Powerware FE/QFE UPS manual

m

To restart the UPS, break the connection between Pins 6 and 21 (or between Pins 18 and 21) at the UPS’s RS-232 port. Then, follow the steps in “Startup” on page 17 for your model. Note that the 12V level on Pin 6 or Pin 18 is only available when the UPS is operating.

You can change the type of signal that the UPS responds to and how quickly it responds. You can also set up the UPS to restart automatically when the shutdown signal stops. See TIP 503 or contact your service representative for more information.
