Information about laying fiber-optic cable
To ensure the smooth transfer of data via the fiber-optic cable, you must en-
sure that mechanical loads are avoided when laying the fiber-optic cable and
later on during operation. Also observe the information from the manufactur-
er of the fiber-optic cable and the following instructions:
▪
Radii must not fall below the minimum permissible bend radii (do not
bend fiber-optic cable).
▪ The fiber-optic cables must not be over-stretched or crushed. Observe
the permissible load values.
▪ The fiber-optic cables must not be twisted.
▪ Be aware of sharp edges which could damage the fiber-optic cable's
coating when laying or could place mechanical loading on the coating
later on.
▪ Provide a sufficient cable reserve near distributor cabinets for example.
Lay the reserve such that the fiber-optic cable is neither bent nor twisted
when tightened.
Mounting terminating resistor of CAN bus
If you want to operate the device in parallel operation, you need to mount a
120 Ω terminating resistor at both ends of the CAN bus. Use the plug con-
nector with terminating resistor provided as an option.

Connecting cables to the system periphery
To obtain a better overview when connecting cables, only use as many
leads as necessary.
