Both ends of the relay are to be secured firmly so that the socket hooks on the top surface of the relay. GOOD 3. Remove the relay, applying force in the direction shown below. 4. In case there is not enough space to grasp relay with fingers, use screwdrivers in the way shown below. NO GOOD NOTES 1. Phase synchronization of AC-load switching In case of switching the contact synchronized with phase of load voltage, the life of contact might be shorter or contact failure might be caused. Please confirm this matter in the actual system in this case. If necessary, the phase control would be recommended. Ry Load Vin Load voltage 2.
