Figure 3: Operating principle diagram
The UPS is composed of utility input, SPD and EMI/RFI filters, rectifier/PFC, inverter, battery charger, DC-DC converter,
battery, dynamic bypass, and UPS output.
1.4.1 Surge Protection Device (SPD) & EMI/RFI Filters
The S4K2UC has surge protection and filters that protect the connected load from power surges, electromagnetic interference (EMI) and radio frequency interference (RFI). These features can minimize any surges or interference present in
the utility power. The filters also prevent surges or interference generated by the UPS from adversely affecting devices
connected on the same branch as the UPS.
1.4.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the S4K2UC’s rectifier/power factor correction (PFC) circuit converts utility 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:
•
Efficient power use by the UPS
•
Reduced reflected harmonics
This results in cleaner power being available to other devices in the building not protected by the S4K2UC.
S4K2UC SEries user manual | 13
1.4.3 Inverter
In normal operation, the S4K2UC’s inverter utilizes the DC output of the PFC rectifier to produce precise, regulated sine
wave AC power. When utility power fails, the inverter receives DC power from the DC-DC converter. In either operation
mode, the UPS inverter is online, continuously generating clean, precise, regulated AC output power.
1.4.4 Battery Charger
The battery charger utilizes energy from the utility power and precisely regulates it to continuously float charge the
batteries. The batteries are being charged whenever the S4K2UC is plugged in, even when the UPS is not turned on.
1.4.5 DC-DC Converter
The DC-DC converter raises the DC voltage from the battery to the optimum operating voltage for the inverter. This
allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability.
1.4.6 Battery
The S4K2UC uses valve-regulated, non-spillable, lead acid batteries. To maintain battery design life, operate the S4K2UC
in an ambient temperature of 0°C to 25°C (32°F to 77°F).
NOTE: Optional external battery cabinets are available to extend battery run times.
1.4.7 Dynamic Bypass
The S4K2UC provides an alternate path for utility power to the connected loads in the unlikely event of a UPS malfunction. Should the S4K2UC have an overload, overtemperature or UPS failure condition, the UPS automatically transfers the
connected loads to bypass.
NOTE: The bypass power path does not protect the connected loads from disturbances on the utility.
1.5 Operating Modes
The UPS operating modes include: Utility (VAC) Mode, Bypass Mode, Battery Mode, Battery Recharge Mode, and
Frequency Converter Mode. For descriptions of indicators and control buttons, refer to “3.0 Controls & Indicators”.
1.5.1 Utility (VAC) Mode
During Utility (VAC) Mode, utility power provides energy to the S4K2UC. The filters, PFC rectifier and the inverter process
this power to provide computer-grade power to connected loads. Meanwhile, the UPS maintains the batteries in a fully
charged state.
1.5.2 Manual Bypass Mode
Manual Bypass Mode occurs when the Standby/Manual Bypass button is pressed and held for about 2 seconds while
the S4K2UC is in Utility (VAC) Mode. Bypass operation is indicated by an audible alarm and illuminated amber bypass
indicator. (If other indicators are illuminated, refer to “8.0 Troubleshooting”). During Manual Bypass Mode, utility power
bypasses the inverter and provides energy to the connected load.
!
CAUTION
Turning off the UPS in Manual Bypass Mode will result in loss of output power and dropped loads.
14 | 1.0 Product Description
1.5.3 Battery Mode
The S4K2UC enters Battery Mode when utility power fails or is outside acceptable values. The battery system supplies
power through the DC-DC converter to the inverter to generate clean AC power for the connected loads.
When the S4K2UC enters Battery Mode, the UPS sounds a half-second beep at 10-second intervals.
When approximately 2 minutes of run time remains, the beeps sound every 5 seconds to warn that the battery is getting
low (this low battery warning is user-configurable).
In Battery Mode, the AC Input indicator goes off and the Battery Level indicators illuminate. Each Battery Level indicator
represents a 20% capacity level. As capacity decreases, fewer indicators remain illuminated. Refer to “8.0 Troubleshooting”.
For approximate battery run times, refer to “9.0 Specifications—Table 13”. The times in Table 13 are approximate. They are
based on resistive loads and an ambient temperature of 25°C (77°F). To increase this time, turn off non-essential loads
(such as idle computers and monitors) or add optional external battery cabinets.
!
CAUTION
Turning off the S4K2UC while in Battery Mode will result in loss of output power. If the UPS is turned off manually, it
must be manually restarted after utility power returns. If the UPS is turned off by a communication signal or because
the batteries are depleted, it will operate as selected in the configuration program for Auto-Restart (refer to “5.2.1
Configuration Program”).
1.5.4 Battery Recharge Mode
Once utility power is applied to the S4K2UC, the battery charger begins charging the batteries.
1.5.5 Frequency Converter Mode
All models of the S4K2UC are capable of frequency conversion. Frequency Conversion Mode can be selected using the
configuration program. Allowable frequency operating modes include:
•
Auto Sensing — 50 Hz or 60 Hz — Bypass Enabled
•
Auto Sensing — 50 Hz or 60 Hz — Bypass Disabled
•
Frequency Converter — 50 Hz — Bypass Disabled
•
Frequency Converter — 60 Hz — Bypass Disabled
NOTE: The default for all models of the S4K2UC is “Auto Sensing — 50 Hz or 60 Hz — Bypass Enabled.”
!
CAUTION
Do not touch the AC input receptacle when the UPS is operating. AC input voltages may still be present, even when
the AC input indicator is off.

NOTE: Up to four external battery cabinets can be connected to the UPS. Each cabinet will increase the battery recharge time.
2.5 Cable Connection
The S4K2UC rear panel has an input cable and plug, output receptacles and output cables (S4K2U3000 models only).
Refer to “1.3.2 Rear Panel Features” for details. The battery cables are supplied with the battery cabinet.
2.5.1 Connecting Input Plug & Loads
NOTES:
• Ensure that all the loads are turned off.
•
Prepare an input power supply that is properly protected by a circuit breaker in accordance with national and local
electrical codes. The wall receptacle must be grounded.
•
The plug on the power supply cord is intended to serve as the disconnection device. The socket-outlet must be
installed near the equipment and must be easily accessible.
•
SolaHD recommends installing an upstream circuit breaker of the same series as the S4K2UC’s input circuit breaker.
The upstream breaker should be the same or higher capacity than the UPS input circuit breaker. The specification of
input circuit breaker on the rear panel of UPS is shown in Table 2.

2.5.2 AC Input/Output Hardwire Installation
!
CAUTION
This installation must be performed by electrical personnel and wired in accordance with local/national electrical codes.
Installation Considerations:
On start-up, the UPS will take a half cycle inrush current of up to three times the rated current. This must be taken into
account when selecting the overload protection device at the input utility supply distribution point. To avoid random
tripping on startup, we recommend that input utility supply be protected with a MCB (Mechanical Circuit Breaker)
capable of withstanding this initial inrush.
The utility input supply cable must be connected to the UPS via a wall mounted double pole circuit breaker. The UPS
output port must also be protected with a double pole circuit breaker connected to the load, rated to carry the input
current, and be capable of breaking the maximum prospective short circuit current of this branch circuit. The breakers
are to be mounted within six feet of the UPS and be readily accessible to the operator. Please refer to Table 3 for breaker
specifications.
High-quality ground (earth) connections are required for the equipment ground conductors (protective earth) and
grounding electrode conductor (power system earth connection) to reduce electrical noise and provide for safe operation of the UPS and connected loads. Conduit used alone without a grounding conductor wire is not an acceptable
connection. Size ground (protective earth) conductors equal to circuit conductors. For wiring information, please refer to
Table 3.

the load is unprotected from disturbances and power outages. Do not replace the battery while the UPS is operating in
Battery Mode. This will result in a loss of output power and will drop the connected load.

7.2 Battery Charging
The batteries are valve-regulated, non-spillable, lead acid and should be kept charged to attain their design life. The
S4K2UC charges the batteries continuously when it is connected to the utility input power.
If the S4K2UC will be stored for a long time period of 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.
7.3 Precautions
Although the S4K2UC has been designed and manufactured to ensure personal safety, improper use can result in electrical shock or fire. To ensure safety, observe the following precautions:
•
Turn off and unplug the S4K2UC before cleaning it
•
Clean the UPS with a dry cloth—do not use liquid or aerosol cleaners
•
Never block or insert any objects into the ventilation holes or other openings of the S4K2UC
•
Do not place the S4K2UC power cord where it might be damaged
7.4 Checking UPS Status
SolaHD recommends checking the UPS operation status every six months.
•
Check if the UPS is faulty: Is the Fault Indicator on? Is the UPS sounding an alarm?
•
Check if 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 if 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 local SolaHD representative or SolaHD Technical Support.
7.5 Checking UPS Functions
NOTE: UPS function check procedures may interrupt power supply to the connected load. Back up all critical load data
before conducting the UPS functions check.
SolaHD recommends checking the UPS functions once every six months.
Procedures are as follows:
1. Press the Standby/Manual Bypass button to check whether the alarm and indicators are normal.
2. Press the On/Alarm Silence/Manual Battery Test button to check again whether the indicators are on and the UPS is
operating normally.
3. Press the On/Alarm Silence/Manual Battery Test button for 3 seconds after Inverter Mode; the UPS should initiate
battery self-test. Check to determine whether the battery is operating normally. If not, stop and contact your local
SolaHD representative or SolaHD Technical Support.
