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
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. Electromagnetic fields may
interfere with active implants, e.g. pacemakers. People with active implants in the
immediate vicinity of an inverter are at risk.
•
As the operator of an EMF-emitting installation, assess the individual risks of persons
with active implants.
•
Observe the data on EMF emission provided in the product documentation.
