6.4 PREVENTIVE MAINTENANCE

DANGER!
Always turn off the mains power supply before touching any electrical component
associated to the inverter.
High voltages may still be present even after disconnecting the power supply.
To prevent electric shock, wait at least ten minutes after turning off the input
power for the complete discharge of the power capacitors. Always connect the
equipment frame size to the protective ground (PE). Use the adequate connection
terminal at the inverter.
DANGER!
Toujours couper l'alimentation électrique avant de toucher les composants
électriques de l'onduleur. Des hautes tensions peuvent encore être présentes
même après la déconnexion de l'alimentation. Pour éviter tout choc électrique,
attendez au moins 10 minutes après la mise hors tension de la puissance d'entrée
pour la décharge complète de la puissance des condensateurs. Branchez
toujours l'équipement Taille de cadre à la terre de protection (PE). Utilisez la borne
de connexion adéquat à l'onduleur.
ATTENTION!
The electronic boards have electrostatic discharge sensitive components.
Do not touch the components or connectors directly. If necessary, first touch the
grounded metallic frame size or wear a ground strap.
Do not perform any withstand voltage test: if necessary, consult WEG.
The inverters require low maintenance when properly installed and operated.
