Remote Contact

The remote contact interface is a standard feature and is available as dry switch
contacts through a DB9 male connector located on the back side of the UPS (see
Section 9 for DB9 connector location). The following schematic shows the contact
state and pin assignment for each signal and the associated DB9 connector pin-
out.
Notes:
1) Switches are shown in their inactive states (if battery voltage is low pin 7 will be connected to System
Common).
2) Contacts are resistive loads rated at 30 VDC, 0.1A (125VAC 3A).
3) Pin 3 is not used.
