Warnung Der Erdanschluß muß bei der Installation der Einheit immer zuerst
hergestellt und zuletzt abgetrennt werden.
Avvertenza In fase di installazione dell'unità, eseguire sempre per primo il
collegamento a massa e disconnetterlo per ultimo.
Advarsel Når enheten installeres, må jordledningen alltid tilkobles først og
frakobles sist.
Aviso Ao instalar a unidade, a ligação à terra deverá ser sempre a primeira a
ser ligada, e a última a ser desligada.

DC Power Wiring Sequence Warning
WARNING: Wire the DC power supply using the appropriate lugs. When
connecting power, the proper wiring sequence is ground to ground, +RTN to
+RTN, then –48 V to –48 V. When disconnecting power, the proper wiring
sequence is –48 V to –48 V, +RTN to +RTN, then ground to ground. Note
that the ground wire must always be connected first and disconnected last.
Waarschuwing De juiste bedradingsvolgorde verbonden is aarde naar aarde,
+RTN naar +RTN, en –48 V naar – 48 V. De juiste bedradingsvolgorde
losgemaakt is en –48 naar –48 V, +RTN naar +RTN, aarde naar aarde.
Varoitus Oikea yhdistettava kytkentajarjestys on maajohto maajohtoon,
+RTN varten +RTN, –48 V varten – 48 V. Oikea irrotettava kytkentajarjestys
on –48 V varten – 48 V, +RTN varten +RTN, maajohto maajohtoon.
Attention Câblez l'approvisionnement d'alimentation CC En utilisant les
crochets appropriés à l'extrémité de câblage. En reliant la puissance, l'ordre
approprié de câblage est rectifié pour rectifier, +RTN à +RTN, puis –48 V à
–48 V. En débranchant la puissance, l'ordre approprié de câblage est –48 V
