F4901 11a 24v Schematic Install [hot] -

Install a between the 24V power source and Terminal 30. This protects the F4901 and your wiring in case the connected load (the pump/fan) draws too much current or shorts out. Step 4: Making Connections

Connect this to the device you are powering (fan, pump, motor).

This is your switch. When 24V is applied here, the relay "clicks" and completes the circuit. f4901 11a 24v schematic install

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

Connect this directly to your 24V source via an inline fuse. Install a between the 24V power source and Terminal 30

Check the fuse on the Pin 30 line or verify that Pin 87 is securely crimped.

Are you installing this for a like an HVAC blower or a hydraulic pump? This is your switch

Check the voltage at Pin 86. If it’s less than 18-20V, the coil may not have enough power to engage.

Before looking at the schematic, ensure your system matches these parameters: 24V DC (nominal) Maximum Current: 11 Amps
