10.6 REVERSE POLARITY AT THE DC INPUT TERMINALS

The Positive of the battery should be connected to the Positive DC input terminal of the
inverter and the Negative of the battery should be connected to the Negative DC input
terminal of the inverter. A reversal of polarity (the Positive of the battery wrongly con-
nected to the Negative DC input terminal of the inverter and the Negative of the bat-
tery wrongly connected to the Positive DC input terminal of the inverter) will blow the
external / internal DC side fuses. If the DC side fuse is blown, the inverter will be dead.
The Status LED (2, FIG 6.1) and the GREEN indication light on the GFCI will be switched
OFF and there will be no AC output.

i

INFO

Reverse polarity connection is likely to damage the DC input circuitry. The
internal fuse(s) should be replaced with the correct size of fuse shown under
specifications. If the unit does not work after replacing the fuse(s), it has been
permanently damaged and will require repair / replacement (

Please read

Section 11 - “Troubleshooting Guide” for more details

).

i

INFO

Un inversement des polarités va probablement endommager les circuits
d'entrée CC. Il faut remplacer le(s) fusible(s) avec un/des fusible(s) d'une taille
pareille. Si après l'installation, l'appareil ne marche pas, c'est qu'il soit endom-
magé en permanence et aura besoin d'une réparation ou un remplacement
(Pour des renseignements supplémentaires, veuillez regardez à la Section 11 -
«Guide de Dépannage»).

!

CAUTION!

Damage caused by reverse polarity is not covered by warranty! When making
battery connections on the input side, make sure that the polarity of battery
connections is correct (Connect the Positive of the battery to the Positive termi-
nal of the unit and the Negative of the battery to the Negative terminal of the
unit). If the input is connected in reverse polarity, DC fuse(s) inside the inverter /
external fuse will blow and may also cause permanent damage to the inverter.

!

ATTENTION!

Des dégats causés par un inversement de polarités ne sont pas couverts par
la garantie! Quand vous faites des connexions à la batterie du côté d'entrée,
veuillez assurer que les polarités sont mises du bon côté (Lié le Positif de la
batterie à la borne Positive de l'appareil et le Négatif de la batterie à la borne
Négative de l'appareil). Si les polarités de l'entrée sont mises à l'envers, le
fusible CC externe du côté d'entrée va s'exploser et pourrait causer des dégâts
permanents à l'onduleur.
