3. INTRODUCTION
The battery backup system provides constant and reliable backup power to critical electronics. It consists of the Uninter-
ruptible Power Supply (UPS) System and optional Manual Bypass Switch (AC-UPS-BP) that provides backup power when
the line is unqualified. These components should be mounted inside an enclosure to provide protection from most weather
conditions. A separate battery string is required.

3.2 UPS Module
The UPS module provides utility power to the load when the line is qualified. An automatic voltage regulator (AVR) is
embedded to provide stable power to the load and instantly switches to emergency backup power during utility power
failure or interruption. The front panel view is shown 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, see section 5.5.9.
Dry Contact: Six sets of dry contacts energize when a programmable event occurs, see section 5.5.9.
Internal Fan: The fan is to cool down the inside temperature of the UPS and is easily replaced for maintenance.
GND: This connector is the permanent ground of the UPS.
Battery Connector: The battery connector is to connect external batteries.
Mounting Bracket & Handle: The Rugged UPS Series is for mounting in a 19’’ cabinet. For convenience, handles are
provided for people frequently moving the unit. Mounting hardware includes (quantity 8): M4 x 3mm Flat Head, Phillips,
S.S.
Battery Temperature Connector: This probe monitors battery temperature. The temperature probe connector must be
plugged into the UPS for normal operation. The other end should be firmly attached to the terminal of the battery.
External FAN Connector: To provide DC Power (48V DC, 3 Amp Max) to an optional cabinet 48V DC fan.
MBS Control Connector: This connector provides power to control the MBS unit.
Battery Breaker: This over-current protection acts as an ON/OFF switch for the battery power. It needs to be 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 ON before measuring voltage. CAUTION: The battery voltage test points
are NEVER to be used as a power outlet.
Function Keys: These buttons operate and control the LCD panel.

AC Output Terminal Block: The output power connects to the terminal block marked with “AC OUT”.
Switch: This switch selects UPS or bypass output.
AC Output Breaker: This circuit breaker labeled “OUTPUT’’ is a resettable protective thermal circuit breaker to protect
the output from overloads and short circuits.
AC Input Breaker: This circuit breaker labeled “UPS INPUT’’ provides input power protection for the UPS.
AC Output Receptacles: These receptacles are for optional battery heating pads or a PC for maintenance.
UPS Input Connector: This “UPS IN” power cord connects to AC input connector or terminal blocks on UPS.
UPS Output Connector: This “UPS OUT” power cord connects to the AC output connector or terminal blocks on UPS.
MBS Control Wiring: The Black and Red MBS control wires connect to the MBS control connector on the UPS.

5. OPERATION
To power up the UPS, ensure the switch on MBS is in “UPS Mode” position. Before commissioning, make sure batteries are
fully charged and line power is qualified.
5.1 Switch on UPS in Line Mode
1. Switch the battery circuit breaker ON. All LEDs will illuminate and the LCD will display, the Startup page, and fan will
turn on.
2. Switch the AC input breaker ON. After line power is qualified, the LCD will display normal, buck or boost according to
line voltage range and line threshold setting.
Note: The AVR function default setting is disabled. You may activate it via the LCD panel or USB/RS232/SNMP communi-
cation.
5.2 Switch the UPS from Line Mode to Battery Mode
The UPS will operate in battery mode, if the input circuit breaker is manually switched OFF. The LCD will display Battery
and the output LED will flash and alarm LED will illuminate to show the UPS is running on backup battery power.
5.3 Switch from Battery Mode to Line Mode
After switching input circuit breaker ON and if the line input is qualified, the UPS will transfer to line mode with the output
LED “ON” to show UPS is running from utility power.
Note: If the UPS keeps switching between inverter and line mode because of a noisy line, the setting of “UPS Sense type”
should be changed from Normal or UPS to Generator.
5.4 Switch Off Procedure
For any reason you need to switch off UPS, please follow below procedure.
1. Switch the output circuit breaker OFF.
2. Switch the input circuit breaker OFF.
3. Switch the battery circuit breaker OFF. The output LEDs and the LCD display will shut off.
5.5 Operation the Control Panel
The control panel includes four-line LCD display, three LED indicators, three function keys, input contacts and six sets of
dry contacts. The UPS can be rotated 90 degree for vertical installation.
5.5.1 LED Indicator 5.5.2 Function Keys
LED Indicator Messages
Output Green Solid On Output is available in line mode
Flashing Output is available in battery mode
Off Output is not available
Alarm Yellow Solid On Alarms occur in the system, indicat-
ing a condition not serious enough to
