BECKHOFF EP2xxx - Manual (Page 42)

Product overview
Note
The connected sensors are powered via Up, not from Us
The EtherCAT Box EP2339­0022 supplies digital sensors in contrast to many other mod­
ules from the auxiliary voltage Up, not from the Control voltage Us! This happens because
the connectors can be used alternatively as input or as output. Anyway an overload of the
sensor supply (current > 0,5 A) is here also displayed by red shining of the LED Us.
Attention
For switch off in the event of a fault, do no external sensor power supply
If the design of your installation is such that the power supply voltage Up is switched off in
the event of a fault, you must not power the connected sensors externally, but only through
the EP2339­0022! Otherwise, when the Up energy is switched off, the EP2339­0022 can
continue to draw energy from the external sensor power supply, and the outputs will not be
switched off!
