How do you hook up fan motor to fan relay?

To hook up a fan motor to a fan relay, first ensure the power is off to avoid electrical shock. Connect the fan motor's positive lead to the relay's output terminal, typically labeled as "NO" (Normally Open) or "COM" (Common), depending on the relay configuration. Attach the negative lead of the fan motor to the ground or neutral wire. Finally, connect the relay's coil terminals to a control switch or sensor to activate the relay when needed.
