2.4.1 Hazards due to electricity
DANGER
Warning of electrical hazard
Direct contact with live parts or with parts that became energized due to
faults poses an immediate threat to life. Damage to the insulation or to
individual components may be life-threatening. Short-circuits and over-
loading pose the risk of being hit by ejected molten parts.
–
Always ensure that the electrical supply units remain locked. Only au-
thorized persons with a key or special tool are permitted to access the
units.
–
Work on the electrical actuator equipment may only be carried out by a
qualified electrician.
–
Always operate the actuator with the hood in place.
–
When working on live components or lines, a second person must al-
ways be present to interrupt the power supply in case of an emergency.
–
Regularly inspect the electrical equipment of the actuator for defects
such as loose connections or damaged insulation.
–
Immediately disconnect the power supply in case of defects, and have
the device repaired.
–
Always switch off the power supply to the electrical actuator equipment
and verify its voltage-free condition before carrying out any work on it.
–
Switch the power supply off before carrying out service and repair work,
and protect it from being switched on again.
–
Do not bypass any fuses and do not put fuses out of operation.
–
Ensure the correct tripping current when replacing fuses.
–
Protect live parts from humidity as it may cause short circuits. Never
clean the electrical equipment with water or similar liquids.
–
Have electrical machinery and stationary electrical equipment checked
by a qualified electrician at least every 4 years (also refer to the section
“7.2.1 Maintenance intervals” ).
–
Modifications made after the inspection must comply with the applicable
standard.
