Connectors UIC 558 – Installation and Maintenance Instructions
5. Installation
DANGER
The connectors contain components
that carry voltage. Risk of electric shock!
Always observe the following safety
regulations before beginning any work
on electrical constructions:
X
Disconnect
X
Ensure that it is not possible to re-
connect unintentionally
X
Clearly mark your work area
X
Make sure that there is no voltage
present
X
Earth and short circuit the instal-
lation
X
Insulate or cover adjacent ener-
gized parts
X
Only an electrically skilled person
may determine if there is no volt-
age present
NOTICE
During installation, ensure that dirt caused by sur-
rounding construction activities does not get into
the connectors.
5.1 Check Parts for Transport Damage
NOTICE
If parts are damaged, the functional reliability of the
connectors is no longer given.
X
Before installing, check all parts for any possible
transport damage.
X
Do not install any damaged parts.
5.2 Dimensions/Interfaces to the
Vehicle
The dimensions to the interfaces of the vehicle are given
in the respective data sheets or in our catalogue F120.en.

5.3 Installing Coupling Receptacles
Preliminaries
The assembly has to be carried out by qualified trained
personnel.
Correct mounting position
The break-away connector function guarantees a non-
destructive separation of plug and receptacle when
two electrically not uncoupled vehicles move away
from each other. For this purpose, the mounting posi-
tion of the coupling receptacle must be performed in
compliance with UIC 558 VE in order to guarantee the
prescribed tensile forces / directions on the flexible ca-
ble.
Fig. 4/D
shows an example:
Vertical mounting posi-
tion, lid opening to the top.
Moreover, a mounting position up to an angle of max.
90° clockwise is possible for coupling receptacles. In
this instance, the lid must show downward (for exam-
ples refer to
Fig. 4/E and F
).
NOTICE
An installation of the coupling receptacle with lid
showing upward (refer to
Fig. 4
/
G
) is not permissible!
When the lid is open in this mounting position, con-
tamination and moisture might penetrate the con-
tacts and accumulate there during the plugging
procedure or in the plugged condition. Moreover,
this mounting position causes a not definable limi-
tation of the prescribed tensile forces / directions on
the flexible cable and thus on the contact retainer
and locking mechanism. In this mounting position,
the plug connection is strained in transverse direc-
tion and the cable causes a unilateral strain on shell,
contacts and locking mechanism!

Requirements to the vehicle wall / mounting surface
The surface of the vehicle wall / mounting surface must
show an average surface roughness Rz of 6.3 ... 12.5 µm.
The tightening torque for the fastening screws is
10.5 Nm, for screws of steel with strength class 8.8.
