Example of installation

Counter- measure method	Fix equipment / devices to the panel, then fix the hardware to the slab via an anchor through a turnbuckle.	Fix equipment / devices to the panel, then fix the panel to a pedestals by a turnbuckle.	Penetrating the panel from the equipment / devices, fix them to an anchor through a turnbuckle of the slab immediately below the panel.	Fix to a pedestals fastened to the slab by fixed type panel material.
