2.2. Electrical system maintenance
D Work on electrical equipment or components is only to be carried out by qualified
electricians or other professionals, or by assistants under their supervision and
control, observing electrotechnical regulations.
D Local electrotechnical and electric safety regulations must always be observed.
D Always use only original electrical components.
D If disturbances in the electricity supply occur, stop the vehicle at once.
D Voltage must be cut off from the parts of the equipment or devices that are to be
checked, serviced, or repaired, if regulations so require. Check that the
disconnected parts are dead, and then lock the main switch or arrange grounding
for the work if necessary.
D Do not touch battery terminals, alternator terminals, or wiring while the engine is
operating. Severe electrical shock, which may result in injury, could occur due to
improper shielding of electrical components.
D Check the electrical devices of the machinery regularly. Faults, such as loose wires
and damaged insulation, must be repaired at once.
D When handling high-voltage components, remember that capacitors may be
charged even if the voltage is cut off. Discharge the capacitors with a grounding
rod.
D Before making any c h a n ges concerning the electrical devices, SANDVIK
TAMROCK’s electrical en g ineering department must be consulted and a
written auth o rization received, to ensure t h at t h e op eration of th e d evice
does not change.
