Residual hazards
Strong magnetic fields
Strong magnetic fields are emitted from the permanent magnets of the secondary part.
Assembly, commissioning and maintenance only by qualified, trained and instructed
personnel.
Pacemakers and/or medical The functioning of metal implants can be compromised.
Persons with pacemakers and/or medical implants made of metal may not handle the
machine under any circumstances. Danger of severe to fatal injuries.
Objects made of magnetisable materials such as jewellery, watches or tools can be
attracted. Do not wear any magnetisable materials when handling the machine. Handle
tools carefully. Injuries caused by being pulled in.
Missing safety equipment
Operation without safety equipment is dangerous. The realisation of a suitable The
operator is responsible for the 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
squeezing, impact, magnetism.
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 amplifier 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 secondary part of the machine moves 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.
