I/O devices
CAUTION
Fault caused by I/O devices
The connection of I/O devices can cause faults in the device.
The result may be personal injury and damage to the machine or plant.
•
Only connect I/O devices which are approved for industrial applications in accordance
with EN 61000-6-2 and IEC 61000-6-2.
•
I/O devices that are not hotplug-capable may only be connected after the device has
been disconnected from the power supply.
NOTICE
Damage through regenerative feedback
Regenerative feedback of voltage to ground by a connected or installed component can
damage the device.
Connected or built-in I/Os, for example, a USB drive, are not permitted to supply any voltage
to the device.
Regenerative feedback is generally not permitted.
Note
When measuring the counter emf, remember the following:
•
The IPC in question must be turned off and the power supply connector must be plugged
in.
•
During the measurement, all cables from the plant to the IPC should be connected.
•
All other components in the plant must be active.
