1. Overview
1-1 Introduction

The PS family of UPS (Uninterruptible Power Supply), is a line interactive device with
features conceived to provide an excellent protection to computers (PC), networks,
workstations and small capacity internet devices.

The PS family has an Automatic Voltage Regulator (AVR) that allows to operate in stable
conditions under varations of the main power, without the need to get into battery or
backed up mode. This features results in in extended battery life.

The family uses a RISC (Reduced Instruction Set Computer), that provides greater
operational flexibility: 1) “Delayed turn on”. During the turn on process the microprocessor
analizes the main power in order to ensure that it is in adequate conditions for the unit to
operate. 2) Green Power function. 3) “Overload Detection” and desactivation of the load if
the overload persists during a predetermined time. Additionally, the PS family has surge
protection, nosie filtering and fax/modem protection.

2. INSTALLATION AND OPERATION
2-1. Installation

The following steps explain how to install the UPS to your PC.
Step 1. Assure AC power source output voltage is in the UPS
Requires voltage range specified on the rear panel.
Step 2. Plug the UPS power cord into a wall outlet or other
Power source.
Step 3. Plug the personal computer (PC) into the UPS output.
Step 4. Start the UPS by pressing the ON/OFF button for 4 seconds.
After the UPS turns on, it conducts a self-test and enters
Normal AC power mode. The AC power green LED indicator
illuminates indicating that power is available from the rear

receptacles.
Step 5. Shutdown the UPS by pressing ON/OFF button for 6 seconds
untill Red LED indicator illuminate.

2-2. OPERATION

2-2-1. Turning the UPS ON
Press the power ON/OFF on the front panel. After the UPS green
LED is turned on. It conducts a self-test and enters normal mode.
2-2-2. Starting the UPS on battery
To turn on the UPS without using AC power, press ON/OFF button

and Hold for 6 seconds to conserve battery power

(The UPS does not conduct Self-test when UPS start on battery).
2-2-3. Turning The UPS OFF
Press the power ON/OFF on the front panel when UPS power off.
