Underground electric lines

Overhead electric lines

2-16
• Observe the operating voltage of the machine/attachments. The voltages must be
compatible (12 volts) and confirm that an appropriate fuse or circuit breaker is incorpo-
rated in the system to prevent damage from malfunction or short circuit.
• Always remove the grounding strap from the battery when working on the electrical
system or when performing welding work.
• Starting the machine with a battery jumper cable can be risky if performed improperly.
Observe the safety instructions regarding the battery.
• Before starting any work, the machine operator must ensure that there are no lines in
the work area.
• If you are not sure, contact the person in charge at the network operator.
• If there are lines, take the following safety measures:
• Mark the position and path of the lines unambiguously.
• Fasten, support or secure exposed lines.
• Safely fasten lines if vibration or shocks to these lines must be avoided.
DANGER
WARNUNG
Personal injury hazard due to electrical shocks!
Will cause severe injuries or death.
• During machine operation, maintain a safe distance from overhead electric
lines.
• If work must be performed close to overhead lines, the equipment/attachments
must be kept well away from them.
Rated voltage (volt)
Up to 1000 V
Over 1 kV to 110 kV

Over 220 kV to 380 kV
Unknown rated voltage
• If no sufficient distance can be kept to overhead electric lines, the machine operator
must take other safety measures, for instance switching off the current, in agreement
with the owner or operator of the lines.
• If an energized line is touched nevertheless:
• Do not leave the machine.
• Drive the machine out of the area.
• Warn others against approaching and touching the machine.
• Have the live wire de-energized.
