4.2.4 Supply voltages
The EtherCAT Box is supplied with two supply voltages. The supply voltages are electrically isolated in the
EtherCAT Box.
• Control voltage U
S
• Peripheral voltage U
P
Redirection of the supply voltages
The IN and OUT power connections are bridged in the module (not IP204x-Bxxx and IE204x). The supply
voltages U
S
and U
P
can thus easily be transferred from EtherCAT Box to EtherCAT Box.
NOTE
Pay attention to the maximum permissible current!
Pay attention also for the redirection of the supply voltages U
S
and U
P
, the maximum permissible current for
M8 connectors of 4 A must not be exceeded!
4.2.4.1 Connectors
NOTE
Risk of confusion: supply voltages and EtherCAT
Defect possible through incorrect insertion.
• Observe the color coding of the connectors:
