1. IMPORTANT SAFETY INSTRUCTIONS

 This manual contains important instructions for the unit that should be followed during

installation and maintenance of the UPS and batteries.

 Install the on line UPS in a well ventilated area, away from flammable liquids and gases. Do

not let the unit come in contact with water.

 External slits and openings in the cabinet are provided for ventilation. To ensure reliable

operation of the product and to protect from overheating these openings must not be blocked or covered. Objects must never be inserted into ventilation holes or openings.

 Do not stand beverage containers on the unit.  This UPS was designed to power all modern computer loads and associated peripheral

devices, such as monitors, modems, cartidge tape drives, external floppy drives etc.. Do not use it for pure inductive or capacitive loads. It is not rated to power life support equipment.

 All recorded media, such as diskettes, tapes and cartridges, should be kept a minimum of

60cm from the UPS. Otherwise, the magnetic field created by operation of the UPS may erase data on those devices.

 All repairs or installation should be performed by qualfied service personnel. The UPS

contains voltages which are potentially hazardous. The output receptacles may be alive even when the UPS is not connected to the mains.

 Risk of a possible electrocution is possible when the battery is connected to the UPS.

Therefore, do not forget to disconnect the batteries before any service is to be done on the UPS. To disconnect, remove the battery fuse holder which is located at the rear panel of the UPS.

 Isolate Uninterruptible Power Supply (UPS) before working on the circuit. A readily accessible

disconnect device shall be incorporated in the fixed wiring.

 HIGH LEAKAGE CURRENT – Earth connection essential before connecting power source.  Federal Communications Commission Interference Statement

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC Caution: To assure continued compliance, (example-use only shielded interface cables when connecting to computer or peripheral devices). Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.

 ATTENTION, hazardous through electrical shock. Also with disconnection of this unit from the

mains, hazardous voltage still may be accessible through supply from the batteries. The battery supply should be therefore disconnected in the plus and minus pole of the batteries when maintenance or service work inside the UPS is necessary.

 Do not dispose of the batteries in a fire, the batteries may explode.

 Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin

and eyes. It may be toxic.

 A battery can present a risk of electric shock and chemical hazard. The following precaution

should be observed when working on batteries.

* Remove watches, rings or other metal objects. * Use only tools with insulated handles.

- The compliance with the following standards provides the conformity:

- EN 62040-1-1

- EN 62040-2 CLASS A

- IEEE-C62.41 Category B

- IEC 61000-2-2

2. INTRODUCTION

2-1 FUNCTIONS AND FEATURES

 A True ON LINE design. The UPS insures the critical power protection for your

mission-critical equipment at all times.

 Wide input range of power supply that reduces discharge rate of battery.  A smart charger design for auto equalizing charge to shorten charging time.  Equipped with RS232 port and Dry-contact interface, using the power management

software “UPSentry Smart 2000” allows near-end and far-end UPS monitoring management.

 Automatic detection of 50/60Hz field input frequency  With excellent performance. Input current using active input power factor correction

and a high-frequency inverter with pulse width modulation.

 Optional isolated output transformer: Provides isolation and multiple output voltage.  Start-on-battery capability for powering up the UPS even if utility power is not

available.

 Optional SNMP interface card is an optional accessory for network communication.  Implementing diagnostic test and LCD message display by using microprocessor

technology can provide detailed information on operation status.

 Manual and static bypass switch forms. Allowance for switching to the main power

supply.

 Static bypass supply circuit incorporates functions such as surge suppression and

EMI filter.

 Remote emergency power off (REPO): Emergency shutdown control through the

remote emergency power-off (REPO) port.

 Auto recovery function of inverter:

 When the AC pow er is restored after a low battery shutdown, the UPS inverter will

automatically restart.

 Automatic transfer to inverter output from static bypass after overload condition is

cleared.

 Alarm cancel facility to switch off the audible alarm and indicative lights still lit in the

event of long BACK-UP periods.

 External battery cabinet can be used for extending operation time of battery mode.  Operation of “ECONOMIC Mode” (Optional): When input voltage is within the range of

rating voltage (±10%), the UPS is working in the bypass mode for higher efficiency. Otherwise the UPS will be switched to inverter mode.

 Auto detection for voltage in bypass mode: The protection range is +15%~ - 20%.

When the bypass voltage is beyond protection range, the UPS will not supply output power to the load.

 Auto detection and display for normal operation of fan.
