164201785—Rev 2 www.eaton.com/powerquality 29 Installing a Remote Emergency Power-off The REPO is used to shut down the MBM bypass from a distance. When the REPO is activated, the MBM opens the Bypass breaker and removes power from the critical load if the MBM is in Bypass mode. If the MBM is in Normal mode, the load will continue to be powered by the UPS. To remove power from the load, the REPO connected to the UPS must be activated. CAUTION l The REPO switch must have a minimum rating of 250 Vac at 20 mA and be a n ...
