Use the POWERbutton 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 STANDBY
mode. If the UPS is not connected to AC power and the POWERbutton 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 internal batteries,but its outlets are not active. Pressing the
POWER button while the UPS is in STANDBYwill 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 OFFmode.
ON: The “ ” light is on. The UPS is receiving AC power,charging its bat-
teries 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 POWERbutton while the UPS is ON will put the UPS in
STANDBYmode.
INVERT:The “ ” light is flashing. The UPS is powering connected equip-
ment 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 INVERTwill 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 ONmode.
Use the MUTE/TESTbutton 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 INVERTmode, to warn
you that AC power has failed. The second,the OVERLOADalarm, emits short,
rapid beeps when the UPS is in INVERTmode if the total power draw of con-
nected 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 INVERTor OVERLOAD
alarms,press the MUTE/TEST button. The LOW BATTERY alarm will only
stop when the UPS switches to the OFFor ON mode.
Self-Test Batteries and Alarms: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 OVERLOADalarm (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 or they may simply be
less than fully charged. Let the UPS charge for 12 hours,then perform a second
self-test. If the LOW BATTERYalarm 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.
