If the schematic shows a diode symbol, reversing A1/A2 will short your power supply.
The F4901 11A is typically an advanced GPS tracking terminal designed for fleet management, logistics, and heavy machinery. It is commonly used in commercial vehicles (trucks, buses) which utilize 24V electrical systems.
Key Features typically include:
After installation:
Before drilling or wiring, verify your unit matches the F4901 specs.
When driving a solenoid or motor, add a flyback diode (e.g., 1N5404) across the load, cathode to LOAD, anode to GND. The F4901’s internal body diode does not clamp negative inductive kick sufficiently.
