Battery and external rechargeable battery This product uses a small lithium non-rechargeable battery to power its internal real time clock (RTC). It also optionally uses an external rechargeable lead-acid battery for the uninterruptible power supply. Strato Pi UPS User Guide... - Page 7 Only use a lead-acid battery with electrical ratings recommended in the technical specifications for this product. Follow the battery manufacturer's instructions when installing the external UPS battery (not provided). Dispose of used batteries according to local regulations and the battery manufacturer's instructions. Strato Pi UPS User Guide...

Page 8: Introduction
Strato Pi UPS is available as a bare board or fully assembled unit including a Raspberry Pi 3 Model B or B+ in a standard DIN-rail case. -
Page 9: Features
✓ integrated uninterruptible power supply, with external lead-acid 12V battery ✓ 1.1A resettable fuse on battery input ✓ auxiliary power supply output voltage, to power external devices through Strato Pi UPS ✓ simple UPS status and control via the GPIO pins of the Raspberry Pi board ✓... -
Page 10: Usage And Connections
Strato Pi’s circuit board. NOTICE 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. -
Page 11: Strato Pi Ups Server
The battery is only used to power the RTC chip when the main or UPS battery 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 UPS receives external power. - Page 12 The RTC backup battery holder is soldered to the bottom layer of the circuit board, between the GPIO connectors. In the Strato Pi UPS server, the battery is not accessible from the outside. You should first remove the case top body to gain access to the Strato Pi UPS circuit board.

Page 13: Terminal Block
8. Insert the microSD card. RTC BACKUP BATTERY Terminal block Strato Pi UPS has a 10 positions terminal block for power, battery, auxiliary power supply output and serial connections. The maximum conductor cross section is 1.5 mm (16 AWG), or 0.5 mm when using ferrules (highly recommended). -
Page 14: Power Supply
When a Strato Pi UPS board is used, never connect the Raspberry Pi micro-USB power plug. The Strato Pi UPS power supply stage is optimised to deliver up to 3A at 5V to the Raspberry Pi. Because Strato Pi has a 1.1A resettable fuse (polyfuse) on the power supply line, the maximum current that its regulator can deliver is also limited by this fuse, and depends on the input voltage. -
Page 15: Auxiliary Power Supply Output
When the Raspberry Pi is turned off by the Strato Pi UPS controller, the aux power supply output is also switched off. -
Page 16: Software Installation And Configuration
Software installation and configuration All features of Strato Pi UPS, except the real time clock, are controlled via dedicated GPIO pins and can be used with any operating system and programming language that supports the GPIO pins control on Raspberry Pi. The real time clock is interfaced via the I C serial bus. -
Page 17: Testing The Real Time Clock
If the RTC address is not detected, the cause could be a hardware problem, on the Strato board or the Raspberry Pi. If you have another Pi or Strato board, try swapping them to isolate the faulty board. Strato Pi UPS User Guide... -
Page 18: Disabling Bluetooth, Wifi And The Serial Console
If you are using Strato Pi’s serial ports for your applications, you also need to disable the Linux serial console, otherwise it will send console data to the serial port. Disable the ttyAMA0 console service: sudo systemctl disable serial-getty@ttyAMA0.service Edit the /boot/cmdline.txt file and delete the serial console configuration: console=serial0,115200 Strato Pi UPS User Guide... -
Page 19: Using Strato Pi Ups
Serial port Strato Pi UPS uses the Raspberry Pi standard UART TX/RX pins on the GPIO connector to implement a standard serial port with support for both RS-232 and RS-485. -
Page 20: Buzzer
RS-485 JUMPERS POSITION Buzzer Strato Pi UPS has an on-board buzzer that can be controlled using GPIO20. Simply set GPIO20 to high to emit a continuous sound, and back to low to stop. The buzzer is not intended to emit sound indefinitely and could be damaged doing so. -
Page 21: Ups
Strato Pi will wait 60 seconds more, then power cycle the Raspberry Pi. Note that Strato Pi UPS will power cycle the Raspberry Pi even if GPIO16 is not set high. In this case the power cycles occurs 120 seconds after the heartbeat timeout. -
Page 22: Power Cycle
Power cycle You can start a delayed power cycle by rising Raspberry Pi’s GPIO16 pin. When GPIO16 is set to high, Strato Pi UPS will wait 60 seconds and then power off the Pi board for 5 seconds. The power cycle also affects the VSOUT auxiliary power supply output. -
