Section 300: Operation
This section will describe how FERRUPS works. We’ll discuss the meaning of the front panel lights and describe
how to use the control panel. We’ll also describe what the automatic system test does, what each alarm means,
what parameters are, and how to read the Alarm and Inverter Logs. Finally, we’ll see how to turn off FERRUPS.
301 Front Panel Lights
At the front of your FERRUPS is a panel with five lights (LEDs). These lights tell you several things about the
operating status of the FERRUPS.

AC LINE Green FERRUPS is getting power
from the AC input power
source. (Models FE 1.8, FE
2.1, and FE 3.1 with Serial
Numbers 25000 and up must
be turned on in addition to
being connected to AC power
supply. FERRUPS is not getting
input power; there is an
outage, the AC input breaker
is tripped, the UPS is
unplugged, or, for later
models FE 1.8, FE 2.1, and
FE 3.1, the On/Off switch is
not on. Not applicable.
READY Green FERRUPS is ready to provide
backup power from its
batteries when needed. FERRUPS cannot provide
backup power; it may be in
the Line Condition Mode or
the Off Mode (see
Section
302 ), or its batteries may be
discharged, or it may be
running on battery power
(Inverter On mode).
You have just started the
UPS; the UPS is testing the
batteries as part of the
automatic system test (see
Section 303); or, you have
started a timed shutdown
(
Section 402).
CHARGING Green FERRUPS is charging the
batteries. The battery charger is off;
batteries are at full charge. Not applicable.
BATTERY
POWER Yellow FERRUPS is providing power
from its batteries; it is in the
Inverter Mode. FERRUPS is providing
condi-tioned power from the
AC input power source, or
FERRUPS is off. The UPS is testing the
inverter as part of the
automatic system test. (See
Section 303 .)
ALARM Red FERRUPS is warning you that
an alarm exists. If you have
not silenced the alarm beeper,
you should be hearing a code
that tells you what the problem
is. (See
Section 304 .) If you
have a control panel, an alarm
message appears on its
display.
No alarm exists. Not applicable.
