WARNING
Danger to life due to fire if overheating occurs because of insufficient
ventilation clearances!
Insufficient ventilation clearances can result in overheating with danger to persons
as a result of smoke and fire. This can also result in increased downtime and
reduced service lives for devices and systems.
● Ensure compliance with the specified minimum clearances as ventilation
clearances for the relevant components. These are specified in the Operating
Instructions for the Control Unit (A5E34257946B).
WARNING
Risk of explosion as a result of ignition of a potentially explosive
atmosphere!
The device is not approved for operation in areas with potentially explosive
atmospheres. If it comes into contact with a potentially explosive atmosphere, the
device could ignite the atmosphere and cause an explosion.
● Never install or operate the device in environments in which potentially
explosive atmospheres can develop.
3.5.4 Dangers due to electromagnetic fields
WARNING
Danger to life due to electromagnetic fields!
Variable speed drives generate electromagnetic fields (EMF) in operation. People
with pacemakers or implants are at particular risk in the immediate vicinity of
these devices/systems.
● If you have a heart pacemaker or implant, maintain a minimum distance of 2
m.
● Display an appropriate warning symbol in the area around the variable speed
drive.
3.5.5 Dangers due to parameterization errors
DANGER
Danger to life due to machine malfunctions caused by incorrect or changed
parameter settings!
Machines can malfunction as a result of incorrect or changed parameter
assignment, which in turn can lead to injuries or death.
● Protect the parameterization (parameter settings) against unauthorized
access.
● Respond to possible malfunctions by applying suitable measures (e.g.
EMERGENCY STOP or EMERGENCY OFF).
