1.0 Introduction
Congratulations on your choice of the SolaHD S4KC Uninterruptible Power System (UPS). The S4KC is available in nominal
power ratings of 6,000 VA and 10,000 VA.
The S4KC is a compact, on-line Uninterruptible Power System (UPS) which continuously conditions and regulates its
output voltage, whether utility power is present or not. It is designed to supply microcomputers and other sensitive
equipment with clean sine wave power.
The S4KC features a light-emitting diode (LED) display to indicate both load percentage and battery capacity. It also
provides self-diagnostic tests, a combination ON/Alarm Silence/Manual Battery Test button, and a Standby/Manual
Bypass button.
The S4KC has an IntelliSlot® port for communication between the UPS and a network server or other computer system.
This port provides detailed operating information including voltages, currents, and alarm status to the host system when
used in conjunction with MultiLink®. MultiLink can also remotely control UPS operation.

These UPS components provide surge protection and lter both electromagnetic interference (EMI) and radio frequency
interference (RFI). They minimize any surges or interference present in the utility line and keep the sensitive equipment
protected.
2.2 Rectier/Power Factor Correction (PFC) Circuit
In normal operation, the rectier/power factor correction (PFC) circuit converts utility ac power to regulated dc power for
use by the inverter while ensuring that the wave shape of the input current used by the UPS is near ideal. Extracting this
sine wave input current achieves two objectives:
• The utility power is used as eciently as possible by the UPS.
• The amount of distortion reected on the utility is reduced.
This results in cleaner power being available to other devices in the building not protected by the S4KC.
2.3 Inverter
In normal operation, the inverter utilizes the dc output of the power factor correction circuit and inverts it into precise,
regulated sine wave ac power. Upon a utility power failure, the inverter receives its required energy from the battery
through the dc-to-dc converter. In both modes of operation, the UPS inverter is on-line and continuously generating
clean, precise, regulated ac output power.
Page 11
S4KC SERIES USER MANUAL | 11
2.4 Battery Charger
The battery charger utilizes energy from the utility power and precisely regulates it to continuously oat charge the
batteries. The batteries are being charged whenever the S4KC is connected to utility power.
2.5 Dc-to-Dc Converter
The dc-to-dc converter utilizes energy from the battery system and raises the dc voltage to the optimum operating
voltage for the inverter. This allows the inverter to operate continuously at its optimum eciency and voltage, thus
increasing reliability.
2.6 Battery
The S4KC utilizes valve-regulated, non-spillable, lead acid batteries. To maintain battery design life, operate the UPS in
an ambient temperature of -15°C to +25°C (+59°F to +77°F). Optional external battery cabinets are available to extend
battery backup times. For backup times, see Table 13.
2.7 Dynamic Bypass
The S4KC provides an alternate path for utility power to the connected load in the unlikely event of a UPS malfunction.
Should the UPS have an overload, overtemperature, or any other UPS failure condition, the UPS automatically transfers
the connected load to bypass. Bypass operation is indicated by an audible alarm and an illuminated amber Bypass LED.
(Other LEDs may be illuminated to indicate a diagnosed problem.) To manually transfer the connected load from the
inverter to bypass, press the Standby/Manual Bypass button once and hold it for about 2 seconds.
NOTE: The bypass power path does NOT protect the connected equipment from disturbances in the utility supply.

S4KC SERIES USER MANUAL | 41
10.2 Battery Charging
The batteries are valve-regulated, non-spillable, lead acid and should be kept charged to attain their design life. The S4KC
charges the batteries continuously when it is connected to the utility input power.
If the S4KC will be stored for a long time, SolaHD recommends connecting the UPS to input power for at least 24 hours
every four to six months to ensure full recharge of the batteries.
10.3 Precautions
Although the S4KC has been designed and manufactured to ensure personal safety, improper use can result in electrical
shock or re. To ensure safety, observe the following precautions:
• Turn o and unplug the S4KC before cleaning it.
• Wear rubber gloves, boots, and safety glasses.
• Clean the UPS with a soft, dry cloth. Do not use liquid or aerosol cleaners.
• Never block or insert any objects into the ventilation holes or other openings of the UPS.
• Do not place the S4KC power cord where it might be damaged.
10.4 Checking UPS Status
SolaHD recommends checking the UPS operation status every six months.
• Check whether the UPS is faulty. Is the Fault Indicator on? Is the UPS sounding an alarm?
• Check whether the UPS is operating in Bypass Mode. Normally, the UPS operates in Normal Mode. If it is operating
in Bypass Mode, stop and contact your local SolaHD representative or SolaHD Technical Support.
• Check whether the battery is discharging. When the utility input is normal, the battery should not discharge. If the
UPS is operating in Battery Mode, stop and contact your SolaHD representative or SolaHD Technical Support.
10.5 Checking UPS Functions
NOTE: UPS function check procedures may interrupt power supply to the connected load. Back up the load data before
conducting the UPS functions check.

Backup Time in Minutes
Using the conguration program, the user may specify the number of external battery cabinets attached to the UPS.
The factory default is programmed for internal batteries only. Table 13 shows the estimated battery backup times at
dierent loads.

12.1 Auto-learning Battery Backup Times
As batteries age, the estimated backup times may become less accurate. The S4KC is programmed to “learn” from a full
battery discharge and then modify the estimated backup time for the measured battery capacity. This can improve
accuracy and compensate for aging batteries or batteries that operate at dierent ambient temperatures.
The UPS will update the anticipated backup time calculation only under certain conditions:
• The UPS must have a steady load that is greater than 20%.
• The UPS must be at 100% charge at the start of a battery discharge.
• The battery discharge must continue uninterrupted until the batteries reach their end-of-discharge voltage.
If all conditions are not met, the backup time calculation will not be modied. If the conguration program is used to
change the number of battery cabinets, then the values in Table 13 will be restored. This will override any value that is
auto-learned.
