Remote Contact

The remote contact interface is a standard feature and is available as dry switch contacts
through a DB9 male connector located under the Remote Eye Cover on the front of the UPS
(see Section 4 for 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, 0.1 A (125 VAC, 3 A).
3) Pin 3 is not used.
