6 WANINGS WANING: his symbol indicaes danger. ead he following warnings before insalling, connecing or using he device: If he power solid sae uni is used in applicaions wih risk of injury o people, machines, or maerials, auxiliary alarm devices mus be employed. I is also advisable o be able o check for ripping of alarms during normal operaion; follow insrucions precisely when connecing he heasink; always use cables ha are suiable for he volage and curren levels indicaed in he echnical specificaions; DO NOT operae he device in rooms wih dangerous (inflammable or explosive) amosphere; During coninuous operaion, he hea sink can reach up o 100 C, and says a a high emperaure even afer he device is urned off due o hermal ineria; herefore, DO NOT ouch i and avoid conac wih elecrical wires; do no work on he power par wihou firs disconnecing elecrical power o he panel; do no remove he cover when he device is powered! Insallaion: ground he heasink conneced o he power module; power supply lines mus be separaed from device inpu and oupu lines; always check ha he supply volage maches he volage indicaed on he device label; avoid dus, humidiy, corrosive gases and hea sources; respec he insallaion disances beween one device and anoher (o allow for dissipaion of generaed hea). o keep air in movemen, we advise you o insall a fan near he GTZ group in he elecrical panel conaining he GTZs.; Mainenance: a regular inervals, check operaion of he cooling fans and clean all air venilaion filers; repairs mus be done ou only by rained and specialized personnel. Cu power o he device before accessing inernal pars. do no clean he box wih solvens derived from hydrocarbons (richloroehylene, gasoline, ec.). Using such solvens will compromise he device's mechanical reliabiliy. Use a clean cloh moisened wih ehyl alcohol or waer o clean exernal pars in plasic. Service: GEFAN has a service deparmen.
