Plug in the USB power to USB-In port on Pi-UpTime UPS 2.0. The green LED comes on indicating 
battery is charging. If there is no light, battery is charged.  

6.

 

Once the Pi-UpTime UPS 2.0 is connected to the Pi (the 2x20 pin connectors are mated), insert 
the shunt on Jumper J3, or if a switch is installed, turn the switch to on. This applies the power. 
The Pi will boot up once power is applied.
