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
Optional: Used for "normally closed" applications (power flows when the relay is OFF). 3. Installation Steps Step 1: Safety First f4901 11a 24v schematic install
F4901 11A 24V Schematic & Installation Guide The is a specific industrial-grade relay or solenoid valve controller (often found in heavy-duty HVAC or hydraulic systems) designed to handle high-current loads in a 24V DC environment. Disconnect the main 24V power source before beginning
Run a ground wire from the chassis or battery negative to . Check the voltage at Pin 86
Check the voltage at Pin 86. If it’s less than 18-20V, the coil may not have enough power to engage.
Connect this directly to your 24V source via an inline fuse.
Connects to the negative (-) terminal of the 24V battery or power supply.
