NOTE

Check the optical fibers that have been assembled with ST connectors on one or both sides before you start
the installation.
An ST connector is required on the CC-CO connection side. Assemble the plug on the other side according
to the fiber-optic connection for the protection/terminal device (for example, ST connector, FSMA
connector).
Clamp the CC-CO onto a 35 mm × 7.5 mm DIN rail according to DIN EN 60715. Only horizontal wall
²
mounting is permitted (connections facing downwards).
Attach a solid low-impedance protective and working grounding to the connection side of the device
²
with an M4 screw. The cross-section of the line must be equal to the maximum cross-section of any other
control conductor connected to the device. It must thus be at least 2.5 mm
Line Interface
Connect the pair of wires to the Line connection of the CC-CO and the cable shielding to the shield using
²
a screwdriver with a M4 screw. The polarity of the connector is insignificant.
Connect the optical transmission line of the protection device to the optical reception connection of the
²
CC-CO and the reception interface of the protection device to the transmission connection of the CC-CO.
Attach the cables for the available auxiliary voltage to the CC-CO using a screwdriver. While doing so, pay
²
attention to correct polarity with direct voltage.
The Life Contact can be connected as a make contact or a break contact. Siemens recommends wiring as
²
a break contact if there is a fault (Life Contact 1 to 2), as this also enables line breaks and connection
contact errors to be detected.
