Input and forwarding
| |
Power supply from SELV/PELV power supply unit! SELV/PELV circuits (Safety Extra Low Voltage, Protective Extra Low Voltage) according to IEC 61010-2-201 must be used to supply this device. Notes:
|
| |
Observe the UL requirements
|
Notice | |
Brake chopper required Overvoltage peaks can occur on the supply voltage UP which can destroy the device. The overvoltage peaks occur during braking operations of the motor or by manually moving objects on the roller conveyor.
|
The EtherCAT Box is supplied with two supply voltages. The supply voltages are electrically isolated in the EtherCAT Box.
Redirection of the supply voltages
You can connect several EP7402 in series by forwarding the supply voltages and EtherCAT via X71 to the respective subsequent device.
Notice | |
Note the maximum current When forwarding the supply voltages US and UP, make sure that the current of 28 A at 45 °C permitted for the connectors is not exceeded: |
Pin assignment
Notice | |
UP is not protected against polarity reversal Defect possible through polarity reversal.
