4.2 OPERATING PRINCIPLES
This manual describes the installation and operation of the uninterruptible power
supply (UPS) KESSUPS 92RT as devices that can be independently operated or
connected in parallel (for models > 3 kVA).
The KESSUPS 92RT series ensures optimum protection of any critical load,
maintaining the supply voltage of the loads between the speci ed parameters
without interruption during failure, deterioration or  uctuation of mains power,
and comes in a wide range of models (from 1 kVA to 6 kVA). Thus market-speci c
needs and wishes can be addressed in a more individual way.

11
KESS Power Solutions GmbH / www.kess.at / [email protected]
Thanks to their PWM (pulse width modulation) and double-conversion
technology, the KESSUPS 92RT series is compact, silent and offers high
performance.
The double converter principle eliminates all mains power disturbances. A
rectier converts the AC current of the mains into DC current. It maintains the
optimum battery charge level and powers the inverter, which in turn, generates
a suitable AC sine-wave voltage for continuously powering the loads. In the case
of failure the batteries supply clean power to the inverter.
The design and construction of the KESSUPS 92RT series has been carried out in
accordance with international standards.
In addition, models with power ratings greater than 3 kVA can be expanded with
the connection of additional modules with the same power in parallel to obtain
N+X redundancy or an increase in the system‘s power.
This series has been designed to maximise the availability of critical loads and to
ensure that your business is protected from variations in the power distribution line
voltage, frequency, electrical noise, cuts and micro-cuts. This is the primary goal
of the KESSUPS 92RT series.
4.3 UPS OPERATING MODES
Normal mode
The device supplies output voltage from the inverter, mains power present with
correct input voltage and frequency.
Battery mode
The device runs with mains voltage or frequency out of range or without AC
input power, either due to mains failure or absence of cable connection,
supplying output voltage from the batteries.
Bypass mode
No matter the device is running or not, it supplies output voltage directly from
the AC mains.
With the inverter running, this operating mode may occur due to an overload,
blockage or inverter fault. The actions for each incident will be as follows:
Reduce the load connected to the output, unblock the device by resetting it
(stop it and start it again) and if the fault remains, contact the KESS service.
With the inverter shut down, the output supplies the main power directly through
the static bypass of the device, provided that it has AC input power.

12 KESS Power Solutions GmbH / www.kess.at / [email protected]
Frequent converter mode (CF)
Operating mode of the UPS as a frequency converter. In this mode, the static
bypass is disabled by the condition of disparate input and output frequencies.
Even if the LCD monitor shows a messages, it does not mean that the inverter
is operational. It is switched on by pressing the ‘ON’ button on the control
panel, see chapter 7.
4.4 SPECIFIC FEATURES
• True online with double-conversion technology and output frequency
separate from the mains.
• Output power factor 1. Pure sine waveform, suitable for almost all kinds of
loads.
• Input power factor > 0.99 and high overall performance (between 0,89 and
0,91 for models up to 3 kVA models and > 0,93 for higher power ratings).
Greater energy savings and lower user installation costs (wiring) are achived,
as well as low distortion of the input current, which reduces pollution in the
power supply network.
• Great adaptability to the worst conditions of the mains. Wide input voltage,
frequency and waveform ranges, thus avoiding excessive dependence on
limited battery power.
• Possibility of fast and easy backup extension by adding modules in rack
format. Each battery module has two connectors for easy connection to the
device and other identical modules.
• N+X redundant parallel connection to increase reliability and exibility in
power models > 3 kVA, with a maximum of 3 devices in parallel.
• Selectable high-performance mode (ECO MODE) > 0,95 to 0,99 depending on
the model. Financial savings for the users are possible.
• It is possible to start the device without mains power supply or discharged
battery. Be careful with this aspect because the greater the batteries are
discharged, the more the backup will be reduced.
• Intelligent battery management technology is very useful for extending the
lifespan of the accumulators and optimising the recharge times.
• Standard communication options via the RS232 serial port or USB port.
• Digital input for Start/Stop of the device and ‘Error or fault’ digital output in
models with power ratings > 3 kVA.
• Remote emergency power off control (EPO).
• Control panel with LCD monitor available on all models and LED indicators on
devices with power ratings > 3 kVA.
• Availability of optional connectable cards to improve the communication
capabilities.
• The device can be installed as a tower or rack using the attached supplies. The
control panel can be rotated.

4.5 OPTIONAL SUPPLIES
Isolation transformator
The isolation transformer provides galvanic isolation in order to completely
isolate the output from the input and/or change neutral mode. The placement
of an electrostatic screen between the primary and secondary windings of the
transformer provides a high level of electrical noise attenuation.
The isolation transformer can be physically placed at the input or output of the
UPS depending on the technical conditions of the whole system (device supply
voltage and/or load voltage, characteristics or their type, etc.).
In parallel systems, it is not possible to operate with independent transformers
for each UPS. In contrary, it is necessary to have a single common element for
the total adequate power. In any event, it will always be supplied as a
peripheral component external to the device itself in a separate box.
External maintenance bypass
The purpose of this option is to electrically isolate the device from the mains
and the critical loads without cutting the power to the latter. In this way,
maintenance or repair operations on the device can be carried out without
interruptions to the power supply of the protected system, while preventing
unnecessary hazards for the technical personnel.
Communication card
The UPS features a slot at the rear for inserting one of the following
communication cards:
• Integration using an SNMP-Adapter: Large computer systems based on LANs
and WANs that integrate servers in different operating systems must provide
the system manager with ease of control and administration. This facility is
obtained through an SNMP adapter. While the connection betwenn UPS
and SNMP is internal, the connection of the SNMP is made through a RJ45-10
base connector.
• Relay interface card: The UPS has an optional interface for relaycards
that provides digital signals in the form of potential-free contacts, with a
maximum applicable voltage and current of 240 V AC or 30 V DC and 1A. This
communication port enables a dialogue between the device and other
devices through the relays supplied in the terminal block (arranged on the
same card), with a single common terminal for all of them. From the factory, all
contacts are „normally open“ and can be changed one by one, as explained
in the information concerning the optional supplies. Please contact our KESS
Service for further information.

14 KESS Power Solutions GmbH / www.kess.at / [email protected]
Extendible guide bars for rack mounting
An extendible guide bar is optional available for all models. These bars allow the
19“ rack installation for any KESSUPS 92RT-device and any battery module.

In this manual, references are made to the connection of terminals and switch
operations that are only available in some versions or devices with battery
modules. Ignore the described operations if your device does not feature them.
The thermal controls of these devices are carried out with forced air ventilation
from the front to the rear. The front surface and about 15 cm on the rear side
should be left free of obstructions to facilitate the free air circulation.
