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 CAN circuit board.
NOTICE
The GPIO connector of the Strato Pi CAN board must be perfectly aligned to the
Raspberry Pi's GPIO pins. Turning on the Raspberry Pi and/or the Strato Pi CAN board
with the GPIO not correctly connected will damage both the Raspberry Pi and Strato Pi
CAN board.

Strato Pi CAN server

The Strato Pi CAN 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 CAN or 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.

Replacing the RTC backup battery

Strato Pi CAN has a hardware real time clock with a dedicated long-life non-rechargeable
back-up battery.
Strato Pi CAN is shipped with a CR1025 Lithium / Manganese Dioxide (Li/MnO2) battery
installed.
The battery is only used to power the RTC chip when the main power is not available
(when the Raspberry Pi is off). Depending on operating conditions it should last up to two
years if the Strato Pi board is not powered, more if the Strato Pi CAN receives external
power.
WARNING
Improper handling of lithium 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.
KEEP OUT OF REACH OF CHILDREN. Swallowing may lead to serious injury or death in
as little as 2 hours due to chemical burns and potential perforation of the esophagus.
Immediately see doctor.
Replace the RTC lithium battery before it is completely discharged. Replace the battery
every 5 years even if the battery is still working properly. The lithium battery must be
replaced only with an identical CR1025 Lithium / Manganese Dioxide (Li/MnO2) battery.
