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
three-wire 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
1If your SOLA 325 UPS has a removable power cord, connect the power cord to the back of the unit. Plug the UPS into a wall outlet. Even if the UPS is turned off, the battery charger
will operate when input power is applied to the UPS.
2Let the unit charge the battery for at least 8 hours. You may use the unit while the battery charges, but the battery backup runtime will be reduced until the battery is fully charged.
3Note: The On/Off button must be pressed and held for about one second to turn the SOLA 325 unit on or off. To start the unit, press and hold the On/Off button (the bottom button on
the front panel). When the unit starts, it will beep, then light all of the front panel lights for a
moment, and then light them one at a time. Next, the UPS will do a battery test. While it
does this test, the battery light , and other lights are on that indicate the amount of charge in
the battery. After the battery test, the top green light should 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.
4Switch off the equipment you want to protect, and plug it into the outlets on the back of the SOLA 325.
5Switch on the protected equipment, one 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 the UPS’s power that your
equipment is using. See Symbols, LEDs and Audible Alarms Section for more information.
6The Surge Protection jacks will protect network equipment that uses an RJ-45 connection. Plug the 10BASE-T network connection into the
surge protection jack labeled “IN” on the back of the SOLA 325. 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 SOLA 325.
7Please fill out the warranty registration card and return it to your local SOLA office.

teries” on page 10.
To silence an alarm, press the alarm silence button on the front panel (see Page 3 for the location
of this button). The beep will stop, but the alarm light will stay on. Note: Silencing the alarm
does not solve the problem that caused it. See Tables 3 and 4.
If your SOLA 325 runs on batteries frequently because the input utility line varies often, you may
want to adjust your SOLA 325 to accept wider voltage variations before switching to batteries.
Appendix A describes how to adjust the SOLA 325 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.

Replacing the Batteries
SOLA 325’s batteries are user-replaceable and can be replaced while the SOLA 325 has AC
input applied and powers the load. 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-weight-
ed average).
