¡Atención! Wire a fonte de alimentação de DC Usando os talões apropriados na
extremidade da fiação. Ao conectar a potência, a seqüência apropriada da fiação é
moída para moer, +RTN a +RTN, então –48 V a –48 V. Ao desconectar a potência,
a seqüência apropriada da fiação é –48 V a –48 V, +RTN a +RTN, moeu então para
moer. Anote que o fio à terra deve sempre ser conectado primeiramente e
desconectado por último. Anote que o fio à terra deve sempre ser conectado
primeiramente e desconectado por último.
Varning! Korrekt kopplingssekvens ar jord till jord, +RTN till +RTN, –48 V till –48 V.
Korrekt kopplas kopplingssekvens ar –48 V till –48 V, +RTN till +RTN, jord till jord.

DC Power Wiring Terminations Warning for EX Series Switches
WARNING: When stranded wiring is required, use approved wiring terminations,
such as closed-loop or spade-type with upturned lugs. These terminations must be
the appropriate size for the wires and must clamp both the insulation and conductor.
Waarschuwing Wanneer geslagen bedrading vereist is, dient u bedrading te gebruiken
die voorzien is van goedgekeurde aansluitingspunten, zoals het gesloten-lus type of
het grijperschop type waarbij de aansluitpunten omhoog wijzen. Deze aansluitpunten
dienen de juiste maat voor de draden te hebben en dienen zowel de isolatie als de
geleider vast te klemmen.
Varoitus Jos säikeellinen johdin on tarpeen, käytä hyväksyttyä johdinliitäntää,
esimerkiksi suljettua silmukkaa tai kourumaista liitäntää, jossa on ylöspäin käännetyt
kiinnityskorvat. Tällaisten liitäntöjen tulee olla kooltaan johtimiin sopivia ja niiden
tulee puristaa yhteen sekä eristeen että johdinosan.
Attention Quand des fils torsadés sont nécessaires, utiliser des douilles terminales
homologuées telles que celles à circuit fermé ou du type à plage ouverte avec cosses
rebroussées. Ces douilles terminales doivent être de la taille qui convient aux fils et
doivent être refermées sur la gaine isolante et sur le conducteur.
Warnung Wenn Litzenverdrahtung erforderlich ist, sind zugelassene
Verdrahtungsabschlüsse, z.B. für einen geschlossenen Regelkreis oder gabelförmig,
