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.
• Connect Cable from Aux. Battery Box to UPS.
• Position the Input Circuit Breaker to the ON
position.
• Position the System Power Switch to the ON
position and the BYPASS SWITCH to the INV
position. You will now have Bypass power at the
receptacles.
The system will proceed through about a three
second diagnostic where all the L.E.D.s will sequence
ON then OFF. The AC IN L.E.D. will flash several
times and the audible alarm will give a short burst.
The AC IN light L.E.D. will then stay
ON and the
battery level meter will light to at least an 80% level.
The INVERTER L.E.D. will come
ON and inverter
power will now be available at all the output
receptacles. The LOAD I and LOAD II will come
ON.
Actual load may be connected at any time during this
procedure, however inverter power is only available
when the L.E.D. 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 In L.E.D. 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
L.E.D. at a time starting from the top. Once the last
L.E.D. is left, the alarm will sound in a constant tone.
Had the alarm been previously silenced, it would still
re-enable 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 shut off the
loads. 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 L.E.D. will continue to flash. The
LOAD outputs will come up in the
OFF mode when
using the COLD START feature. You must press and
hold the LOAD I or LOAD II switch to activate the
inverter.
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. The LOAD METER will not work when you are in
a “Manual Bypass”. Once full load is achieved, the
full LOAD METER should be lit. As additional load is
applied, the top red OVERLOAD L.E.D. 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
L.E.D. 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
LOAD I OR II 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.
