(3) SDx output assignment can be customized for MicroLogic 5, 6, and 7 trip units, by using EcoStruxure Power Commission software.
NOTE: The indication (changeover) contacts are represented in the switchboard by the state of the Normally Open (NO) contact.

The state of the NO contact is open:

  • for OF contacts when the circuit breaker is in the O (OFF) position.

  • for SD, SDE, and SDV contacts when the associated function is not active.

Operation of the Wireless Indication Auxiliaries

The wireless indication auxiliary provides the same information as a standard wired auxiliary contact in OF, SD, or SDE positions. The information is sent remotely to a gateway or Panel Server.

During commissioning of the wireless indication auxiliary, the user defines the type of information sent: Open/Close or Trip.
