1.0 INTRODUCTION
Congratulations on your choice of the Sola/Hevi-DutyS4K5U6000-5 Uninterruptible Power System
(UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment.
Upon generation, AC power is clean and stable. However, during transmission and distribution it
may be subject to voltage sags, spikes, or complete power failure that may interrupt computer opera-
tions, cause data loss, or even damage equipment. The S4K5U protects equipment from these distur-
bances.
The S4K5U comes in nominal power ratings of 4500 VA and 6000 VA. Complete model specifications
appear at the end of this manual.
The S4K5U is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its out-
put voltage, whether mains power is present or not. It supplies connected equipment with clean sine-
wave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the S4K5U features a light-emitting diode (LED) display to indicate both load per-
centage and battery capacity. It also provides self-diagnostic tests, a combination ON/Alarm Silence/
Manual Battery Test button, a Standby button, user configurable program, and two levels of alarms
when the unit is operating on battery.
The S4K5U has an interface port for communication between the UPS and a network server or other
computer systems. This port provides detailed operating information including voltages, currents,
and alarm status to the host system when used in conjunction with Sola/Hevi-Duty MultiLink™ soft-
ware. MultiLink software can also remotely control UPS operation.

2.0 SYSTEM DESCRIPTION
2.1 Transient Voltage Surge Suppression (TVSS) and 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 waveshape of the input current
used by the UPS is near ideal. Extracting this sinewave 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 not being protected by
the S4K5U.
2.3 Inverter
In normal operation, the inverter utilizes the DC output of the power factor correction circuit and
inverts it into precise, regulated sinewave AC power. Upon a mains power failure, the inverter
receives its required energy from the battery through the DC to DC converter. In both modes of oper-
ation, the UPS inverter is on-line and continuously generating clean, precise, Regulated Ac Output
Power.
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 S4K5U is connected to
mains 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 opti-
mum operating voltage for the inverter. This allows the inverter to operate continuously at its opti-
mum efficiency and voltage, thus increasing reliability.
2.6 Battery
The S4K5U utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design
life, operate the UPS in an ambient temperature of 20°C to 25°C (68°F to 77°F). Optional external
battery cabinets are available to extend battery run times.
2.7 Dynamic Bypass
The S4K5U 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 UPS failure condition, the
UPS automatically transfers the connected load to bypass. Bypass operation is indicated by an audi-
ble alarm and illuminated amber Bypass LED (other LEDs may be illuminated to indicate the diag-
nosed problem). To manually transfer the connected load from the inverter to bypass, press the
Standby button once.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances
in the mains supply.

5.0 INSTALLATION AND CONFIGURATION
Do NOT attempt to start the UPS, turn on any circuit breaker or energize the input power until
instructed to do so in 6.0 - Initial Start-Up and Electrical Checks.
Visually inspect the UPS for freight damage. Report any damage to the carrier and your local dealer
or Sola/Hevi-Duty representative.
Install the S4K5U indoors in a controlled environment, where it cannot be accidentally turned off.
Place it where air flows unrestricted around the unit. The installation location must be free of water,
flammable liquids, gases, corrosives and conductive contaminants. Maintain a minimum clearance of
100mm (4 inches) in the front and rear of the UPS. Maintain an ambient temperature range of 0 to
40°C (32 -104°F).
5.1 Install the Main Cabinet
The S4K5U may be installed in either a tower configuration or in a rack, depending on available
space and use considerations. Determine the type of installation and follow the appropriate instruc-
tions in either 5.1.1 - Tower UPS Installation or 5.1.2 - Rack-Mount UPS Installation.
5.1.1 Tower UPS Installation
When using the S4K5U in a tower configuration, use the included support base (shown below, left) to
stabilize the UPS. If any external battery cabinets are added, they will include spacers to accommo-
date the additional cabinets (shown below, right).
Figure 5 Tower-use support bases, spacers for external battery cabinets
5.1.2 Rack-Mount UPS Installation
When using the S4K5U in a rack-mount configuration, the UPS must be supported by a slide kit,
fixed rails or a shelf.
When using the optional Adjustable Rack Mount Kit, you will use the following instructions. The fig-
ures accompanying 5.1.3 - Installing the Adjustable Rack-Mount Kit—Sold Separately shows
the positioning of the rack-mounting brackets. Taking the internal batteries out of the UPS during
rack installation is recommended. This will make the UPS cabinet lighter and easier to handle.
!
CAUTION
The UPS is heavy (see 13.0 - Specifications (Sechnische Daten)). Take
proper precautions when lifting or moving it.
NOTE
UPS operation in sustained temperatures above 25°C (77°F) reduces battery life.
This device is intended for use in an Installation Category II environment.
!
CAUTION
Only three (3) M4 screws are used on the side of the S4K5U where the Power Distribution Box
is located. The fourth mounting hole is above the Power Distribution Box and is not used.

5.1.3 Installing the Adjustable Rack-Mount Kit—Sold Separately
This kit contains parts needed to mount several different models of UPS and external battery cabi-
nets into EIA310-D standard four-post racks that are 18-32" deep (457-813mm). The weight limit per
pair of adjustable rack-mounting brackets is 91 kg (200lbs.).
Parts included are:
Tools needed for installation are:
• one Phillips screwdriver
• one 7mm 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 (2) rack-mounting bracket assemblies and
mounting hardware from this kit. Bracket assemblies are
interchangeable between left-hand or right-hand.
Remove inner member of each bracket assembly as shown
at right by extending it to its outermost position, depress-
ing the retaining latch and then pulling the inner member
out of the bracket assembly.
2. Determine the height position inside the rack enclosure
where you want to mount the UPS or battery cabinet.
3. Install the rear member of each bracket assembly into the
rack enclosure with two (2) M5 screws provided in this kit
(see figure at right). The return flanges on the bracket
assembly fit to the inside of rack mounting rails. Insert
screws loosely (finger-tight) into the top and bottom holes of
the return flange on the rear member. Extend the bracket
assembly by sliding the front member forward until it
touches the front rack mounting rail. Insert two (2) M5
screws loosely (finger-tight) into the top and bottom holes of
the return flange on each front member. Make sure that the
bracket assemblies are at the same mounting height on all
four (4) rack mounting rails.

4. Get eight (8) M4 screws and eight (8) M4 nuts from the
hardware pack in this kit. Each nut has a locking, nylon
insert that begins gripping the screw when it is halfway
tight. Make sure to tighten the nut and screw completely to
ensure locking action. Fasten the rear member and the front
member together using (4) screws and (4) nuts per bracket
assembly as shown in at right. For maximum support, insert
fasteners for each bracket assembly as far apart as possible,
depending on rack depth, while still joining both members
(see figures at right). Check alignment of bracket assemblies
and TIGHTEN ALL SCREWS FROM Steps 2 and 3.
5. Prepare the UPS or battery cabinet (the “equipment”) for
rack mounting by following instructions in the equipment’s
user manual. The equipment may require additional parts to
be added or parts to be removed for rack mounting. After it is
prepared, lay the equipment in rack-mounting position.
Fasten the inner members from Step 1 to the equipment on
both sides as shown at right with eight (8) M4 screws
provided in the kit. Make sure retaining latch is near the rear
of the equipment as shown (see figure at right).
6. Open the grease packet provided in the kit. Apply a bead of
grease 25mm (1") long at four (4) places inside the bottom,
curved tracks of the front members as shown below right. The
grease will allow the equipment to slide into the bracket
assemblies more easily.
7. Insert the equipment, with inner members attached in
Step 5, into the bracket assemblies by inserting the top and
bottom edges of the inner members into the top and bottom
curved tracks of the front members and sliding the
equipment into the rack (see figure at right). Ends of inner
members are tapered to allow the rear of the equipment to be
angled upward before insertion, if space allows.
Then the rear, bottom edges of the inner members can be
placed into the front edge of the bottom tracks and the front
of the equipment can be tipped up so they are level to insert
the top edges of the inner members before sliding the equip-
ment into the rack (see figure below right). The equipment
should move smoothly into the bracket assemblies. If it does
not, recheck the alignment of the front and rear members
from Steps 2 and 3.
8. Secure the front of the equipment to the rack mounting rails
to prevent the equipment from sliding out of position. If
securing holes are provided on the front of the equipment
that align with the center holes on the return flange of the
front members, you can use the four (4) extra M5 screws
provided in the kit to secure the equipment. Otherwise, the
equipment should be secured to the front of the rack with
four (4) customer-supplied fasteners.
!
6.
CAUTION
Lifting equipment into the rack may be a two-person
job, depending on the weight of the equipment. Sola/
Hevi-Duty recommends taking the internal batteries
out of the UPS during rack installation. This will
make the UPS cabinet lighter and easier to handle.
The S4K5U weighs 67kg (151lb). For the battery
cabinet’s weight, see the unit’s user manual.

5.2 External Battery Cabinet Installation
Optional Sola/Hevi-Duty external battery cabinets may be connected to the UPS to provide additional
battery run time. External battery cabinets are designed to be placed on one side of the UPS or
stacked beneath the UPS.
1. Visually inspect the external battery cabinet for freight damage. Report damage to the carrier
and your local dealer or Sola/Hevi-Duty representative.
2. For slide rail installations, first remove the top/side fin. Top/side fin slides forward and then lift
up to remove. Optional rack-mount handles are shipped with the external battery cabinet and
may be installed at this time if desired.
3. Securing hardware and slide rails are sold separately. Please contact your local dealer or Sola/
Hevi-Duty representative for these additional options and any assistance needed. Fasten the
slides into position with the screws per the instructions included with the slide rails.
4. Use the enclosed support bases for the tower option to prevent tip-over. One additional set of
support base extensions ships with each external battery cabinet.
5. Connect the supplied external battery cabinet cable to the rear of the external battery cabinet,
then to the rear of the UPS.
6. The UPS is now equipped with additional backup battery run time. For approximate battery run
times, refer to Table 6.
