3.2.2.3 Supply voltage output X60
The supply voltage output is intended for EtherCAT devices that are connected to EtherCAT junction X40
[
}
20] .
CAUTION
The outgoing peripheral voltage Up‘ is not switched off when the incoming peripheral volt-
age U
P
is switched off. (from hardware version 03)
Actuators at the supply voltage output remain active.
• To safely switch off actuators at the supply voltage output, use TwinSAFE components.
NOTE
The outgoing supply voltages are not electrically isolated.
(from hardware version 03)
The analog specifications of EtherCAT Box modules with analog inputs or outputs may not be met under
certain circumstances.

Up‘ is branched off from different supply voltages, depending on the hardware version:
• From hardware version 03:
Up‘ is branched off from the incoming control voltage U

• Up to and including hardware version 02:
Up‘ is branched off from the incoming peripheral voltage U
P
at X70 [ } 18] .

is connected to pin 3, GND
P
to pin 4. Starting with
hardware version 03, both pins are connected to the same ground potential GND
