Siemens SIPROTEC 5 Hardware Description

Mounting the Line Sensor
²
Fasten both busbar-coupler pieces in both the holes in the control-cabinet wall.
The busbar-coupler pieces (incl. nut and lock washer) are included in the scope of delivery for the sensor.
²
Connect one end of the line sensor to a busbar-coupler piece and route the sensor fiber along the section
to be protected, for example, the busbar.
²
Make sure that the piece of fiber exposed to the arc has a minimum size of 0.5 m and that the distance
from the potential arc source is a maximum of 0.25 m.
If these boundary conditions cannot be satisfied, please contact our Customer Support for further ques-
tions.
²
Fasten the sensor fiber, for example, with cable fasteners.
Ensure that the fiber is not damaged or broken when fastening.
²
The sensor fiber is non-conductive. However, ensure that the sensor fiber is laid in such way as to avoid
contact with hot or energized parts.
²
During installation, make sure that the sensor and the line are not damaged by sharp edges.
²
Sensor areas that should not react to light can be covered up.
²
Pass the sensor fiber back again and fasten it with the 2nd busbar-coupler piece.
²
The line must not be bent or stressed in any other way.
R = 50 mm (minimum bending radius)
Maximum continuous tensile force = 1 N
²
Fasten the supply line with the busbar-coupler piece to the side of the protection device.
²
Remove the dust caps from the plug and connect the supply line to the plug-in module.

NOTE
Order the line sensor and the supply line with a suitable line length. If the line is too long, it must not be
shortened! It must be rolled up with a minimum diameter of 0.3 m because of the optical loss.
Obey the general recommendations of the manufacturers of optical lines.
i
i
NOTE
The contact surfaces of the plug must be clean.
Completing Installation
²
Resume operation of the device.
i
i
NOTE
In order to warrant safe functioning, the affected sensor must be substituted after detection of an arc.

i
NOTE
Hereby, Siemens declares that until now, UL has neither investigated whether the device can detect an arc-
protection fault, neither if in case of an arc-protection fault, the safety of personnel and system is guaran-
teed.
