DANGER
Danger to life due to spread of fire caused by use of housings that do not meet
the required standards!
Fire and smoke can cause severe personal injury or property damage.
● Install devices without a protective housing in a metal control cabinet (or
provide equivalent protection for the device) in such a way that contact with
fire is prevented.
● Ensure that smoke can only escape via controlled and monitored paths.
DANGER
Danger to life due to the motor catching fire in the event of insulation overload!
There is a greater load on the motor insulation through a ground fault in an IT
system. If the insulation fails, it is possible that death or severe injury can occur
as a result of smoke and fire.
● Use a monitoring device that signals an insulation fault.
● Correct the fault as quickly as possible so the motor insulation is not
overloaded.
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 (A5E34257946A AB).
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.
