7.. UPS Start Up
a Connect the UPS to the utility power 220V/50Hz. Yellow LED will lights ON to indicate charge is normal.
Push the Main Switcher on the front panel to start the UPS. Green LED lights ON to indicate utility power is normal. The
start-up procedure is completed and the loads are supplied by the UPS.
b To start “cold start” procedure press the Main Switcher button on the front panel. The UPS starts to operate.
Note:This UPS has the built in function energy saving (Green Mode). In battery mode without load or loading less
than 20 watt of the UPS will be shut down in 1 minute.
7.. Turn Off the UPS
Press the Main Switch button again.
7.4. Battery Charging
The UPS purchases with charge batteries. Nevertheless batteries can lose some charge during transportation or
storage. That is why please charge the batteries during 8 hours after you switched on the UPS.
7.5. Connecting equipment to the UPS
To be sure the UPS will protect your equipment and provide back up time you have to know total capacity of the connected
equipment. Total load have to be less or equal of the UPS nominal capacity. If the load should be greater the UPS will
make alarm sound and red LED will light ON.
NOTE
To provide long term UPS using calculate total load capacity correctly and connect the load accordingly with
maximum available capacity of the UPS
Calculation of the capacity
Рl
>
0,7 * 0,8* Рups
Рl — active load in Watts.
0,7 — coefficient between active and full capacity.
0,8 — coefficient of the used capacity .
Рups — full UPS capacity in VA as a part of the UPS name. (For example for Pro+700 full capacity is 700VA etc. )
We recommend to use coefficient of the used capacity equal 0,8 for greater reliability. For critical equipment use 0,7-
0,8 range. For non critical equipment use 0,9-1,0 range.
7.6 Overloading and short circuit
If total load capacity is greater than UPS capacity fuse can disconnect the load. UPS will come to the battery mode and
supply the load with power. Choose equipment you can leave without UPS supply, disconnect UPS cable from utility
power. Disconnect unnecessary equipment and replace the fuse. Restart the UPS.
Note. Don’t connect laser printers to UPS. Laser printer capacity is usually greater than low end UPS capacity.
7.7 Batteries replacing
Note: Once the battery is disconnected, the loads are not protected from power outages.
• Disconnect UPS cable from utility power socket 220V/50Hz
• Remove the case of UPS
• Disconnect plugs of the battery gently
• Replace the battery
• Make assembly steps in reverse sequence
• Utilize the old battery according to requirements on preservation of the environment
