MAJOR COMPONENTS
Transient Voltage Surge Suppression (TVSS) & EMI/RFI
Filters
These UPS components provide surge protection and filter electro-
magnetic interference (EMI) and radio frequency interference (RFI).
They minimize surges or interference present in the mains line and
keep the sensitive equipment protected.
Automatic Voltage Regulator
The Automatic Voltage Regulator (AVR) protects connected equip-
ment from power spikes and other abnormalities by raising an under-
voltage (boost) and lowering an overvoltage (buck) as needed. This
keeps the UPS output voltage within the connected equipment’s toler-
ance and accommodates wide mains voltage fluctuations without uti-
lizing the batteries.
Bi-Directional Converter
In normal operation, the Bi-Directional Converter changes mains AC
power into regulated DC power to “float charge” the battery system.
This converter is continuously charging the battery whenever the UPS
is plugged into a power outlet and mains power is within acceptable
limits—even if the UPS is turned OFF.
When mains power fails, the Bi-Directional Converter draws energy
from the battery and inverts it into a regulated stepped sinewave sup-
plying power for equipment connected to the orange receptacles.
Battery
The S2K unit utilizes valve-regulated, nonspillable, lead acid batter-
ies. To optimize battery life, operate the UPS in an ambient tempera-
ture of 20°-25°C (68°-77°F).

INSTALLATION
This UPS is designed for data processing equipment. Maximum load
must not exceed that shown on the UPS rating label. Do not connect
equipment that could overload the UPS or draw half-wave current
from the UPS, for example: electric drills, vacuum cleaners, laser
printers or hair dryers. Your total load earth leakage current must not
exceed 3.5 mA. Most data processing equipment meets this require-
ment if you use no more than two pieces of equipment. If uncertain
about your load, consult your local distributor, Sola/Hevi-Duty repre-
sentative, or Sola/Hevi-Duty Technical Services.
1. Visually inspect the UPS for freight damage. Report damage to the
carrier and your local distributor, Sola/Hevi-Duty representative, or

MODES OF OPERATION
Normal Mode
During Normal mode operation, the S2K unit supplies conditioned,
computer-grade power to the connected equipment: mains power
passes through the TVSS circuitry and the EMI/RFI filters and then
through the Bi-Directional Converter to connected equipment.
When the UPS is in Normal mode, the Mains Indicator illuminates
green.
The S2K unit continuously monitors the batteries to maintain them in
a fully charged state. The battery charger operates whenever AC
power is present, even if the UPS is switched off. By default, the UPS
is set to perform an automatic battery test after it has been operating
continuously for two (2) weeks. The interval at which the UPS will
perform a battery test can be configured via MultiLink.
Buck/Boost Mode
The Automatic Voltage Regulator (AVR) circuitry compensates for
fluctuations in mains power, such as voltage surges and sags. When
the S2K unit detects an abnormality, it raises the undervoltage
(boost) or lowers the overvoltage (buck) as needed. The AVR operates
automatically and maintains the output voltage to the connected criti-
cal equipment, without utilizing the batteries.
When the UPS is in Buck/Boost mode, the Mains Indicator illumi-
nates amber.
Mains Indicator (Green)
Mains Indicator (Amber)

16
Battery Mode
The UPS switches to Battery mode in the event of an extreme voltage/
frequency condition or complete mains failure. The battery system
supplies power through the Bi-Directional Converter to generate
power for connected equipment.
When the UPS is in Battery mode, the Battery Indicator illuminates
green and an alarm sounds every 10 seconds.
When a low battery condition occurs, the Battery Indicator changes to
flashing amber and the alarm sounds every half-second. Low battery
warning is defaulted to two (2) minutes but can be configured via Mul-
tiLink. For more information, refer to Troubleshooting section.
!CAUTION
Turning off the UPS while in either Normal mode or Battery
mode will result in the loss of output power.
NOTE
Once mains power is restored, the UPS resumes normal
operation. At this time, the battery charger begins recharging
the battery. The UPS is capable of OFF-State charging, i.e.,
with mains power, the UPS will charge the batteries as long
as it is plugged in.
