into the tractor under overhead lines.
Behavior in the case of voltage flashover of overhead lines
High electric voltage may be applied to electrically conducting parts of the machine due to
voltage flashover. In case of voltage flashover, a voltage drop where major voltage differences
are present is created on the ground around the machine. Due to major voltage differences in
the ground, people may be killed by electric shocks when making big steps, laying on the
ground or supporting themselves with their hands.
Do not leave the cabin.
Do not touch any metal parts.
Do not establish any conductive connection to the ground.
Warn people: Do not approach the machine. Electrical voltage differences on the ground
may lead to severe electric shocks.
Wait for help from professional rescue teams. The overhead line must be switched off.
