2.3 Residual hazards
WARNING
Missing safety equipment
Operation without safety installations is dangerous. The operator is responsible for the
realisation of a suitable safety concept. The operator must provide for sufficient safety
measures such as protective grating, light grids, emergency stop button, covers, warning
notices, etc. Operation without safety equipment is prohibited. Injuries caused by squee-
zing or pulling in.
Missing danger signs
Damaged or illegible danger signs no longer fulfil their purpose. Make sure the danger
signs are complete and legible. Replace damaged danger signs.
Danger of explosion
Danger of explosion during operation in a potentially explosive atmosphere. Operation in
a potentially explosive atmosphere is prohibited according to correct use. Only correct
use is permitted. Injuries caused by an explosion.
Incorrect spare pats / mounting of ancillary equipment
The use of incorrect spare parts or the mounting of unauthorised ancillary equipment can
lead to subsequent damage with the risk of injury. Only use spare parts from our spare
parts list or spare parts we have approved. The mounting of ancillary equipment must be
coordinated with us. Injury of persons due to subsequent damage.
Impermissible modifications
Impermissible modifications can lead to subsequent damage with risk of injury. Modifica-
tions on the machine are prohibited. Injury of persons due to subsequent damage.
Electric shock
Power and control connections may still conduct electricity after the machine has been
deactivated and is stationary. Energised capacitors inside the servo drive may still be
charged, despite the power supply being deactivated. Work on electrical equipment
should only be realised by skilled electrical personnel and under observance of specifica-
tions in the electrical operating manual. Electrical connections for the machine should
only be loosened or plugged in when the power supply is deactivated and secured against
reactivation. The status of capacitor charging should be measured prior to working on
machine electrical equipment. The procedure for measuring charges is described in the
electrical operating manual. Touching energised components can lead to serious or even
fatal injuries.
Squeezing or pulling in
The rotary disc of the machine turns at a very high speed. Extremities can be crushed or
pinched when interfering with the motion sequence. Never put hands into the work area
of the machine. Injuries caused by squeezing.
