Disconnect the main 24V power source before beginning. Since this unit handles 11A, an accidental short can cause significant sparking or damage to sensitive electronics. Step 2: Wire Sizing
Run a ground wire from the chassis or battery negative to .
This is your switch. When 24V is applied here, the relay "clicks" and completes the circuit. f4901 11a 24v schematic install
Before looking at the schematic, ensure your system matches these parameters: 24V DC (nominal) Maximum Current: 11 Amps
for the F4901 variant you hold, as pin numbers can occasionally vary by brand (e.g., Bosch style vs. DIN rail style). Disconnect the main 24V power source before beginning
Connects to the negative (-) terminal of the 24V battery or power supply.
Ensure your total load does not exceed 11A. If you are running a motor, remember that "startup surge" can sometimes double the running amperage. Summary Checklist Voltage: 24V DC Fuse: 15A Wire: 14 AWG Ground: Solid chassis or battery connection This is your switch
To handle 11 Amps safely over a standard distance, use . Using thinner wire (like 18 AWG) will result in a voltage drop and potential fire hazard. Step 3: Circuit Protection
