Mounting The Optical Detector - ABB Arc Guard System TVOC-2 Installation And Maintenance Manual

Mounting the
Optical detector
This section is about optical detectors and the mounting is described using
examples:
• Where to positioning the detectors.
• How the detectors are mounted on busbars system.
This section also describes how to connect the detectors to the Arc Monitor.
Decide where to position the detectors on the basis of knowledge of your
own system. The main issue is to cover all components that might suffer from
an arc.
Warning!
Make sure that supply voltage is switched off!
