use the shielding function the metallic cable support systems, these must in- cluded the equipotential bonding both sides. After damage, the lights or the LED drivers can only repaired high cost. Independently this, the surge protection system should installed for the entire lighting sys- tem.6 LED internal lighting buildings and halls LED lighting systems industrial plants and adminis- trative buildings are usually destroyed high voltages, coupled inductively switching opera- tions. In industrial and sports halls, the luminaires are in- stalled great height. A risk analysis according IEC 62305 can used to determine whether external lightning protection system required not.LED lighting system indoor car park 3. Surge protection devices must used the subdis- tributor supplied. lightning protection sys- tem, the supply cables the entrance the building must protected using suitable lightning current ar- restors. However, the luminaires are of- ten from this distributor. The usually very long supply lines have high poten- tial for inductive coupling surge voltages. If the luminaires are, for example, mounted directly be- neath the cable support systems, then the surge pro- tection can also inserted junction box front of the luminaires.4. Connection the protection device The protection device ÜSM-LED 230 can installed in series with parallel the luminaires. As the minimum lighting strength required the work- station can lead accidents errors, immediate ac- tion required. The differ- ing connection can used maximise availability (parallel connection) switch off the luminaire if there defect the protection device (serial con- nection).2. protect the LED drivers and the light, protection device then re- quired directly front the electronic components.
