2.0 INTRODUCTION AND SYSTEM DESCRIPTION
Congratulations on your choice of the Online 10Kva RT 127V Uninterruptible
Power Supply (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 is
subject to voltage sags, spikes or complete power failure that may interrupt computer operations,
cause data loss or even damage equipment. The UPStation 10Kva RT protects equipment
from these disturbances.
The 10Kva RT is a compact, on-line UPS. An on-line UPS continuously conditions
and regulates its output voltage whether utility power is present or not. It supplies connected
equipment with clean sinewave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the 10Kva RT 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/Battery Test button, a Standby button, user configurable program and two
levels of alarms when the unit is operating on battery.
The 10Kva RT 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
Winpower software. Winpower software can also control UPS operation remotely.

3.0 SYSTEM DESCRIPTION
3.1 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
utility line and keep the sensitive equipment protected.
3.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility 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 utility power is used as efficiently as possible by the UPS.
• The amount of distortion reflected on the utility is reduced.
This results in cleaner power being available to other devices in the building not being protected by
the 10Kva RT.
3.3 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 utility power failure, the inverter
receives 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.
3.4 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 10Kva RT is plugged in,
even when the UPS is not turned on.

3.5 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 efficiency and voltage, thus increasing reliability.
3.6 Battery
The 10Kva RT utilizes valve-regulated, nonspillable, flame retardant, lead acid
batteries. To maintain battery design life, operate the UPS in an ambient temperature of 68°F to 77°F
(20°C to 25°C). Optional external battery cabinets are available to extend battery run times.
3.7 Static Bypass
The 10Kva RT 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
UPS failure condition, the UPS automatically transfers the connected load to bypass. Bypass
operation is indicated by an audible alarm and illuminated amber Bypass indicator (other indicators may
be illuminated to indicate the diagnosed problem).
The user may manually transfer the connected load from the inverter to bypass by pressing the
Standby button once.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances
on the utility supply.

6.1.2 Installing the Adjustable Rack-Mount Kit
This kit contains parts needed to mount several different models of UPS and external battery
cabinets 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 270 pounds (123 kg).
RT 10Kva rack-mount bracket kit, includes:
Tools needed for installation are:
•one Phillips screwdriver
•one 7mm wrench
The adjustable rack-mounting brackets 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
in at right by extending it to its outermost position,
depressing 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 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 top and bottom holes of the return flange on each
front member. Make sure 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 1" long
bead of grease 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.
!CAUTION
Lifting equipment into the rack may be a two-person
job, depending on the weight of the equipment. (See
equipment’s user manual.)

6.2 External Battery Cabinet Installation
Optional RT 10Kva 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.
The external battery cabinet frame and battery kits are shipped separately. This 4U cabinet arrives
without internal batteries to lighten the cabinet for easier installation. Once the cabinet has been
placed in its final floor or rack position, the internal batteries may be installed.
When the external battery cabinet is received, it should be inspected for freight damage. Report
damage to the carrier and your local distributor or sales representative.
To install an external battery cabinet:
1. For slide rail installations, first remove the top bezel. Optional rack-mount handles are shipped
with the external battery cabinet and may be installed now.
2. Fasten the slides into position with the screws according to the instructions included with the
slide rails.
3. Use the enclosed support bases for the tower option to
prevent the assembly from tipping over. One additional set
of support base extensions ships with each external
battery cabinet.
4. Install the two battery packs and secure with the two
brackets supplied.
5. Connect the two slotted battery cables.
6. Attach the battery cover plate and the two front bezels.
7. Connect the supplied external battery cabinet cables to
either set of connectors on the rear of the external battery
cabinet, then to the rear of the UPS.
8. The UPS is now equipped with additional backup battery
run time. For approximate battery run times, refer to Table
6 - Battery run times in this manual.
9. Do NOT turn on the battery cabinet circuit breaker at this
time. Please complete the remainder of the installation first.
!CAUTION
The external battery cabinet(s) are heavy (see 14.0 - Specifications). External battery
cabinets can be used in rack-mount or tower configuration. Take proper precautions when
lifting them.
!CAUTION
Verify that the battery cabinet circuit breaker is in the OFF position. Dot no energize the
battery cabinet at this time. When installation is complete, you will be instructed to turn on
the circuit breaker.
