The Eaton Ferrups FX 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.
The following situations may require a UPS shutdown:
• When you do not expect to use it for an extended period of time.
• When it is being serviced.
• Before you move it.
• When it has gone into the Off mode because the batteries have been discharged during an extended
outage.
• When a system malfunction requires a UPS shutdown.
When AC input voltage is present, the UPS system can provide output voltage even though its batteries are
disconnected. To confirm that there is no UPS output voltage, always disconnect the AC input source; if the
UPS has one or more separate external battery cabinets, open the DC disconnect switch on each external
battery cabinet or disconnect the external battery cabinet from the UPS.

UPSs with a BPE type Break-Before-Make (BBM) bypass switch ( see the label inside the switch): shut
down the protected equipment. Turn the bypass switch to the LINE position. Continue to Step 2.

direct AC line instead of conditioned power from the UPS.
UPS with a BPE type Make-Before-Break (MBB) bypass switch (see the label on the side of the
switch): Verify that the AC LINE indicator is on, the BATTERY POWER indicator is off, and the UPS is
providing output. If all three of these conditions are present, turn the bypass switch to the LINE position.
Your equipment receives direct AC line instead of conditioned power from the UPS. Continue to Step 2.
If all three of these conditions are not present, follow steps 2–4 before you turn the bypass switch to the
LINE position. This causes a break in power to your equipment between shutting down the UPS and
turning the bypass switch to the LINE position.
Equipment can be damaged if you change the switch position when line is applied and the UPS is off or on
battery!
