NOTE
If you are permanently disassembling the installation or part of it, make sure to use the disposal
methods dictated by local regulations.
CAUTION!
Do not remove the six screws on the DC conduit metal panel as it may
harm the inverter sealing and void the warranty.

d'endommager l'étanchéité de l'onduleur et annuler la validité de la
garantie.

Replacing an Inverter

1. Turn OFF the inverter ON/OFF switch, and wait until the LCD indicates that the DC voltage is safe
(<50V), or wait five minutes before continuing to the next step.
WARNING!
If you cannot see the inverter panel, or if a malfunction is indicated on the LCD panel, wait five
minutes for the input capacitors of the inverter to discharge.
Si vous ne pouvez pas voir l'écran de l'onduleur ou si un dysfonctionnement est indiqué sur
l'écran LCD, attendez cinq minutes pour que les condensateurs d'entrée de l'onduleur soient
déchargés.
