2.2.2 Specific dangers
The following section lists the residual risks that have been
determined by the risk assessment.
• Heed the safety instructions listed here, and the warnings
in subsequent chapters of this Manual, to reduce health
hazards and to avoid dangerous situations.
DANGER
Danger to life caused by electric current!
Touching conductive parts causes a direct danger to life. Damage
to insulation or individual components can cause danger to life.
Therefore:
• In the event of damage to insulation, switch off the power supply
immediately and have the parts repaired.
• Work on the electrical system must be carried out only by profes-
sional electricians.
• De-energize the machine for all work on the electrical system.
• Before maintenance, cleaning or repair work, switch off the power
supply and perform lockout procedures so it cannot be turned on
again.
• Do not bridge fuses or make them ineffective. When changing
fuses, make sure you use the correct amperage.
• Keep moisture away from conductive parts. If you don’t, this can
cause short circuit.
WARNING
Danger of injury caused by moving components!
Rotating and/or linearly moving components can cause severe injury.
Therefore:
• Do not work on or place any of your body, hands, or arms near
moving components.
2.3 Safety equipment
WARNING
Danger due to malfunctioning safety equipment!
For safe operation, be sure all safety equipment is in good working
order.
Therefore:
• Always check functionality of safety equipment according to the
maintenance plan.
• Never disengage safety equipment.
• Safety equipment may never be by-passed or modified.
Integration in an emergency-stop system
required (for certain applications)
The actuator is only intended for installation into an an appli-
cation or system. It does not have its own operating control
elements and does not have an independent
emergency-stop-function.
Install the actuator so that it is part of an emergency shut-off
system and can be stopped if necessary.
The emergency shut-off system has to be connected in such
a way that a disruption of the power supply or the reactiva-
tion of the power supply after a power disruption cannot
cause a hazardous situation for persons and objects.
The emergency shut-off systems must always be freely ac-
cessible.
NOTE
The processor decides which applications require the
installation of an emergency shut-off system.
