A-6APPENDIX A: SAFETY INFORMATION

Gervaar: Deze eenheid werkt onder extra lage spanning (SELV, Safety Extra Low Voltage) volgens norm IEC 950. Er wordt uitsluitend aan deze norm voldaan zolang de apparatuur waarmee de eenheid is verbonden, ook werkt onder SELV.

Vaara: Tämä yksikkö sisältää kansainvälisen turva- standardin IEC 950 mukaisia SELV (Safety Extra Low- Voltage) -suojajännitepiirejä. Yksikkö täyttää standardissa kuvatut ehdot vain, jos laite, johonyk- sikkö liitetään, käyttää SELV-piirejä.

Pericolo: Questa unità funziona in condizioni di bassissima tensionedi sicurezza (SELV, Safety Extra Low Voltage) secondo l’IEC 950.Tali condizioni sono rispettate solo se anche l’apparecchiaturaa cui l’unità è collegata funziona in SELV.

Fare: Dette utstyret drives med strøm fra kretser med ekstra lav spenning (SELV-kretser) i henhold til standarden IEC 950. Denne spenningen opprettholdes kun dersom utstyret som det er koblet til, også drives av såkalte SELV-kretser.

Perigo: Esta unidade funciona sob condições SELV (Safety Extra LowVoltage - Tensão Muito Baixa, de Segurança), de acordo com anorma IEC 950. O estabelecido nesta norma só poderá ser mantidose o equipamento ao qual a unidade for ligada também funcionarsob aquelas condições SELV.

Peligro: Esta unidad opera bajo condiciones SELV (Safety Extra Low Voltage /Voltaje Extra Bajo de Seg- uridad) de acuerdo a la norma IEC 950, sibien tales condiciones únicamente se mantienen si el equipo alque se conectan es asimismo operacional bajo SELV.

Fara: Den här enheten arbetar under villkoren för kyddsklenspänning (Safety Extra Low Voltage) enligt IEC 950. Dessa villkor uppfylls endast om utrustning till vilken enheten ansluts också arbetar med sky- ddsklenspänning.
