Remote Contacts

The remote interface is a standard feature and is available as solid state relay switch
Contacts through a DB9 male connector located on the back side of the UPS (see pages 45-
46 for DB9 connector location). The following chart shows the solid-state relay pin
assignment's for each signal and the associated DB9 connector pinout.
