Mounting Instructions
2019-05-23 38-133905e
Description
The contact consists of two parts:
The vehicle section - contact box
Trailer section - socket
The socket and contact box have conduit entries
dimensioned for cables Ø10.5 mm - Ø17.5 mm. The
VBG Kontakt 14, 17 and 22 are designed such that the
socket automatically disconnects if you happen to forget
about it when uncoupling the trailer.
Identify all parts before assembly. All assembly and
service work must be performed carefully and in a
professional manner.
Follow the instructions. Always observe the vehicle
manufacturer’s instructions for electrical installation on
the vehicle.
Leave all instructions and directions in the vehicle for
the customer for reference in future service and
maintenance.
General
• Cable dimension shall always be chosen taking
power consumption into consideration. When
dimensioning, keep in mind any extra equipment that
may be fitted at a later date.
• Connect the 14/17/22-terminal socket only to the
corresponding 14/17/22-terminal contact box. Risk for
short circuits.

• Weekly maintenance of the contact surfaces involves
cleaning and corrosion resistance using VBG Electro
Oil.
• To be absolutely assured that the connection between
the contact box and the socket is correct, an optional
lock hook is available, part number 28-027600.
• In particularly severe operating conditions, the contact
box should be equipped with a heating coil, part number
28-029900.

Fitting the contact box
1. Fit an appropriate bracket on the vehicle. Locate the
control box horizontally and so that nothing prevents
the socket from disconnecting automatically.
2. Slip the conduit entries onto the cable - sealed nut
- washer - gasket.
3. If both conduit entries are not to be used, fit a plug
with washer and gasket.
4. Lock the cover in the open position.
5. Remove the insert and pull each cable through its
respective entry point. Pull it out as much as necessary
to work comfortably with the connections.
6. Strip the cable casing back about 60 mm.
7. Check and label the wires by function.
8. Strip the wires about 5 mm. Fit cable shoes with the
recommended dimensions.
9. Connect the cables to the flat connector blades in
the insert as per the wiring plan. Spray with VBG
Electro Oil onto the cable shoes and connector blades
to prevent corrosion.
10. Place the insert in the box and affix it using two
screws.
N.B. The upper edge of the insert shall be located inside
the support heel in the upper edge of the box (10b).
Close the cover.
11. Adjust the cable at each conduit entry point without
exerting pressure on the cable.
12. Insert and tighten the conduit entry with moderate
force so that it seals.
13. Tighten the contact box in the brackets with three
screws, lock washers and nuts. The contact box shall
be seated horizontally and with the label upwards.
This is important so that the socket can disconnect
automatically.
• Fit the electrical heating coil (where applicable)
between the parking light and earth in the contact box.
• Terminals 1 and 12 require larger cable shoes (9.5
mm). The cable dimension shall always be chosen
taking power consumption into consideration. When
dimensioning, keep in mind any extra equipment that
may be fitted at a later date.
