Safety Notes

Risk of electrocution!
Danger to life or risk of serious injuries.
WARNING
• Disconnect the system and device from the power supply and ensure
they remain disconnected during electrical installation.
• The device may only be used for the applications described in the mu-
tually applicable operating instructions / data sheet. The notes in the
respective documentation must be heeded. The permissible ambient
conditions must be observed.
• The contact protection of the elements connected and the insulation of
the supply cables must be designed in accordance with the requirements
in the operating instructions / data sheet.
• Note the VDE and local regulations, particularly those related to protec-
tive measures.
Risk of explosion and fire or other thermal hazards!
Danger to life, risk of serious injuries or property damage.
WARNING
• The device may only be used for the applications described in the mu-
tually applicable operating instructions / data sheet. The notes in the
respective documentation must be heeded. The permissible ambient
conditions must be observed.
• The device may only be installed and put into operation by experts who
are familiar with this technical documentation and the applicable health
and safety and accident prevention regulations.
Functional error!
Danger to life, risk of serious injuries or property damage.
WARNING
• The device may only be used for the applications described in the mu-
tually applicable operating instructions / data sheet. The notes in the
respective documentation must be heeded. The permissible ambient
conditions must be observed.
• The device may only be installed and put into operation by experts who
are familiar with this technical documentation and the applicable health
and safety and accident prevention regulations.
Installation fault!
Danger to life, risk of serious injuries or property damage.
WARNING
• The relay must only be replaced by equivalent devices marked according
to the relevant safety rules.
• For the test and the maintenance of motor protection devices for explo-
sion proof machines, the EN 60079-17 and the safety rules that result
from the motor application and the corresponding type of protection have
to be respected (EU ATEX Directive 2014/34/EU and EN 60079-14).
• Details of the motor supplier and the details about the explosion protec-
tion from the EC-type examination certificates for explosion proof motors
have to be respected.
• If variants are used that have no no-voltage safe reset function additional
measures have to be applied in order to disable safely the restart of the
motor until the fault is removed if this leads to a dangerous situation.
• The motor protection relay has to switch off the motor immediately also
when it is controlled by an inverter. The control circuit must allow this. In
this case the sensor wires must be lead separately. The use of wires
inside the motor connection cable is not allowed.
!
Attention!
• Opening the device or implementing unauthorized changes voids any
warranty.
• Devices that show obvious transportation damage must not be used in
safety relevant applications.
