Completing Installation
²
Resume operation of the device.
NOTE
In order to warrant safe functioning, the affected sensor must be substituted after detection of an arc.
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.
Line Sensor
Description
The line sensor detects arcs in the control cabinets of the air-insulated system part.
