Safety 2
(7) Electrical Safety
Work on the electrical system or equipment can only be carried out by a skilled and qualified
electrician or by specially instructed personnel under the control and supervision of such an
electrician. Work on the electrical system must be in accordance with applicable electrical
engineering rules and regulations.
Use only original fuses with the specified current rating. Switch off the machine immediately if
trouble occurs in the electrical system.
Machines with high-voltage electrical equipment must be suitably earth bonded by a qualified
electrician before activating the main isolator switch. If machine is electric-hydraulic or direct
electric drive, the ‘mains’ electrical supply to the machine must always be isolated by unplugging/
uncoupling the ‘mains’ power socket. It is recommended that an earth leakage safety switch is
fitted in the supply line to the power point on site. Special care must be taken to ensure that earth
wires are correctly connected.
When working with the machine, maintain a safe distance from overhead electric lines. If work is
carried out close to overhead lines, the working equipment must be kept away from them. Check
out the prescribed safety distances.
If your machine comes into contact with a live wire:
• Warn others against approaching and touching the machine.
• Have the live wire de-energized.
If provided for in the regulations, the power supply to machines and parts of machines, on which
inspection, maintenance, and repair work is carried out, must be isolated. Before starting any
work, check the de-energized parts for presence of power, and ground or short circuit them, in
addition to insulating adjacent live parts and elements.
The electrical equipment of the machine must be inspected and checked at regular intervals.
Defects such as loose connections or scorched or otherwise damaged cables must be rectified
immediately.
Necessary work on live parts and elements must be carried out only in the presence of a second
person, who can cut off the power supply in the case of danger by actuating the emergency shut
off or main power switch. Secure the working area with a red and white safety chain and a warning
sign. Use insulated tools only.
Before starting work on high-voltage assemblies and after cutting out the power supply, the
feeder cable must be grounded. Components such as capacitors must be short-circuited with a
grounding rod.
Tracked machines are wired with negative earth. Always observe correct polarity.
Always disconnect battery leads before carrying out any maintenance to the electrical system or
servicing the engine. Never short across the starter terminals of a battery as it can cause a fire
and could also damage the electrical system. Make sure that the powerpack is isolated if welding
is carried out on the machine.
The battery contains sulfuric acid, an electrolyte which can cause severe burns and produce
explosive gases. Wear personal protective equipment and avoid contact with the skin, eyes, or
clothing.
