wiring socket outlet), components inside the UPS system are still connected
to the battery and are still electrically live and dangerous. Before carrying out
any kind of servicing and/or maintenance, disconnect the batteries and
verify that no current is present.
2. Only persons adequately familiar with batteries and with the required
precautionary measures may exchange batteries and supervise operations.
Unauthorized persons must be kept well away from the batteries.
3. Batteries may cause electric shock and have a high short-circuit current.
Please take the precautionary measures specified below and any other
measures necessary when working with batteries:
- remove wristwatches, rings and other metal objects
- use only tools with insulated grips and handles.
4. When changing batteries, install the same number and same type of
batteries.
5. Do not attempt to dispose of batteries by burning them. This could cause
battery explosion.
6. Do not open or destroy batteries. Escaping electrolyte can cause injury to
the skin and eyes.

7. OPERATION MODES OF THE UPS
7.1 UPS System Block Diagram
7.2 Normal Operation
There are two main loops when AC utility is normal: the AC loop and the
battery charging loop. The AC output power comes from AC utility input and
passes through AC/DC rectifier, DC/AC inverter and static switch to support
power to load. The battery charging voltage comes from AC utility input and
converted by AC/DC charger to support battery-charging power.
25
7.3 AC Utility Failure
The AC output comes from battery, passing through DC/AC inverter and
static switch within the battery backup time.
7.4 Bypass Enable
Under the following conditions, the bypass will be enabled:
1.Overload.
2.Inverter failure.
3.Over-temperature
4.DC BUS fail

26
8. COMPUTER INTERFACE
8.1 communication interface
The communication interface (DB9 port) on the back of the UPS may be
connected to a host computer. The port provides two different modes for
communicating with the computer like below.
1. Supply dry contact function (like RUPS of Megatec Company)
The port simulates relays closing to communicate with the computer. Its
major functions are as follows.
(1) To broadcast a warning when power fails.
(2) To close any open files before the battery exhausted out.
(3) To turn off the UPS.
2. Supply RS-232 for monitoring software (like RUPSII or UPSilon 2000 of
Megatec Company)
The UPS communicates with the computer by sending out RS-232 data
streams to one of the serial ports. By this method the user is able to monitor
the following parameters.
Input Voltage Indicates the present input voltage to the UPS
system when AC power is present.
Output Voltage Indicates the present output voltage of the UPS.
AC Frequency Indicates the actual output frequency of the UPS.
Battery Voltage Indicates the present DC voltage of the UPS
battery.
Temperature Indicates the actual temperature inside the UPS.
