The pins labeled "NC" must not be contacted.
Before installation and commissioning, please also read the chapters Installation of EJ modules and Commissioning!

Reset function

To be able to use the optional reset function, the Reset SW1 and Reset SW2 pins of the module need to be connected to a push button of choice. By shortly pressing this button, both pins will be connected. Hereby the ground signal (connected to Reset SW1), will be detected by the reset input of the module, (connected to Reset SW2). As a result of this, the power module will restart.

Using the EJ940x power supply plug-in modules for E-bus refresh

The power requirement of the module strand is displayed in the TwinCAT System Manager.

Notice

Damaging, uncontrolled behavior or collapsing possible

When the maximum output current of the EtherCAT Coupler (e.g. EJ1100) is insufficient, the EJ940x power supply plug-in module can be placed in the same circuit.
To avoid negative influence, like damaging, uncontrolled behavior and collapsing, caused by using different power supply plug-in modules

power sources must be separated from each other (see following illustrations).
