Important Notice
The UPS ground (earth) conductor carries leakage current from the loads in addition to any
leakage current generated by the UPS. This UPS generates no more than 1 mA of current. To
limit the total leakage current to 3.5 mA, the load leakage must be limited to 2.5 mA. The threewire receptacle that you plug the UPS into must have a good (low-impedance) ground (protective earth) connection to provide a safe path for leakage current.

Quick Startup
1
Your SOLA520 Rackmount UPS has a removable power cord. Connect the power cord to
the back of the unit and plug the UPS into a wall outlet.
2
Let the unit charge the battery for at least 3 hours (7 hours for 1425 VA model if it is fully
loaded). You may use the unit while the battery charges, but the battery backup runtime will
be reduced until the battery is fully charged.
3
Start the SOLA520 Rackmount by pressing and holding the On/Standby button (large
button in the center of the front panel) in for about one second. Note: To turn the unit either
on or off, the On/Standby button must be pressed for about one second.
3.a.When it starts, the unit beeps and lights the front panel lights, turns them off, and lights
them again. Next, the SOLA520 Rackmount applies AC output to the back panel
receptacles.It does a brief self test, turning various front panel lights off and on.
3.b.After 30 seconds or less, the self test is complete. The top and bottom green lights will
come on and remain on. If the unit beeps, or if the top light does not remain on even
though input power is available from the wall outlet, go to the Troubleshooting section.
4
Switch off the equipment you want to protect, and plug each load into the outlets on the
back of the SOLA520 Rackmount.
5
Switch on the protected equipment, one load at a time. If the UPS beeps an alarm when you
start your equipment, the UPS may be overloaded. See the Troubleshooting section.
The bottom four lights on the front of the UPS show the % of load capacity that your equipment is using. See Symbols, LEDs and Audible Beeps Section for more information.
6
The RJ-11 or RJ-45 Surge Protection
jacks will protect equipment that uses
an RJ-11 or RJ-45 connection. Plug
the 10BASE-T network connection
into the surge protection jack labeled
“IN” on the back of the SOLA520
Rackmount. Plug the protected equipment into the surge protection jack
labeled “OUT.” Network cabling is not
provided. This connection is optional. It is not needed to use the SOLA520 Rackmount.

Symbols, LEDs and Audible Beeps
The front panel indicators (LEDs) and an audible beep indicate the unit status. The unit beeps
whenever the unit is on battery power or an alarm is present. See Table 2 for information about
beep coding. In the figure below, bucking means that SOLA520 Rackmount is reducing high
input voltage, and boosting means SOLA 520 Rackmount is increasing low input voltage.
If your SOLA520 Rackmount runs on batteries frequently because the input utility line varies
often, you may want to adjust your SOLA520 Rackmount to accept wider voltage variations
before switching to batteries. Appendix A describes how to adjust the SOLA520 Rackmount
from the front panel in response to specific utility power problems. You should have an
electrician check your nominal line voltage and determine if the problem is due to a “Surge”
(high) voltage or “Brownout” (low) voltage. Changing the setting without this knowledge could
make the problem worse.
Steady: SOLA 520 is operating on AC line.
Blinking: SOLA 520 is bucking or boosting input AC line.

Replacing the Batteries
The SOLA520 Rackmount batteries are user-replaceable and can be replaced while the SOLA
520 Rackmount has AC input applied and powers the loads. This means that, if necessary, you
can replace the batteries while the UPS is running. Before you replace the batteries, make sure
that you read the safety information below.
Note: If you have a power outage while you are replacing the batteries, the UPS will not be
able to run on battery power and your protected equipment will shut down.
CAUTION!
The batteries used in the UPS and battery pack can produce dangerous voltage and high
current. Therefore, the batteries may cause severe injury if their terminals contact a tool or the
UPS cabinet. Be very careful to avoid electrical shock and burns from contacting terminals
while you replace the batteries.
Batteries contain caustic acids and toxic materials and can rupture or leak if mistreated.
Remove rings and metal wristwatches or other jewelry. Do not carry metal objects in your
pockets: these objects could fall into the UPS.
Never allow any tool to contact both a battery terminal and the UPS cabinet or another
battery terminal. Do not lay tools or metal parts on top of batteries.
To ensure continued superior performance of your UPS and to maintain proper charger
operation, you must replace the UPS batteries with the same number and type of batteries.
These batteries must be the same type as the original batteries: valve-regulated, low
maintenance. The replacement batteries should have the same voltage and ampere-hour rating
as the original batteries.
Assume that old batteries are fully charged. Use the same precautions you would use when
handling a new battery. Do not short battery terminals with a cable or tool! Batteries contain
lead. Many areas have regulations about disposing of used batteries. Please dispose of old
batteries properly. DO NOT dispose of batteries in a fire because the batteries could explode.
Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may
be toxic.
This equipment may produce ozone. Take precautions to ensure that the concentration of
ozone is limited to a safe value (0.1 ppm {0.2 mg / m3} calculated as an 8-hour time-weighted
average).

Appendix A: Adjusting Voltage Settings
When the unit is not sounding an alarm,you can use the Alarm/Program button shown below to
change the following:
• Nominal Voltage — The normal voltage the SOLA520 Rackmount is programmed to expect, and
the nominal UPS output voltage under line loss conditions.
• Buck — The input voltage at which the SOLA 520 Rackmount decreases voltage before providing
output because the input voltage is too high.
• Boost — The input voltage at which the SOLA 520 Rackmount increases voltage before providing
output because the input voltage is too low.
• Transfer to Inverter — The point at which the SOLA 520 Rackmount switches to inverter (battery
power), either because AC input voltage is very low or because it is very
high.
Note: Make sure you want to change these values before
you start the procedure below. Once you press the
button shown for 10 seconds, the values will change

• When input voltage drops to 221, the SOLA 520 Rackmount begins to increase (boost) the
output voltage.
• 240 is the nominal or expected input voltage.
• When input voltage rises to 254, the SOLA520 Rackmount begins to decrease (buck) the
output voltage.
• With 283 volts input or higher, the SOLA520 Rackmount switches to battery power.
