In case there is not enough space to direction shown below. grasp relay with fingers, use screwdrivers in the way shown below. 2. Both ends of the relay are to be secured firmly so that the socket hooks on the top surface of the relay. Notes:1.Exercise care when removing relays. If greater than necessary force is applied at the socket hooks, deformation may alter the dimensions so that the hook will no longer catch, and other damage may also occur.
