4. Package Contents
The standard package for the Teltonika BAT120 includes:
- Teltonika BAT120 Uninterrupted Power Supply Unit
- Mounting hardware (e.g., screws for surface mounting, clips for DIN rail mounting - exact items may vary)
- Quick Start Guide (not included in this manual, but typically provided with the product)
5. Setup and Installation
Follow these steps to set up your Teltonika BAT120 UPS:
- Choose Mounting Location: Select a suitable location for the BAT120. It can be mounted on a DIN rail or directly on a surface using appropriate screws. Ensure the location is dry, well-ventilated, and within reach of power sources and the device it will power.
- Connect Power Input: Connect your UK PSU (9-30VDC) to the IN PWR 4-pin DC connector on the BAT120. Ensure the connection is secure.
- Connect Power Output: Connect the device you wish to power (e.g., Teltonika router) to the OUT PWR 4-pin DC connector on the BAT120. The output voltage will be 12VDC when operating from the battery.
- Power On: Locate the On/Off slider switch on the unit and slide it to the 'On' position.

6. Operation
Once connected and powered on, the Teltonika BAT120 operates automatically to provide uninterrupted power.
6.1. Power Modes
- Passthrough Mode: When external power is supplied to the IN PWR port, the BAT120 passes through the input voltage (9-30 VDC) to the OUT PWR port and simultaneously charges its internal battery.
- Battery Mode: In the event of a power outage or if the input power is disconnected, the BAT120 automatically switches to battery mode, providing a stable 12VDC output to the connected device for up to 6 hours, depending on the load.
6.2. LED Indicators
The BAT120 features several LED indicators to show its status:
- IN PWR LED: Indicates the status of the input power.
- OUT PWR LED: Indicates the status of the output power.
- 4 x Power Status LEDs: These LEDs indicate the charge level of the internal battery.

6.3. Alarm Output
The BAT120 includes an alarm output (1 x Active HIGH output, max 12 V, 2.5 mA) that can be configured with a compatible Teltonika router to trigger custom alerts, such as notifications for power outages.
7. Maintenance
The Teltonika BAT120 is designed for minimal maintenance. Follow these guidelines to ensure its longevity:
- Cleaning: Periodically clean the exterior of the unit with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the unit is disconnected from power before cleaning.
- Ventilation: Regularly check that the ventilation openings are clear of dust and debris to prevent overheating.
- Battery Life: The internal Lithium-Ion battery has a finite lifespan. Over time, its capacity may decrease. If you notice a significant reduction in backup time, the unit may need servicing by qualified personnel.
- Storage: If storing the unit for an extended period, ensure it is fully charged and stored in a cool, dry place. Recharge periodically to maintain battery health.
