COVER FIBER OPTIC CABLE - AR82.95-P-0005-01A
Do not remove protective covers too early from the fiber optic cable coupling (3) or the device connection
(4) because contaminated or scratched surfaces may absorb the light. Fiber optic cables must not be kinked,
routed over sharp edges or bent in radii of less than 25 mm, otherwise the fiber optic cable core will be
yellowed and broken. Yellowed or broken fiber optic cables weaken the light.
The work procedure is shown on components of the digital data bus (D2B).
1. Carefully detach the fiber optic cable coupling (3) from the device connection (4) and cover it with a
protective cap (1), stop plug (2) or a clean rag.
