Mounting the Optical detector

WARNING
Make sure that supply voltage is switched off!

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. Min 100mm
Decide where to position the detectors on the basis of 1SFC170011M0201
knowledge of your own system. The main issue is to cover Figure 4

all components that might suffer from an arc.

INFORMATION
Excess plastic fiber cable should be wound up
and kept as a ring with a diameter of at least
100 mm (4 inches). The plastic fiber cables are
not to be bent in a loop with a radius of less
than 20 mm (1 inch) occasionally and 35 mm
(1.4 inches) for a long period of time.
