Porsche 996 TT, Repair Manual

Page: 432 / 2099

Maximum permissible tensile load: 60 N •
Minimum bending radius after and during installation in vehicle: 25 mm •
Maximum number of torsions: 10 torsions per m •
The following points must be observed when installing optical waveguides and wiring harnesses containing
optical waveguides:
Damaged optical waveguides must not be installed. •
Before installing the optical waveguide or the wiring harness with optical waveguide into the vehicle,
you must check whether the protective dust caps have been attached properly. If this is not the case,
the optical waveguide set must not be installed. •
After and during installation of the optical waveguide into the vehicle, the minimum bending radius of
25 mm must be maintained. •
During installation of the optical waveguide into the vehicle, the optical guide must not be pulled to
set the length of the wiring harness (max. tensile load 60 N) and the optical guide must not be twisted
or coiled up. •
After installation of the optical waveguide into the vehicle, twisted optical guides must be
straightened. •
Lateral forces on the optical waveguides must always be avoided during installation of the optical
waveguide into the vehicle. •
Repairs
Defective optical guides must be replaced. Repairs for optical waveguides are not planned.
When replacing optical waveguides, the optical contacts must be removed form the plug connectors.

Plug connectors
Protective dust caps
Protective dust cap for optical contacts:
If an optical waveguide is stored, transported or installed in a vehicle, the protective dust cap most
only be removed immediately before use in the plug.
•
The protective dust cap must be replaced after every test of an optical waveguide. •
The protective dust caps can be removed without actuating a lock.
During or after removal of the protective dust cap, do not touch the exposed contact surfaces, because
otherwise the optical contacts may be damaged or soiled. •
Protective dust cap for plug (wiring harness side):
If a ready−made wiring harness is installed, protective dust caps are already present on the plug for the optical
waveguide.
