Total current for supply cable 1 on port X0i (i.e. port X01, X02, ... , X04);
corresponds to the current I
X0i_pin3_1L
on pin 3 (ground). This current is the
sum of the currents on pins 1, 2 and 4 of port X0i:

For supply cable 2 of the 0765-4203/0100-0000 IO-Link Module, the currents declared in
the following table must be taken into account:

Description
I
X31_2L
Current to connection PWR IN (X31): current 2L+ / reverse current 2L−
I

For this module, supply cable 2 is only used for transmission between the PWR IN (X31)
and PWR OUT (X32) connections.
During operation of the 0765-4203/0100-0000 IO-Link Module, the rules below for the
currents in supply cables 1 and 2 must be followed at all times:

6.2.2 Requirements on the Power Supply
Power Source
Note
PELV or SELV power source required
Only device the product with 24 VDC PELV (Protective Extra Low Voltage) or SELV
(Safety Extra Low Voltage) voltage sources. Failure to do so may result in electric shock.
If L1 and L2 are to be supplied separately (e.g., for safe switch-off of L2), then either cen-
tral grounding must be implemented using two power supply units, or the power supply
connection must be made on the same phase. However, the use of two separate power
supply units is not mandatory.
