess in the
plug insert and push it into the groove on the
front of the plug insert until it engages (see
also Figs. A-H).
Warning: Once the plug pins have been
pushed into the plug insert, the pins
cannot be dismantled again.
5.
Now the plug insert parts can be
pushed back again in the correct positions
into the plug sleeve, Item 17, from the rear,
the pressure piece, Item 2, can be screwed
on again until the seal and strain-relief
become effective (see Technical Data for test
torque) and locked with the locking screw,
Item 3.
