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
4.0 -
Installation Drawings
).
