Take the Pi UPS, the battery pack and the press-
stud connection out of their packages.
Insert the six AA batteries (not included in the
delivery) into the battery pack.
Now connect the battery pack with the Pi UPS
using the clamp-connection ( ).
Please note that the wires from the battery pack are
connected correctly to the press-stud connection.
The press-stud connection uses two small gray
buttons. You open the clips with these while pressing
on them.
Then insert the wires accordingly: The black wire
into the hole which says GND. Both wires are fixed
when you release the buttons again.
Carefully plug the Pi UPS on the
GPIO port of the Raspberry Pi.
Important: Please connect the CW2.
Pi UPS carefully with the GPIO port of
the Raspberry Pi.

You don’t need to connect a USB
cable to the Raspberry Pi.
The power supply system for
the Raspberry Pi must be connected to
the Pi UPS too ( !
Now everything is set up and it is safe to power up your Raspberry Pi and install the
CW2. software which you can download here: http://piups.net/support. This program will
work in the background without any kind of graphical user interface.
The Pi UPS is ready to use!
Have fun!

The Pi UPS was designed
solely for the safe shutdown of the
Raspberry Pi minicomputer and not
for running the Raspberry Pi perma-
nently with batteries. Doing this could
harm the Pi UPS.
On behalf of our natural environment you as a consumer are called to recycle as much of
the used materials as possible. So please bring damaged or unused electronic devices to
the public collection points for electronic scrap.
~ Classification after IEC 62040-3: Class 1, part 3, which means that as soon as voltage
gaps happen, the UPS switches to batteries. No recharge feature implemented
~ Primary voltage and battery voltage: UP=5V (USB) => ~ Primary voltage: UP=5V (USB)
~ Allowed battery voltage: U SinMax=7.5V-12V
~ Maximum current with battery pack: IMax=1,000mA
~ Communication between Pi and the Pi UPS through I²C
~ Power supply for the Pi through GPIO, therefore no connection to the Pi needed
~ Weight Pi UPS alone: 125g
~ Dimensions: Width 55mm, Depth 40mm, Height 20mm
~ IN1: Primary power supply through Micro USB
~ IN2: Secondary power supply through press-stud connection
~ LED1: All good, default state
~ LED2: Batteries weak or empty
~ LED3: Emergency mode, power supply through
secondary power supply
