1.1 General safety instructions
DANGER
Electric shock and danger to life due to other energy
sources
Touching live components can result in death or severe
injury.
•
Only work on electrical devices when you are qualified for
this job.
•
Always observe the country-specific safety rules.
Generally, the following six steps apply when establishing
safety:
1. Prepare for disconnection. Notify all those who will be
affected by the procedure.
2. Isolate the drive system from the power supply and take
measures to prevent it being switched back on again.
3. Wait until the discharge time specified on the warning
labels has elapsed.
4. Check that there is no voltage between any of the power
connections, and between any of the power connections
and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are
de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g.
compressed air, hydraulic systems, or water. Switch the
energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational
readiness in the inverse sequence.
WARNING
Electric shock due to connection to an unsuitable
power supply
When equipment is connected to an unsuitable power
supply, exposed components may carry a hazardous
voltage that might result in serious injury or death.
•
Only use power supplies that provide SELV (Safety Extra
Low Voltage) or PELV- (Protective Extra Low Voltage)
output voltages for all connections and terminals of the
electronics modules.
WARNING
Electric shock due to damaged motors or devices
Improper handling of motors or devices can damage them.
Hazardous voltages can be present at the enclosure or at
exposed components on damaged motors or devices.
•
Ensure compliance with the limit values specified in the
technical data during transport, storage and operation.
•
Do not use any damaged motors or devices.
WARNING
Electric shock due to unconnected cable shield
Hazardous touch voltages can occur through capacitive
cross-coupling due to unconnected cable shields.
•
As a minimum, connect cable shields and the conductors
of power cables that are not used (e.g. brake cores) at
one end at the grounded housing potential.
WARNING
Arcing when a plug connection is opened during
operation
Opening a plug connection when a system is operation can
result in arcing that may cause serious injury or death.
•
Only open plug connections when the equipment is in a
voltage-free state, unless it has been explicitly stated that
they can be opened in operation.
WARNING
Risk of electric shock and fire from supply networks
with an excessively high impedance
Excessively low short-circuit currents can lead to the
protective devices not tripping or tripping too late, and thus
causing electric shock or a fire.
•
In the case of a conductor-conductor or conductor-ground
short-circuit, ensure that the short-circuit current at the
point where the inverter is connected to the line supply at
least meets the minimum requirements for the response
of the protective device used.
•
You must use an additional residual-current device (RCD)
if a conductor-ground short circuit does not reach the
short-circuit current required for the protective device to
respond. The required short-circuit current can be too low,
especially for TT supply systems.
WARNING
Risk of electric shock and fire from supply networks
with an excessively low impedance
Excessively high short-circuit currents can lead to the
protective devices not being able to interrupt these short-
circuit currents and being destroyed, and thus causing
electric shock or a fire.
•
Ensure that the prospective short-circuit current at the line
terminal of the inverter does not exceed the breaking
capacity (SCCR or Icc) of the protective device used.
WARNING
Electric shock if there is no ground connection
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.
WARNING
Electric shock due to residual charges in power
components
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.
NOTICE
Property damage due to loose power connections
Insufficient tightening torques or vibration can result in loose
power connections. This can result in damage due to fire,
device defects or malfunctions.
•
Tighten all power connections to the prescribed torque.
•
Check all power connections at regular intervals,
particularly after equipment has been transported.
WARNING
Spread of fire from built-in devices
In the event of fire outbreak, the enclosures of built-in
devices cannot prevent the escape of fire and smoke. This
can result in serious personal injury or property damage.
•
Install built-in units in a suitable metal cabinet in such a
way that personnel are protected against fire and smoke,
or take other appropriate measures to protect personnel.
•
Ensure that smoke can only escape via controlled and
monitored paths.
WARNING
Active implant malfunctions due to electromagnetic
fields
Inverters generate electromagnetic fields (EMF) in
operation. People with active implants in the immediate
vicinity of this equipment are at particular risk.
