6.4 INFORMATION NECESSARY FOR CONTACTING TECHNICAL SUPPORT

NOTE!
For technical support and servicing, it is important to have the following information in hand:
Inverter model;
Serial number, manufacturing date, and hardware revision that are listed in the product nameplate
(refer to the section 2.4);
Installed software version (check parameter P0023);
Application data and inverter settings.

6.5 PREVENTIVE MAINTENANCE

DANGER!
Always turn off the mains power supply before touching any electrical component associated to
the inverter.
High voltage may still be present even after disconnecting the power supply.
To prevent electric shock, wait at least 10 minutes after turning off the input power for the complete
discharge of the power capacitors.
Always connect the equipment frame to the protective ground (PE). Use the adequate connection
terminal at the inverter.
DANGER!
Débranchez toujours l'alimentation principale avant d'entrer en contact avec un appareil électrique
associé au variateur.
Des tensions élevées peuvent encore être présentes, même après déconnexion de l'alimentation.
Pour éviter les risques d'électrocution, attendre au moins 10 minutes après avoir coupé l'alimentation
d'entrée pour que les condensateurs de puissance soient totalement déchargées.
Raccordez toujours la masse de l'appareil à une terre protectrice (PE). Utiliser la borne de connexion
adéquate du variateur.
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 or wear a ground strap.
The inverters require low maintenance when properly installed and operated. The table 6.3 presents the main
procedures and time intervals for preventive maintenance. The table 6.4 provides recommended periodic
inspections to be performed every 6 months after the inverter start-up.
Do not perform any withstand voltage test!
If necessary, consult WEG.
