SPECIFICATIONS
The grounding conductor should be selected in terms of current carrying
capacity. Use a grounding cable for all ground connections of devices that are
connected to the UPS. There is a risk of damage to electrical circuits without
proper grounding or grounding without approval.
When installing the UPS, if the wrong specification cable is used, it may be
dangerous to the health of the user and the device itself.
The UPS may only be repaired by an Authorized Service Center. Any attempt by
the user to open and repair it may be dangerous.
Attaching magnetic data carriers to the power adapter may damage your data.
INSTALLATION
UNPACK AND CHECK
The package includes: UPS, operating instructions, warranty card and 2 wires
for connecting the battery.
Please check the rating label/plate to ensure that the UPS is as ordered. Make sure that the housing of the unit is not damaged! If you notice any damage, please contact the seller immediately! Keep the packaging for possible transport.
PLACEMENT
This power supply is intended for indoor use only!
- Install the UPS in a cool, dry and clean place.
- Install the UPS in a well-ventilated area, keep a minimum distance of 50 cm between the UPS and the wall.
- Keep away from unstable ground or sources of excessive vibration.
- Keep away from windows, dust, moisture and cold places.
- Keep away from fire and heat sources.
- Keep away from corrosive gas or fluid.
- Operating temperature: – 10°C~ +40°C.
- Operating humidity: 10% ~ 90% (non-condensing).
The expected operating altitude of this UPS is less than 1000m. If the installation site is above 1000m above sea level, the load capacity will be correspondingly lower, as shown in the table below.
Special Precautions:
When the UPS input comes from a generator:
- a. Output power capacity must be higher than the UPS rating, otherwise the UPS and generator may not work properly.
- b. Output frequency of generator must be in range from 45 to 65Hz, and waveform must be sine wave, otherwise the UPS and generator may not work properly.

INSTALLATION OF BATTERY
- A. Make sure using the correct battery cable. The over-current ability of the battery cable should not be less than the maximum discharging current. Please refer to the below table.
- B. Please make sure that the battery voltage is correct as specified on the case.
- C. Disconnect the UPS from mains power completely.
- D. Connect the negative (-) of battery to the BATTERY TERMINAL “-” of UPS, and positive (+) to the BATTERY TERMINAL”+”.
- E. Before replacing battery, turn off the UPS and disconnect it from mains power.
This UPS is designed for long-time backup, the connected battery should be at least 20AH because the initial charging current is at least 3A. Smaller battery could be damaged easily.
CONNECTION TO MAINS POWER AND TO LOAD
- A. Plug the UPS into the wall socket.
- B. Make sure the loads/appliances are turned off before connection.
- C. Connect the loads/appliances to the UPS one by one. Make sure the total capacity of connected appliances does not exceed the rated capacity of UPS.
OPERATION
TURN ON THE UPS
Press the POWER SWITCH, The UPS is switched on and deliver output till the UPS
gives one beeping sound.
Then switch on the connected appliances one by one. If there are 2 or many
appliances, please turn on the biggest appliance at the first, the smallest
appliance at the last, according to their rated power.
TURN OFF THE UPS
Turn off the devices one by one, and then press the “SWITCH” button, when you
hear one beep, it means that the UPS will turn off.
Even if the output of UPS is turned off, the UPS is still working to charge the battery, the UPS is not totally switched off. To switch it off completely, disconnect the UPS from the mains power.
CHARGING CURRENT SELECTOR
It’s recommended to select the charging current as below:
Wrong selection of the charging current may lead to the damage of battery in charging process!
