3. INTRODUCTION
The battery backup system provides constant and reliable backup power to outdoor equipment. It consists of
Uninterruptible Power Supply (UPS) System and optional Power Transfer Switch (PTS) that provide backup
power when the line is unqualified. These components should be mounted inside an enclosure to provide
protection from most weather conditions.
3.1 System Architecture
Figure 1: Battery Backup System Block Diagram

3.2 UPS Module
The UPS module provides utility power to load when line is qualified. And an automatic voltage regulator (AVR)
is embedded to provide stable power to the load. It will instantly switch to emergency backup power during
utility power failure or interruption. The front panel view is shown as below.
Figure 2: Front Panel of UPS
AC Input Terminal Block
This terminal block is the UPS AC line power input.
AC Input Breaker
This circuit breaker is an on/off switch for the line power into the UPS that also provides input protection. It
must be switched on for proper UPS operation.
AC Output Terminal Block
This terminal block is the UPS AC power output.
AC Output Breaker
This circuit breaker is a resettable protective thermal circuit breaker to protect UPS output from overload and
short circuits.
Input Contact
To activate a programmable alarm by shorting this input contact.
Dry Contact
Six sets of dry contacts will energize when programmable event occurs.
Internal Fan
It’s to cool down inside temperature of the UPS. The fan is flexibly replaced for maintenance.
GND
This connector is permanent ground of the UPS.
Battery Connector
The battery connector is to connect external batteries.
Mounting Bracket & Handle
This part is for unit mounting on the size of 19’’ cabinet and for people moving unit conveniently.
Battery Temperature Connector
This is used to monitor battery temperature. The temperature probe connector must be plugged in UPS for
normal operation. The other end should be firmly attached to the terminal of the battery.

4
External FAN Connector
To provide DC Power (48Vdc, 3 Amp Max) to an optional 48Vdc fan.
PTS Control Connector
This connector provides power to control the PTS unit.
Battery Breaker
This over-current protection is used as an on/off switch for the battery power. It must be switched on for proper
UPS operation.
Battery Voltage Test Points
The test points allow you to measure battery voltage. They accept 2 mm diameter test probe tips. The battery
circuit breaker must be turned on before measuring voltage.
CAUTION: The battery voltage test points are NEVER be used as a power outlet.
Function Keys
These buttons are used to operate and control the LCD panel.
LCD Display Panel
It shows the UPS information in four-line texts.
Indicator LEDs
Three LEDs show the information of output status, alarm and fault.
USB Connector
This is used to connect the UPS to the computer for remote control and monitoring.
RS232 Connector
A straight-through DB-9 to DB-9 connector cable can be connected in. It is used to connect the UPS to the
computer for remote control and monitoring.
Intelligent Slot (optional)
This optional slot is for SNMP card insertion to communicate with UPS. The UPS can be monitored and controlled
via a web browser or with SNMP protocols.
3.3 PTS Module (Optional)
The Power Transfer Switch (PTS) shown below allows the UPS to be removed for service, replacement or
maintenance without interrupting power to the outdoor equipment.
Figure 3: Front Panel of PTS with terminal block
AC Input Terminal Block
The line input power is connected to the terminal block marked with “AC IN”.
AC Output Terminal Block
The output power is connected to the terminal block marked with “AC OUT”.

5
Switch
UPS or bypass output can be selected by this switch.
AC Output Breaker
This circuit breaker marked with “OUTPUT’’ is a resettable protective thermal circuit breaker to protect the
output from overloads and short circuits.
AC Input Breaker
This circuit breaker marked with “UPS INPUT’’ provides input power protection for the UPS.
AC Output Receptacles
These receptacles are ready to use for optional battery heating pads or a PC for maintenance.
UPS Input Connector
This “UPS IN” power cord is connected to AC input connector or terminal blocks on UPS.
UPS Output Connector
This “UPS OUT” power cord is connected to the AC output connector or terminal blocks on UPS.
PTS Control Wiring
The Black and Red PTS control wires are used to connect to PTS control connector on UPS.
