Pin Description
1 +24 V DC Us (Σ 2A max for all Us from GCC)
2 STO channel 1 (24v DC, 0.5A max)
3 0 V DC
4 STO channel 2 (24v DC, 0.5A max)
5 Feedback STO (non-safe)

The image below will provide an example of wiring STO output to drives with STO-input:

Auxiliary ports

On the front panel there are also two auxiliary ports marked with AUX. These ports are not connected and optional for the user to reconfigure.

Robot Connector

The Application Case 48V has one Robot Connector for the user to connect a robot to. And still make it possible to connect separately without connector. In the robot connector there are three connectors:

  • 48V DC power connectors
  • Robot EtherCAT Connector
  • Robot STO Connector

Switching the Case on

The 48V Application Case can be turned on by rotating the main disconnector. When set to “1” the Status LED should light up White, indicating that the Case is provided with 48V DC.

If this it not the case it might be possible that the circuit breaker is tripped. Resetting the Circuit breaker can be done by the following steps

  1. Remove the side cover by removing 4 Phillips screws as shown in the figure below

  1. When finished mount the right cover back on to the case. Make sure all that all panels line out correctly before fastening the Phillips screws.

Switching the Case off

The 48V Application Case can be Turned Off by rotating the main disconnector. When set to “0” the Status LED will fade out, indicating that the Case is no longer provided with 48V DC.
