L***D* 2 The product worked on testing, however, one electrical wire easily came out from its housing when being prepared for installation by a qualified electrical engineer. The product was therefore returned as faulty. The size of the wires of this product and therefore the wire connectors to integrate the unit into a standard residential electrical circuit, are not to Japan standards. The product also does not carry any Japan standards certification. Be aware of these shortcomings and the fire risk potential.
