5. Preparations before First Start-up

To ensure normal operation of UPS, please confirm the following before use:

A. Correct installation of input and output.

B. If supply terminals connect to the rated power. .

C. Confirm that UPS output does not short circuit and the load capacity does not exceed UPS capacity.

D. Confirm if computer or other instrument is turned off.

E. Confirm if battery voltage is normal.

F. It is not recommended to connect reactive load to the UPS output. Loads are normally powered by electric network directly.

6. UPS Start-up Sequence

After confirming all the above, please start the machine by following means:

A. Press the "ON/TEST" button on the UPS panel to start UPS, the "INV." indicator light will light up. After retardation time, the

"BYPASS" light goes out and the UPS is changed inverter power supply. By this time, the start-up is completed and the

equipment starts operation. Wait for about 20 seconds after normal no-load operation to turn on the computer or other

instrument. Start the load in the sequence of high-power to low power, first start the high-power equipment then in turns start

equipment with lower power.

B. Start computer or other equipment.

7. Daily Start-up and Shutdown

During daily operation, operate as per the following for start-up or shut down:

A. Press the "ON/TEST" button on the UPS panel to start UPS, after 10 seconds, turn on the computer or other instrument.

B. Normally, only when the UPS has been started and is working stably, can the loading equipment power switch be turned on. First

turn on high-power equipment, then the equipment with lower power. Some equipment has large start current (such as monitors of

some brands). When starting such equipment, overload protection (such as bypass operation) may occur. In this case, it's

recommended to start this type of equipment before other equipment.

Before shutdown, turn off the computer and other instrument first and perform no-load operation of UPS for 10 minutes. After the heat

in the equipment has been discharged, press the "OFF" button on the panel.

8. Maintenance Guide

Proper maintenance includes preventive maintenance and remedial maintenance, which is crucial to optimum operation of UPS and

can ensure relatively long service life of the equipment. Preventive maintenance includes some procedures that are frequently

performed. These procedures are used to prevent system failure as well as to obtain best operating efficiency. Remedial

maintenance includes searching for system malfunction to facilitate effective repair.

9. Safety Precaution In order to securely and successfully conduct system maintenance, relevant safety precautions must be observed and necessary

tools and testing equipment must be used, with the participation of qualified maintenance personnel. Pay attention to the following

safety operation rules:

A. Bear in mind that the equipment contains lethal voltage even if the system is not in operation.

B. Servicing should be performed by qualified service personnel with knowledge of the UPS and required precautions. Keep

unauthorized personnel away from the equipment.

10. When operating UPS, do not wear gold or silver jewelry such as ring or watch, etc.

11. Do not take the safety operation procedure for granted. If there is any doubt, consult personnel who are familiar with

the equipment. Be cautious that there is dangerous voltage in UPS. Before maintenance and adjustment, use voltmeter to check and ensure that the power is turned off and the equipment is under safe condition.
