Hardware Installation
Strato Pi UPS board
The Strato Pi UPS board is supplied with all connectors pre-installed. No soldering is
required. You should connect Strato Pi to Raspberry Pi through the GPIO connector. Use
appropriate turrets/spacers to firmly bolt the two boards together, ensuring that no
conductive part of one board touches any part of the other board.
Be particularly careful to ensure there is enough clearance between the Ethernet and USB
connectors and the bottom of Strato Pi’s circuit board.
The GPIO connector of the Strato Pi UPS board must be perfectly aligned to the
Raspberry Pi's GPIO pins. Turning on the Raspberry Pi and/or the Strato Pi UPS board
with the GPIO not correctly connected will damage both the Raspberry Pi and Strato Pi
UPS.
Strato Pi UPS server
The Strato Pi UPS server comes pre-assembled with a Raspberry Pi 3 Model B or B+ or
Raspberry Pi 4 Model B board, in a plastic standard DIN-rail case.
There is no need to open the case, unless a change in the RS-485 termination resistors is
required (see below).
The Micro SD card (not provided) can be inserted through a small opening on the side of
the case. Use a small pen or paper clip to gently push the card in its slot.
The external UPS battery
To take advantage of the UPS features of Strato Pi, you can connect an external lead acid
rechargeable battery to the BATT terminals of the Strato Pi UPS terminal block. See the
connection diagram above.
Improper handling of lead acid batteries can result in an explosion of the batteries and/or
release of harmful substances.
Worn-out or defective batteries can compromise the function of this product.
Replace the battery every 5 years even if the battery is still working properly.
Only use a lead acid battery with electrical ratings recommended in the technical
specifications for this product (12V 1.2Ah max).
