S4KC SERIES USER MANUAL | 9
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 a 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 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 Rectier/Power Factor Correction (PFC) Circuit
In normal operation, the rectier/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 eciently as possible by the UPS.
• The amount of distortion reected on the utility is reduced.
This results in cleaner power being available to other devices in the building not being 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.

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 eciency 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 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 utility supply.

the front panel and rear panel of the UPS. Blocking the air inlets reduces ventilation and heat dissipation, shortening the
service life of the unit.
Maintain an ambient temperature range of 0°C to +40°C (+32°F to +104°F).
NOTE: UPS operation in sustained temperatures outside the range of 15°C to 25°C (59°F to 77°F) reduces battery life.
5.2 Installing the Main Cabinet
The S4KC may be installed as a tower conguration or in a rack, depending on available space and use considerations.
Determine the type of installation and follow the appropriate instructions in either “5.2.1 Tower UPS Installation or “5.2.2
Rack-Mount UPS Installation”.
5.2.1 Tower UPS Installation
To install the S4KC as a tower:
1. Take out support bases from the accessories bag (see Figure 9).

2. If optional external battery cabinets will be connected to the UPS, take out the spacers shipped with the battery
cabinet.
3. Connect the spacers and the support bases as shown in Figure 9. Each S4KC needs two assembled support bases, one
in the front and one in the rear.

5.2.2 Rack-Mount UPS Installation
When using the S4KC in a rack-mount conguration, the UPS must be supported by a slide kit, xed rails, or a shelf.
When using the optional Adjustable Rack-Mount Kit, you will use the instructions below. The gures accompanying “5.2.3
Installing the Adjustable Rack-Mount Kit” show the positioning of the rack-mounting brackets. SolaHD recommends taking
the internal batteries out of the UPS during rack installation. This will make the UPS cabinet lighter and easier to handle.
! CAUTION
The UPS is heavy (see “12.0 Specications”). The UPS must be installed as close to the bottom of the rack as possible.
If placed too high, it can make the rack top-heavy and prone to tipping over.
5.2.3 Installing the Adjustable Rack-Mount Kit (Sold Separately)
This kit contains parts needed to mount both models of the UPS and the external battery cabinets into EIA310-D standard
four-post racks that are 18–32 in. deep (457–813 mm). The weight limit per pair of adjustable rack-mounting brackets is
200 lb. (91 kg).
Parts included:
• Two rear bracket members, two front bracket members, two inner bracket members
• Sixteen M4 machine screws, eight M4 locking hex nuts
• Eight M5 machine screws
Tools needed for installation:
• Phillips screwdriver
• 7 mm wrench
The adjustable rack-mounting brackets (Part#: SRS18-32) feature retaining latches to prevent users from inadvertently
sliding the UPS or battery cabinet out of the rack.
To install the rack-mount brackets:
1. Unpack two rack-mounting bracket assemblies and mounting hardware from this kit. Bracket assemblies are inter-
changeable between left-hand or right-hand.
Remove the inner member from each bracket assembly as shown in Figure 12 by extending it to its outer-most position,
depressing the retaining latch and then pulling the inner member out of the bracket assembly.
