above are alarm and operation set points, calibration factors and other settings. You usually do not need access to these parameters for normal operation of the UPS. If you need information about the full range of UPS parameters, call your service representative to ask for TIP 407 or TIP 503. TIP 407 describes communication from a control panel. TIP 503 describes communication through the RS-232 port.

UPS Shutdown

The FERRUPS UPS is designed for many years of round-the-clock operation. Usually, you do not need to shut down the UPS, even if your equipment is shut down for several days. Even when it’s not powering your equipment, the UPS monitors its internal condition and keeps the Time and Date parameters current.

There are times, though, when you want to shut down the UPS, such as:

hd When you do not expect to use it for an extended period of time.

id When it is being serviced. ld Before you move it.

nd When it has gone into the Off mode because the batteries have been discharged during an extended outage.

od When a system malfunction requires a UPS shutdown.
