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.
AVERTISSEMENT!
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.
