electric shocks.

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.
