1.2.1 Description of Blocks RECTIFIER: In DS300H 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 produ produces a dual polarity DC voltage for both supplying the inverter and charging the batteries.

IV. PARALLEL OPERATION 1 Introduction Two (or more) identical DS300H series UPSs can be interconnected for parallel operation. The main purposes for parallel use of DS300H series UPSs are: -Redundancy for Increased Reliability -Power Increase Although recent UPS designs are perfect and have high MTBF figures, a second (or more) UPS can be used in parallel with the first one, for supplying the critical load in case of any possible failure of the first UPS.
The AC inputs of all UPSs in the parallel system are connected to the same mains, and all the AC outputs are connected to each other. Each UPS has its own battery group. The critical load is connected to the common output of the parallel system. There are also some signal cable connections between the UPS units necessary for parallel operation, and will be described later.

ATTENTION!!! The cables from input distrubution panel to the UPS by-pass input must be of the same size and length for proper bypass load sharing. The cables from each UPS output to the load distribution panel must be of the same size and length for proper load sharing during parallel operation.

V. PARALLEL OPERATING INSTRUCTIONS 5.1 INTRODUCTION After all the electrical connections of UPS have been made and while all the circuit breakers and switchtes of the device are turned OFF (at “0” position); 1. Check the polarities of battery connections: : + V (nominal voltage +360V, float charge voltage +405V) K2-K2 : 0 V (common terminal for ‘’+’’...
5.2.3 Switching the UPS from a Normal Operation to Maintenance Bypass Condition 1. Enter COMMANDS menu by using UP and DOWN buttons on front panel during normal operation. Select ENTER<BYPASS> command by using again the UP and DOWN buttons and pres ENTER button.
VI. NORMAL OPERATING INSTRUCTIONS 6.1 OPERATING UPS IN ONLINE MODE 6.1.1 Starting UPS from a completely shut down position: Turn ON S1 (AC Input) switch (switch to ‘’1’’ position) Turn ON S2 (Bypass) switch (switch to ‘’1’’ position) Turn ON S4 (AC Output) switch (switch to ‘’1’’ position) ATTENTION!!! BYPASS VOLTAGE WILL BE CONNECTED TO THE OUTPUT TERMINALS OF UPS WHEN THE ON/OFF SWITCH (S7) IS SWITCHED ON !
6.1.4 Switching the UPS from a Maintenance Bypass Condition to Normal Operation Turn on S1 (AC Input) switch (to ‘’1’’ position). Turn on S2 (Bypass) switch (to ‘’1’’ position). Turn on S4 (AC Output) switch (to ‘’1’’ position). Turn on S7 (On/Off) switch (to ‘’1’’ position). LCD panel activates, and main menu will appear at the display.
VII. MAINTENANCE ATTENTION !!! There are no parts inside the UPS or battery group that needs service or maintenance work that should be done by user. Therefore DO NOT OPEN THE COVER OF UPS. Never touch on any terminal of battery group. There is risk of electric shock inside the UPS even when it is completely turned off (because of energy storage components).
Take notes if possible when you are examining the UPS. Compare the notes with previous ones and try to determine if there is a change or not. If there is a difference between the previous notes and the new ones, search for and record any new load added to UPS output between two records and the magnitude, place and type of the new load, if possible.
VIII. FAULTS AND TROUBLESHOOTING 8.1 General Procedure For Fault Checking And Troubleshooting UPS contains complicated electronic control circuits. In order to locate any fault occurring circuits, an advanced knowledge about the circuitry and its operation principles must be known. The aim of this section is to give the knowledge required at the first intervention.
Using one of above communication options is satisfactory for remote monitoring and control in most of the systems. But in some systems may use 2 or 3 of above options at the same time. In this case accessories group produced by Tescom may help to make appropriate solutions. 9.1 Using Serial Port Two serial communication port is included on DS300H Series UPS cabinet (com1 and com2).
9.3 Modem Connection A DS300H Series UPS can be controlled through a normal telephone line by means of a remote operator connected through a PC with modem device, who performs a phone call to the UPS connected number. So the operator can see all parameters and control the UPS (if permitted from OPTIONS MENU). 9.3.1 Hardware Configuration All requirements for modem connection are as follows: •...
9.3.4 Modem – UPS Connection Cable Connection of Smart Modem device to UPS is made with standard modem cable and it’s supplied as standard accessory for smart modem. This cable is required if an external modem will be used, and not necessary for internal modems.
EFFICIENT USAGE OF UPS IN TERMS OF ENERGY CONSUMPTION Products should be used according to the conditions and procedures defined in the manual. When this is made the most efficient usage of the product is guaranteed. Energy efficiency means, decreasing consumed energy amount to the minimum level possible in every step of living activities, without a decrease in quality or amount of produced work or product, and keeping this principle permanent.
