CAUTION: To ensure the UPS stops supplying power to the load during any mode of operation, the input
power must be disconnected from the UPS when the emergency power-off function is activated.
NOTE: For Europe, the emergency switch requirements are detailed in Harmonized document HD-384-48 S1,
“Electrical Installation of the Buildings, Part 4: Protection for Safety, Chapter 46: Isolation and Switching.”

NOTE: The pins must be open to keep the UPS running. If the UPS shuts down because the REPO connector
