In most applications, the XPSUAK can be used as a replacement for the XPSAK with only minor wiring modifications. However, some applications may require additional changes to the control or safety circuit design to ensure correct operation with the newer safety relay.

Before implementing a replacement, review the comparison documents and verify that the proposed solution meets the functional and safety requirements of the application.
