6.3 DATA TO CONTACT THE TECHNICAL ASSISTANCE
For information or service request, it is important to have at hand the following data:
Drive model.
Serial number and manufacturing date of the product found in the identification label
(refer to
section 2.4 - Identification Labels
).
Software version installed (see P0023 and P0024).

6.4 PREVENTIVE MAINTENANCE
DANGER!
Always disconnect the general power supply before changing any electric
component associated to the drive.
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.
ATTENTION!
The electronic boards have components sensitive to electrostatic
discharges.
Do not touch components or connectors directly. If necessary, first touch
the grounded metallic frame or use a proper grounding strap.
Do not execute any applied potential test on the drive. If necessary,
contact WEG.
When installed in proper environment and operating conditions, the drives require little
service.
Table 6.2
lists the main procedures and intervals for routine maintenance.
