Communication Port Explanation The UPS is equipped with EPO dry contacts input, true RS232 & USB Communication port as standard to provide communication with bundled UPS monitoring software for remote monitoring of UPS status via PC. There are 4 other optional interface cards available to meet various communication needs, i.e.
The Pin Assignments of the true RS232 port are illustrated as follows: Pin 3: RS232 Rx Pin 2: RS232 Tx Pin 5: Ground 3.4.2 USB Port Descriptions The USB communication protocol definition as below: Complies with USB version 1.0, 1.5Mbps Complies with USB HID Version 1.0.
Installation and Operation Read the Safety Instruction guide (page 2 to 3) before installing the UPS Unpacking Inspect the UPS upon receipt. Staco has designed robust packaging for your product. However, accidents and damage may occur during shipment. Notify the forwarder and dealer if there is damage. The packaging is recyclable;...
Selecting Installation Position The UPS is heavy. Select a location sturdy enough to handle the UPS weight. To ensure proper operation and long operating life, always position the UPS according to the following requirement: 1. Keep minimum 20cm (8 inches) distance clearance from the rear panel of the UPS to avoid any obstructions.
Operation 4.4.1 Start Up In Normal Mode (1) Make sure the voltage of Utility matches with the input voltage window of the UPS. (2) Connect the UPS to the wall Receptacle of the Utility. After a short delay the UPS will automatically start. LED light up to indicate the Utility and the Bypass are normal.

(3) The UPS is on Bypass Mode now and will proceed to self-test automatically. If there is no abnormal message then the pre-start-up of the UPS was successful and the charger begins to charge the batteries. ‟for approx. 3 seconds, until the unit (4) Press the UPS On Switch„...
(6) The start-up sequence of the UPS is complete as illustrated as drawing E. Make sure the UPS is plugged onto the wall receptacle for at least 8 hours to ensure the batteries are fully charged. To turn off the UPS press and hold the Off switch until the alarm beeps twice, then release the switch.
4.4.1.2 Check Measured Values & Figures detected by UPS (1) If you would like to check the measured values & messages, please use scroll up and scroll down key pads. When you use the scroll down key pad, the LCD display will change in sequence from Drawing E(Input Voltage) ...

UPS Working Principle 5.1. UPS System Block Diagram (fig 5.1) Figure 5.1 above illustrates the True On-Line Double Conversion architecture of the UPS system. The major modules consist of: 1) An AC to DC power converter (Rectifier) with PFC control circuit 2) A DC to AC power high frequency inverter 3) An Intelligent Battery Charger 4) A bank of stationary maintenance-free batteries...
LEDs Display Utility Conditions UPS Operating Modes indications Rectifier convert AC to DC, battery charging, Inverter convert DC to AC LEDs Utility Normal and supply to loads with clean & stable remain illuminated power. Rectifier and charger stop operating, Battery discharge via DC~DC boost Utility Abnormal LED off, circuit and supply to Inverter.
When Utility is Abnormal/Absent The working principle of the UPS under Utility abnormal condition is illustrated as follows: Fig 5.3 1. When Utility is abnormal, the UPS will direct the battery energy automatically to the Inverter without delay, and turn off the charger and AC/DC converter. The inverter converts the DC to AC to supply energy to the output connected load without interruption.
Overload Condition The working principle of the UPS when overloading is illustrated as follows: (1) Generally, modern electronics & IT equipment generate an inrush current when switching on. The amount of inrush current varies from equipment to equipment, some can be as high as 6 times its rated capacity while others produce negligible inrush.
2. The UPS Bypass loop is also equipped with overload protection. Its overload capacity is illustrated by the graph & table below. Inverter Failure Output Load short circuit when being supplied from inverter If the output load is shorted while being supplied by the Inverter, the UPS will shutdown the Inverter automatically.
Inverter/Internal Over temperature If the UPS experiences internal over-temperature while the Utility is normal, it will switch to bypass loop. The UPS will switch back to inverter mode when the over- temperature situation is eliminated. If over temperature occurs when Utility is abnormal, it will beep continuously and the Fault LED will light up.
Maintenance Guide Trouble Shooting When the UPS becomes faulty or malfunctions during operation, you may check the fault lists below for possible solutions. Should the problem persist, please contact Staco for assistance. Error Codes and Their Descriptions Code Descriptions Er05 Battery weak or faulty Er06 Output short-circuited...
