UPS Remote shutdown option.
Shorting pins 5 and 6 on the DB9 connector will shutdown the UPS output in any mode of operation. Removing the
short circuit, the UPS will automatically auto-restart.
Where there is a requirement for a remote shutdown of the UPS to meet fire or other local safety codes, it is necessary to
interrupt, at the same time with the same pushbutton, all mains input supplies to the UPS. The pushbutton that provides
the UPS remote shutdown must be of the stay-down type ( Latching) to keep a short circuit on pins 5 and 6 until
mechanically unlatched by hand.
Note:
The wiring for remote stop contacts pins 5 and 6 of the DB9 connector are defined as SELV . When connecting to
a stop button interfacing with other mains emergency stop circuits, keep wiring segregated from other power wiring.
