Troubleshooting and Maintenance

CFW11W | 3-4

3.2.

NECESSARY INFORMATION TO CONTACT TECHNICAL SUPPORT

NOTE!

For technical support and servicing, it is important to have the following information at hand:

Inverter model.

Serial number, manufacturing date and hardware revision that are listed in the

product nameplate.

Installed software version (check P0023).

Application data and inverter settings.

3.3.

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 appropriate

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. Table 3.2 presents the main

procedures and time intervals for preventive maintenance. Table 3.3 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.
