3.1 Connection of optical bus lines
Use a duplex fiber-optic cable with BFOC/2.5 (ST
connectors to connect the individual repeaters.
Pay attention to the maximum cable length of the
fiber-optic cable as well as the possible types of
fibers specified in the Technical Data.
Make sure that each optical input a is connected to
an optical output J at the opposite end ("cross-over
link").
The corresponding BFOC sockets of the two ports are
marked on the lower front panel.
Ensure sufficient strain relief for the fiber-optic cables
and pay attention to their minimum bending radii.
Unused BFOC sockets must be sealed with the sup-
plied protective caps. Incident ambient light and, in
particular, excessively high ambient brightness can
affect the network.
The penetration of dust may impair operation of the
optical components.
3.2 Mounting the repeater
The FIP repeater OZD FIP G3 ... can either be mounted
on a 35 mm DIN rail as per IEC 60715:1981 + A1:1995 or
directly on a flat surface.
The selected installation location must comply with
the climatic limits specified in the Technical Data.
Make sure there is sufficient space for connection of
the bus and power supply lines.
To facilitate installation of the fiber-optic cables,
they are to be connected before the repeaters are
mounted.
If possible, the repeaters should only be installed on
a mounting plate or DIN rail with low-impedance and
low-inductance grounding. If the mounted DIN rail
and mounting plate are insulated, the repeater must
