1.4.3 General Safety Notes
DANGER!
Life-threatening hazard from electric shock!
There is an imminent life-threatening hazard from
electric shocks from live parts. Damage to insula‐
tion or to specific components can pose a life-
threatening hazard.
– Only a qualified electrician should perform
work on the electrical equipment.
– Immediately switch off the power supply and
have it repaired if there is damage to the insu‐
lation.
– Before beginning work at live parts of electrical
systems and resources, cut the electricity and
ensure it remains off for the duration of the
work. Comply with the five safety rules in the
process:
– cut electricity;
– safeguard against restart;
– ensure electricity is not flowing;
– earth and short-circuit; and
– cover or shield neighboring live parts.
– Never bypass a fuse or render it inoperable.
Always use the correct amperage when
changing a fuse.
– Keep moisture away from live parts. Moisture
can cause short circuits.
WARNING!
Hazards due to insufficient prime mover protection
The engine, turbine, or other type of prime mover
should be equipped with an overspeed (over-tem‐
perature, or over-pressure, where applicable) shut‐
down device(s), that operates totally independently
of the prime mover control device(s) to protect
against runaway or damage to the engine, turbine,
or other type of prime mover with possible personal
injury or loss of life should the mechanical-
hydraulic governor(s) or electric control(s), the
actuator(s), fuel control(s), the driving mecha‐
nism(s), the linkage(s), or the controlled device(s)
fail.
