SAFETY INSTRUCTION – CAUTION

1 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This manual contains important

instructions that should be followed during installation and maintenance of
the UPS and batteries.

WARNING: Do not attempt to perform repair or service with this UPS.
This UPS contains high voltage which could cause electrical shock
even when the unit is disconnected from the mains outlet; the
dangerous voltage may still be present through the battery. All
maintenance and battery replacement should be performed by
qualified service personnel only.

1. This UPS should be placed indoors with adequate airflow and free of
contamination. To install or operate it in a clean and indoor environment,
free from moisture, flammable liquids, and direct sunlight. Ambient
temperature range must be 0°C to 40°C (32°F to 104°F).

2. This UPS is designed for Commercial/Industrial use only. It is not intended
for use with life support application and other designated “life-critical”
devices.

3. Do not remove the input power cord when this UPS is turned on. Remove
the safety ground from this UPS and the equipment connected to the UPS.

4. Turn off this UPS and disconnect input power cord before battery

replacement.

5. Battery contains high short-circuit current. Replacing or servicing the

battery should be performed and supervised by qualified service personnel
who are knowledgeable of batteries and requires precautions.

 Remove watches and jewelries
 Use tools with insulated handles
 Wear rubber gloves and boots.
 Do not lay tools or metal parts on top of batteries.
 Disconnect charging source prior to connecting or disconnecting

battery terminals.

6. When replacing the batteries, use the appropriate replacement battery kits,

same number and type of battery are MUST.

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

and eyes that may be toxic.

8. Do not dispose of battery in a fire. Battery may explode. Proper disposal of

battery is required. Please refer to your local laws and regulations for
disposal requirements.

9. This UPS contains high voltages which may cause the risk of electric shock.

Do not remove cover. There are no user replaceable parts inside this UPS.
Please contact your local dealer or distributor for service.

10. This pluggable type equipment with battery already installed by the

supplier is operator installable and may be operated by laymen.

11. During the installation of this equipment it should be assured that the sum

of the leakage currents of the UPS and the connected loads does not
exceed 3.5mA.

12. Attention, hazardous through electric shock. Also with disconnection of

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

13. The wall outlet must be within 2 meters of the equipment and accessible

to the operator.

2. INSTALLATION

2.1 Inspecting the Equipment

If any equipment has been damaged during the shipping process, keep the
shipping cartons and packing materials for the carrier or place of purchase
and file a claim for shipping damage. If you discover damage after

computer to the USB port or UPS communication port using the
supplied cable (see page 16).

2. On 230V models (factory-set default), plug the detachable power cord

into the input connector on the UPS rear panel.

3. Plug the UPS power cord into a power outlet.

4. Plug the equipment to be protected into the UPS output receptacles.

DO NOT protect laser printers with the UPS because of the
exceptionally high power requirements of the heating elements.

5. Press down the button, then the indicator illuminates

indicating that power is available from the UPS output receptacles.
If the alarm beeps or a UPS fault indicator stays on, see page 25-26.
