Excessive current load
ATTENTION!
Equipment damage due to excessive current load!
An excessive current load may result in damage to the
equipment.
• Do not exceed the maximum permissible total current
of 8 A for the IO-Link Master.
• Each output provides a maximum current of 2 A.
• The sensors/bus and the actuator should be powered
via separate current sources if possible.
Incorrect grounding
ATTENTION!
Incorrect grounding!
An incorrect grounding may result in equipment damage
or malfunction.
• The grounding between the IO-Link Master and the
machine must be a low-impedance system.
• The ground connection must be as short as possible.
