ELECTRICITY HAZARDS
DANGER!
Risk of fatal injury from arc faults and electrical
current!
There is a direct risk of fatal injury from electric
shock in case of contact with live parts. Damage to
the insulation or individual components may
represent a risk of fatal injury.
Arc faults cause high pressures and temperatures.
Heated gases or metal parts can cause burns. Flash
burns to the eyes may occur due to light from an arc.
– Have work on the electrical components
performed by qualified electricians only.
– Only allow trained installation staff to carry out
installation and assembly work. Staff must be
sufficiently informed about possible hazards
which may arise in the installation and
assembly area.
– Wear electric arc safety clothing when working
in the vicinity of electrical systems.
– In case of damage to the insulation,
immediately switch off the power supply and
make repairs.
– When performing installation and assembly
work on or in the vicinity of bus bars,
implement measures in the working position so
it is and remains isolated from the voltage.
Follow the
five safety rules
:
1.
Isolate from the voltage.
2.
Secure to prevent from being
switched back on.
3.
Make sure parts are no longer live
with voltage.
4.
Earth and short-circuit
5.
Cover or section off neighboring
parts which are live with voltage.
– Make sure that the system is perfectly earthed
with a protective earth conductor system.
– Keep moisture away from parts which are live
with voltage, as this can cause a short circuit.
– Refrain from making any changes to the bus
bar system.
Recommendation:
After installation, perform a high voltage test in order
to check that the system has been properly installed.
Annually check the bus bar system and earthing for
mechanical damage, and use a thermal camera to
check for the generation of heat.
