(3) do not store this product in an environment of dust or corrosive gas (salt, acid, alkali etc.). (4) be sure to use this product under recommended operating conditions specified in section5. do not use this product over absolute maximum ratings specified in section4. 13 13 13 13- - - -3 3 3 3 mounting mounting mounting mounting (1) when designing equipment, high voltage part of inverter, that is the wiring between transformer and output connector, must keep the distance of 4mm or more from any other conductive materials. if there are any conductive materials around the inverter, we recommend to insert insulator. (2) do not bundle the high side and the low side of the cable between the output connector and the lamp not to increase leakage current which does not contribute to light generation. do not twist the cable. (3) make sure that foreign particles do not get into the module to prevent malfunction caused by short-circuit of high voltage part of inverter. 13 13 13 13- - - -4 protective circuit 4 protective circuit 4 protective circuit 4 protective circuit (1) this product has built-in fuse to prevent from smoking or firing caused by over current. to make sure this operation, use the power supply with capacity of more than twice of rated current. 13 13 13 13- - - -5 handling 5 handling 5 handling 5 handling (1) be careful of electric shock, for there stays a high voltage in the internal circuit. turn off the power supply before pushing in and pulling out the input or output connectors. (2) do not touch the exposed part of the transformer on the inverter. it may cause electric shock. (3) excessive mechanical force to the electric parts and printed circuit board of the inverter may become the cause of any trouble such as pattern exfoliation. handle this inverter carefully. (4) please don?t give any shock to the transformer of the inverter or don?t hurt the signal cable. even rare short-circuit may become the cause of smoke or fire. (5) do not stack the inverters. 13 13 13 13- - - -6 indication 6 indication 6 indication 6 indication (1) there is no indication to warn you about the high voltage. make sure that only authorized technician should handle the inverter. if the equipment is designed so that the inverter is possibly touched by outsider, it is requested to indicate warnings clearly for fear of electric shock or burns.
