OPERATION
nce the system has been properly installed, it is
ready to operate. The following procedures will
explain how to start-up the system while
plugged into rated electrical power and also how
to start-up with no AC power available.
Normal Operation on AC Start-Up:
• Verify that the unit is plugged into properly rated
electrical power.
• Position the System Power Switch to the ON
position.
The system will proceed through about a three-second
diagnostic where all the lights will sequence
ON then
OFF. The AC IN light will flash several times and the
audible alarm will give a short burst. The AC IN light
will then stay
ON and the battery level meter will light to
the current battery charge level. The INVERTER light
will come
ON. The LOAD I and LOAD II lights will come
ON and power will be available at all the output
receptacles. Actual load may be connected at any time
during this procedure, however, power is only available
when the light above either of the LOAD switches is
ON
continuously.
Battery Operation after AC Start-Up:
• Unplug the unit from the standard wall outlet.
The AC ON light will flash at two to three second
intervals. Within 5 seconds, the audible alarm will
sound at half-second intervals.
• Push and hold in the ALARM SILENT/TEST switch
until the audible alarm is inhibited.
If operation were to continue in this mode, the
BATTERY LEVEL meter would start to turn
OFF, one
light at a time starting from the top. Once the last red
light is left and the preprogrammed battery availability
time (usually about 2 minutes) is reached, the alarm will
sound in a constant tone. Had the alarm been
previously silenced, it would reactivate to alert the user
of limited operation. This alarm can also be silenced as
before. If the unit is allowed to operate further, it will
time out and shut off completely. If power were to
return, the unit will automatically restart and return to
the condition it was in at the moment it went into Battery
Mode.
DC Start Operation (Cold Start)
If no utility power is available at the time backup power
is required, the unit may be started to accomplish
abbreviated tasks. The limitations of the battery
prevent extended operations at full load.
• Position the System Power Switch to the ON
position.
• Push and hold in the COLD START switch until the
audible alarm beeps.
The unit will start up similarly to normal AC start-up
except the AC IN LED will continue to flash. The LOAD
outputs will come up in the
OFF mode when using the
COLD START feature.
Loading the System
The system can be loaded up to full rated load. As load
is applied, the LOAD METER will start to turn
ON. Once
full load is achieved, the full LOAD METER should be
lit. As additional load is applied, the top red
OVERLOAD LED will come
ON. If too much overload is
applied, the audible alarm will sound. If this increased
load is not removed within five seconds, the unit will
discontinue output operation and latch into an alarm
condition. The audible alarm will continue to sound and
the ALARM LED will light. Reducing the load and
cycling the System Power Switch
OFF then ON can reset
the system.
Programming the Outputs:
The outputs on startup can be programmed
ON or OFF.
The default mode is programmed to turn both load
circuits
ON whenever you power up the UPS on AC
startup. They will stay energized until you turn
OFF the
UPS, the batteries run down during a power outage or if
the appropriate load button is pressed.
To program both loads to be
OFF when the UPS is
turned
ON:
• Turn the UPS OFF.
• Turn the UPS ON while pressing and holding the
ALARM SILENT/TEST switch.
• The UPS will come ON with both loads OFF and will
remember this setting each time the unit is turned
ON.
To program both loads to come ON:
• Turn the UPS OFF.
• Turn the UPS ON while pressing and holding both
LOAD I and LOAD II switches (this definitely
requires both hands). The UPS will remember this
combination the next time it is powered
ON.
To program LOAD I or LOAD II to come
ON individually
at startup:
• Turn the UPS OFF.
• Turn the UPS ON while pressing and holding either
LOAD I or LOAD II switches.
The UPS will remember this combination the next time
it is powered
ON.
