6.4 PREVENTIVE MAINTENANCE

DANGER!
Always disconnect the general power supply before changing any electric
component associated to the inverter.
High voltages can be present even after the disconnection of the power supply.
Wait for at least ten minutes for the full discharge of the power capacitors.
Always connect the frame of the equipment to the protection grounding (PE)
at the proper point for that.
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 cards have components sensitive to electrostatic discharges.
Do not touch directly on the components or connectors. If necessary, first touch
the grounded metallic frame or use proper grounding strap.
Do not execute any applied potential test on the inverter!
If necessary, contact WEG.
When installed in proper environment and operating conditions, the inverters require little service.
Table 6.2 on page 35 lists the main procedures and intervals for routine maintenance.
6.3 on page 36 suggests inspections on the product every 6 months after startup.

Instructions
Replacement
Apply power to the inverter with
voltage between 220 and 230 Vac,
single-phase or three-phase, 50 or
60 Hz, for at least one hour. Then,
disconnect the power supply and
wait for at least 24 hours before
using the inverter (reapply power)
