I. GENERAL DESCRIPTION
1.1 Introduction
TESCOM DS300T-HF1 Series Uninterruptible Power Supplies are double-conversion;
on-line UPS’s manufactured with the latest IGBT and PWM technology, to produce an
uninterruptible, fully DSP (Digital Signal Processor) controlled pure sine wave output to
critical loads.
TESCOM DS300T-HF1 Series units are 3-phase in/3-phase out devices, and they are
installed between a three phase critical load, and a 3-phase+N mains supply
The advantages of using DS300T-HF1 UPS:
•Power blackout protection:
If the mains power fails, the UPS continues to supply the critical load using the
energy stored in its batteries, keeping the load immune from power disturbances.
•Increased power quality:
The UPS has its own internal voltage and frequency regulating software, which
ensures that, its output to the critical load is maintained within close tolerances, independent
of voltage and frequency variations on the mains power lines.
•Fully digital control by three DSP controller for each UPS:
The UPS is controlled by 3 independent DSP chips which are communicating each
other continuously. Rectifier, Inverter and User Interface modules have separate DSP’s to
achieve the highest performance. Each DSP module has many parameters to control and
monitor the system to have the best electrical power output and to help diagnostic.
•Increased noise rejection:
By rectifying the input AC power to DC power and then converting it back to AC
(Double-Conversion) any electrical noise present on the input mains supply line is effectively
isolated from the UPS output. Therefore the critical load is supplied with only clean and
uninterrupted AC power.

1.2.1 DESCRIPTION OF BLOCKS
RECTIFIER: In DS300T-HF1 Series UPSs, a DSP controlled IGBT rectifier with PWM technique is used to
increase input power factor (PFC) and to decrease input current harmonics (THDI).
The IGBT rectifier accepts 3-phase AC input and produces a dual polarity DC voltage for both supplying
the inverter and charging the batteries.
BATTERIES: Batteries are used as reserve DC power supply for the Inverter in case of mains failure. In
DS300T-HF1 Series, batteries are connected in series with a center-tap output to obtain a dual polarity DC
supply.
Batteries are discharged by the inverter during mains failure. The discharged batteries are re-charged by
the IGBT Rectifier on a constant voltage / current limiting basis, if AC mains power is available.
INVERTER: It is manufactured by using the latest IGBT and DSP (Digital Signal Processing) technologies,
and Pulse Width Modulation (PWM) technique. The Inverter converts the DC BUS voltage supplied by the
IGBT Rectifier and / or the batteries into a well regulated, fully digital controlled 3-phase AC voltage with
fixed voltage and frequency.
The output of the inverter is used to supply the critical loads connected to the UPS output.
STATIC TRANSFER SWITCH (STATIC BYPASS): This is an electronically controlled transfer switch,
which enables the critical load to be connected either to inverter output or to by-pass power source. During
normal operation, the load is supplied by the inverter output, but in case of an overload or a UPS failure it is
automatically transferred to the bypass source without any interruption.
MAINTENANCE BYPASS SWITCH (MBS): This is a manually controlled mechanical switch, which is used
to supply the critical load, using the bypass source, when the UPS is shut down for maintenance or
troubleshooting purposes.
The load is unprotected against mains supply disturbances and black-outs when it is connected to either
static or maintenance bypass supply.
1.2.2. OPERATING CONDITIONS OF UPS
UPS may be in one of the following operating conditions:
A. Normal Operation (If Mains supply is available):
All fuses and power switches are closed (except the Maintenance Bypass Switch), and the load is supplied
by the Inverter Output. During normal operation, the Rectifier supplies DC power to the Inverter and
charges the Batteries at the same time.
B. Battery Operation :
The Batteries are connected to the Rectifier output. In case of a mains failure (mains power outage or AC
input voltage out of tolerance), the Rectifier stops operating and the DC voltage necessary for the inverter
operation is supplied by the batteries. Therefore the AC voltage output supplying the critical load is not
interrupted, until the batteries are fully discharged. At the end of the discharging time the inverter is turned
off and it start again automatically, together with the rectifier, when the mains power is restored, and the
UPS returns o normal operation. For UPS with a split bypass source, at the end of discharging time, static
transfer switch transfers the load to the split bypass source without interruption if the split bypass source is
available and in acceptable tolerances about voltage and frequency, as still the rectifier input is not
available.
The Rectifier is also turned off and inverter operates on batteries during automatic or manual battery test
procedure.
C. By-Pass Operation :
If the Inverter output is overloaded or in case of a problem in the UPS, the static switch transfers the load to
the bypass supply without any interruption, provided that the bypass supply is available and within the
tolerated limits regarding voltage and frequency. At the end of the overloading period, if the fault condition
is restored, static switch transfers the critical load again to the inverter output. Note that, during operation
from the bypass supply, the critical load may be effected by any possible disturbances or power failure in
the bypass supply.

2.4 Connecting the UPS Power Cables
WARNING!!! A separate power line should be used to supply the UPS AC input. Never use the
same line to supply another electrical device. Do not use any additional cable to
increase the length of the UPS’s input cable. It is advised to use an MCCB suitable
for the input current on the UPS’s input line.
The connection of the electrical panel should be supplied by a grounded outlet. Otherwise,
the UPS and the load connected to the output will be left ungrounded. The
grounding system must be checked, and must be strengthen if required. Potential
difference between ground and neutral must be less than 3V AC.
Descriptions of the UPS input output cable connection terminals are shown in figure 2.1
Recommended input line cable and fuse ratings are given in the table below.
NOTES: The neutral conductor should be sized for 1,5 times the output/bypass phase current. These
recommendations are for guideline purposes only and are superceded by local regulations
and codes of practice.
2.5 Safety Earth
The safety earth cable must be connected to the earth BUS BAR and bonded to each cabinet in
the system and also the earthing and neutral bonding arrangements must be in accordance with
the local laws.
ATTENTION!!! Failure to follow adequate earthing procedures can result in electric shock hazard to
personnel, or the risk of fire.
2.6 Cable connection procedure
WARNING!!! All connections of the UPS must be done by qualified service personnel

2.7 Battery Installation
WARNING!!! Be careful while connecting batteries.
ATTENTION!!! Open the battery switch/fuse before making any connection on the batteries.
The batteries associated with the UPS equipment are usually contained in a purpose-built battery cabinet.
Where battery racks are used, they should be sited and assembled in accordance with the battery
manufacturer’s recommendations. In general, batteries require a well-ventilated, clean and dry environment
at reasonable temperatures to obtain efficient battery operation.
In general a minimum space of 10 mm must be left on all vertical sides of the battery block. A minimum
clearance of 20 mm should be allowed between the cell surface and any walls. All metal racks and cabinets
must be earthed.
2 Unpack each battery and check its terminal voltage with a suitable load. Any battery with terminal
voltage less than 10,5V must be charged before installation.
3 Please check the battery connecting hardware and documents. (cables, trays, connection diagrams)
4 Please locate suitable number of batteries on each rack, according to the battery installation and
connection diagram given with the unit.
5 Start locating the batteries from top to the bottom on the racks.
6 Be careful about the connection between the racks and polarities.
7 After interconnecting the batteries, connect “+”, “0” and “-“ leads of the batteries to the battery input
terminals on the UPS. Be careful to connect the batteries correctly and do not turn on (S5) before
checking all connections and before starting the UPS. In DS300T-HF1 Series UPS, 40 blocks of
batteries are connected in series, in such a way that they form two strings of batteries with opposite
polarity; with a center tap connection to the NEUTRAL (N1-N2) internally.
NOTE THAT SEPARATE CABLES FROM EACH BATTERY GROUP SHOULD BE CONNECTED TO K2
TERMINALS TO FORM THE MIDPOINT CONNECTION.
WARNING!!! NEVER TURN ON S5 (BATTERY FUSE) WITHOUT CENTER POINT CONNECTION TO K2.
