Note: there are two battery pack options for UPS, 16 units and 20 units. Users can choose the different
battery pack voltage in accordance with different requirements. The default units of batteries to UPS is 16,
and users can not connect 16 batteries to UPS if the UPS should be connected 20 units. Please strictly follow
the procedure of batteries connection, or will get electric shocks.
1. Set the battery switch at ‘OFF’ position, then install batteries in series.
2. Connecting the cables to batteries firstly, or you may get electric shocks if you connect the cables to UPS
firstly. You’d better connect the red cable to battery positive pole ‘+’, black to negative pole ‘-’, so that it would
be much easier to distinguish.
3. Select proper cables to connect the batteries and UPS is very important, and there should be a switch
connected between the battery pack and UPS.
4. Finally, without any load, set on the battery switch which is connected between the UPS and the battery
pack, so that UPS can get connected to batteries, then switch in the mains power, after doing all of those, the
batteries will be charged by the UPS automatically.
