2.4 Safety equipment
WARNING
Danger due to malfunctioning safety equipment
For safe operation, be sure all features are in good working
order.
Therefore:
• Always check functionality of safety equipment according to the
maintenance plan.
• Never disengage safety equipment.
• Safety equipment may never be bypassed or modified.
Integration of an emergency-stop system required (for
certain applications).
The device is only intended for installation into an applica-
tion or system. It does not have its own operating control el-
ements and does not have its own
emergency-stop-function.
Install the device so that it is part of an emergency shut-off
system and can be stopped if necessary.
The emergency shut-off system has to be connected in such
a way that a disruption of the power supply or the reactiva-
tion of the power supply after a power disruption cannot
cause a hazardous situation for persons and objects.
The emergency shut-off system must always be easily ac-
cessible.
NOTE
The processor must decide which applications require the
installation of an emergency shut-off system.
2.5 Modifications to the
device
To avoid hazardous situations and to ensure optimal perfor-
mance, do not make any changes or modifications to the de-
vice unless they have been specifically authorized by
Ewellix.
