1. קאָננעקט אַרייַנשרייַב מאַכט: Connect your DC power source (e.g., 12-85V DC supply, solar panel) to the IN+ and IN- terminals. Ensure correct polarity.
2. Connect Output Load/Battery: Connect your load or battery to the OUT+ and OUT- terminals.
3. Anti-Backflow Diode (for Battery Charging): If charging a rechargeable battery, and you are not a professional, connect an appropriate anti-backflow diode in series with the OUT+ terminal to prevent reverse current flow.
4. Connect External Temperature Probe (Optional): For over-temperature protection during battery charging, connect the NTC temperature probe to the dedicated interface and attach the probe to the battery.

WARNING: Ensure all connections are secure and correct before applying power. Incorrect wiring can damage the device and connected equipment.
