Danger to life due to electric shock when not grounded
For missing or incorrectly implemented protective conductor connection for devices with protection class I, high
voltages can be present at open, exposed parts, which when touched, can result in death or severe injury.
•
Ground the device in compliance with the applicable regulations.
Danger to life due to electric shock when opening plug connections in operation
When opening plug connections in operation, arcs can result in severe injury or death.
• Only open plug connections when the equipment is in a no-voltage state, unless it has been explicit
ly stated
that they can be opened in operation.
Danger to life through electric shock due to the residual charge of the power component capacitors
Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the power supply has been
switched off. Contact with live parts can result in death or serious injury.
•
Wait for 5 minutes before you check that the unit really is in a no-voltage condition and start work.
Material damage due to loose power connections
Insufficient tightening torques or vibrations can result in loose electrical connections. This can result in damage due to fire,
device defects or malfunctions.
• Tighten all power connections with the specified tightening torques, e.g. line supply connection, motor connection, DC
link connections.
•
Check all power connections at regular intervals. This applies in particular after transport.
Danger to life due to fire spreading if housing is inadequate
Fire and smoke development can cause severe personal injury or material damage.
• Install devices without a protective housing in a metal control cabinet (or protect the device by another equivalent
measure) in such a way that contact with fire is prevented.
•
Ensure that smoke can only escape via controlled and monitored paths.
Danger to life from electromagnetic fields
Electromagnetic fields (EMF) are generated by the operation of electrical power equipment, such as transformers,
converters, or motors.
People with pacemakers or implants are at particular risk in the immediate vicinity of this equipment.
•
If you have a heart pacemaker or implant, maintain a minimum distance of 2 m from electrical power equipment.
Danger to life from permanent-magnet fields
Even when switched off, electric motors with permanent magnets represent a potential risk for persons with heart
pacemakers or implants if they are close to converters/motors.
• If you have a heart pacemaker or implant, maintain a minimum distance of 2 m.
• When transporting or storing permanent-magnet motors always use the original packing materials with the warning
labels attached.
• Clearly mark the storage locations with the appropriate warning labels.
•
IATA regulations must be observed when transported by air.
