1.0 Introduction
Congratulations on your choice of the SolaHD S4K5U6K5C Uninterruptible Power System (UPS).
The S4K5U6K5C is a compact, on-line Uninterruptible Power System (UPS) which continuously conditions and regulates
its output voltage, whether mains power is present or not. It is designed to supply microcomputers and other sensitive
equipment with clean sine wave power.
The S4K5U6K5C 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 S4K5U6K5C 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.

2.1 Surge Protection Devices (SPD) & EMI/RFI Filters
These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency
interference (RFI). They minimize any surges or interference present in the mains line and keep the sensitive equipment
protected.
2.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts mains 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 mains power is used as efficiently as possible by the UPS.
•
The amount of distortion reflected on the mains is reduced.
This results in cleaner power being available to other devices in the building which are not protected by the UPS.
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 mains power failure, the inverter receives its required energy from the battery
through the DC-DC converter. In both modes of operation, the UPS inverter is on-line and continuously generating clean,
precise, regulated AC output power.
S4KC SEries user manual | 11
2.4 Battery Charger
The battery charger utilizes energy from the mains power and precisely regulates it to continuously float charge the
batteries. The batteries are being charged whenever the UPS is connected to mains power.
2.5 DC-DC Converter
The DC-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 efficiency and voltage, thus increasing
reliability.
2.6 Battery
The UPS 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 11.
2.7 Dynamic Bypass
The UPS provides an alternate path for mains 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 the 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 mains supply.

Using the configuration 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 11 shows the estimated battery backup times at
different loads.

12.1 Auto-learning Battery Backup Times
As batteries age, the estimated backup times may become less accurate. The S4K5U6K5C 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 different 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 modified.
If the configuration program is used to change the number of battery Cabinets, then the values in Table 11 will be
restored. This will override any value that is auto-learned.
