Load
In order to guarantee sufficient terminal voltage, a maximum load resistance R
L
(including
line resistance) must not be exceeded depending on the supply voltage U
B
of the supply
unit.

Supply voltage
• Error current is output and "S803" displayed (output: MIN alarm current)
• Periodic checking to establish if it is possible to quit fault state

Post-connection check
Is the device or cable undamaged (visual check)?
Do the cables comply with the requirements ?
Do the cables have adequate strain relief?
Are all the cable glands installed, firmly tightened and leak-tight?
Does the supply voltage match the specifications on the nameplate?
Is the terminal assignment correct ?
If required: Has protective ground connection been established ?
1)
The SIO mode supports 250 mA, thus deviating from the IO-Link standard.
