12.1 Safety instructions for cable fault location
WARNING
Potential differences between the system and the earth possible
Danger to life or risk of injury due to electric shock.
If a cable fault is located near to the system, there may be potential
differences between the system and the earth in surge mode.
Place the system at a distance of several meters to the cable route
or cable fault location.
If operating in ‘surge mode’, cordon off the system at distance of at
least 1.5 m.
During surge mode, people may only stand outside the cordoned off
