If your power is out for an extended time, your FERRUPS will continue to provide power for your equipment
until it gets near the end of its runtime. If you wish, you can check how much runtime you have left by reading
parameter 9. (See 

.) At a set number of minutes before the end of the runtime (factory default setting

is five minutes), FERRUPS will sound a “Low Runtime” alarm (– 

 ). You should do an orderly shutdown of

your equipment when you hear this alarm. Then, turn your FERRUPS off (see 

) to conserve the

remaining battery power. When AC input power returns, turn FERRUPS on again so the batteries will recharge.

If your FERRUPS shuts itself down because its battery voltage is too low, shut FERRUPS off (see 

until AC input power returns.

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

There will be some times, though, when you want to shut down FERRUPS, such as:

1. When you will not be using it for an extended time;
2. When it is being serviced;
3. Before you move it;
4. When it has gone into the Off Mode because the batteries have been discharged during an extended

outage; or

5. When a system malfunction requires that you shut FERRUPS down.

1. Units with No Bypass Switch:

Turn off the protected equipment and connect it to standard wall outlets (receptacles). Restart the
equipment if you must use it while the FERRUPS is off. Go to step 2.
