Control Cable and Communication
Based on your site’s specific needs, the UPS may require auxiliary connections to manage the
battery system (external battery circuit breaker), communicate with a personal computer or
provide alarm signaling to external devices, or for Remote Emergency Power Off (REPO). The
External Interface Board, arranged for this purpose, is next to the option box in the Rectifier
section (refer to
). The contacts are rated for 250VAC @ 2A.
