The level of inrush current is several times greater than normal input current. (The level of inrush current will differ depending upon the timing when the power supply is turned on, and the impedance of the supply source.) When performing a mega test (insulation test) on signal transmission cables, be sure to remove the cables from the driver (transducer) and signal conditioner. In addition, be sure to short-circuit the cables before reconnecting them after a mega test to discharge any electrical charge. Connecting cables with an electrical charge to the driver or signal conditioner could result in damage to the product. Perform the following measures to ensure the stability of the system. - Be sure to install surge killers on the product and related equipment, as well as on the relays around the signal cables connecting the equipment. - Tighten installation screws to securely fix all units. - Install an interlock function on the system to prevent misoperation in the event of trouble with the product. If any of the following situations occur, stop using the product and contact the sales office where it was purchased for assistance. Continuing to use the product in abnormal conditions could result in fire or damage. - When the product emits foul odors - When the product becomes abnormally hot - When the product falls or is dropped - When the product s case becomes damaged When storing the product, place it in a location free from direct sunlight.
