6
Buttons (Front Panel)
Basic Operation
Use the
POWER
button to switch your UPS between its four modes of operation.
OFF:
No indicator lights are on. The UPS is completely shut down for storage or shipping. If the UPS is connected to AC
power, it will start up in
STANDB
Y mode. If the UPS is not connected to AC power and the
POWER
button is pressed for
two seconds, the UPS will “cold start” into
INVERT
mode.
STANDBY:
The “ ” light is flashing. The UPS is receiving AC power and using it to charge its batteries, but its outlets are
not active. Pressing the
POWER
button while the UPS is in
STANDBY
will put the UPS in the ON mode. Unplugging the
UPS or cutting AC power while the UPS is in
STANDBY
will put the UPS in the
OFF
mode.
ON:
The “ ” light is on. The UPS is receiving AC power, charging its batteries and delivering power to connected
equipment. If AC power is lost while the UPS is
ON
(i.e. a blackout occurs), the UPS will switch into
INVERT
mode.
Pressing the
POWER
button while the UPS is
ON
will put the UPS in
STANDBY
mode.
INVERT:
The “
” light is flashing. The UPS is powering connected equipment from battery backup. If AC power is
restored, the UPS will switch to the
ON
mode. Pressing the
POWER
button while the UPS is in
INVERT
will put the UPS
into the
OFF
mode. If the UPS is in
INVERT
and its batteries are drained, the UPS will switch to the
OFF
mode until AC
power is restored, then switch to the
ON
mode.
Use the
MUTE/TEST
button to do two things:
SILENCE ALARM:
Your UPS has three alarms. The first, the
INVERT
alarm, emits four short beeps every ten seconds when
the UPS is in
INVERT
mode, to warn you that AC power has failed. The second, the
OVERLOAD
alarm, emits short, rapid
beeps when the UPS is in
INVERT
mode if the total power draw of connected equipment exceeds the UPS’s output
capacity, to warn you to reduce the load. The third, the Low Battery alarm, emits a constant beep when the UPS is in
INVERT
mode and its batteries are very nearly depleted, to warn you that connected equipment must shut down. To silence
the
INVERT
or
OVERLOAD
alarms, press the
MUTE/TEST
button. The
LOW BATTERY
alarm will only stop when the UPS
switches to the
OFF
or
ON
mode.
SELF-TEST:
If your UPS is in the
ON
mode and has a load connected, you may test its batteries by pressing the
MUTE/
TEST
button for two seconds. The UPS will switch to
INVERT
mode for several seconds. Normally, the
INVERT
alarm (four
short beeps) will sound, indicating that the system is working properly. If the
OVERLOAD
alarm (short, rapid beeps) sounds,
reduce the load on the UPS. If the
LOW BATTERY
alarm (a constant beep) sounds, your UPS’s batteries may need
replacing, your external battery connection may be loose or the batteries may simply be less than fully charged. Check the
external battery connection, let the UPS charge for 12 hours, then perform a second self-test. If the
LOW BATTERY
alarm
sounds again, contact Tripp Lite for service. Do not unplug your UPS to test its batteries, or you will remove safe electrical
grounding and may introduce a damaging surge into your network connections.
Indicator Lights (Front Panel)
All Indicator Light descriptions apply when the UPS is plugged into a wall outlet and turned ON.
POWER:
Lights green when the UPS is receiving AC power. Illuminates constantly when the UPS is in the
ON
mode,
indicating that batteries are charging and connected equipment is receiving filtered AC power. Flashes while in
STANDBY
mode to indicate that batteries are charging but connected equipment is not receiving power.
VOLTAGE CORRECTION:
Lights green whenever your UPS is automatically correcting high or low AC line voltage. The UPS
will also click gently. These are normal, automatic operations of your UPS, and no action is required on your part.
BATTERY CHARGE:
This multicolored light displays 7 separate UPS battery charge conditions. It will turn from red (low) to
yellow (medium) to green (full) to show you the level of battery charge. If the light is constant, your UPS is in the
ON
or
STANDBY
mode, operating from line power, and the battery is charging. If the light is flashing, your UPS is in the
INVERT
mode, operating from battery, and the battery is discharging. If the light is flashing red, your UPS is in the
INVERT
mode
and is nearly out of power: you should save files and shut down your equipment immediately.
OUTPUT LOAD:
This multicolored light shows how heavy your UPS’s load is. Steady green indicates a light load, steady
yellow a medium load. When the light is red, your UPS is supporting a load above 85% of its capacity. If the red light begins
flashing, then your UPS is severely overloaded. Immediately remove load from the UPS until the light stops flashing.
