visually at the intervals stated in Appendix
A - ACS2000 maintenance schedule, located
on the CD, and pay attention to the
following items:
• Condensation inside the drive

temperature and humidity of the drive
See the drive Rating label located on the

information on permitted air temperature
range.
• Dust built-up inside the drive room and inside the
drive
• Signs for overheated components, wires, cables
or busbars
• Corrosion on circuit boards, connectors or
busbars
• Appropriate fastening of cables and wires and
connections of cable shields
See Chapter Electrical installation if further
information is required
• Integrity of cable insulation
• The outer cable sheath must not be damaged
• Correct type of signal and power cables
See Appendix H - Power Cable

Cleaning
Dust on electrical components and wiring can
cause malfunction and damage the components.
Dust and moisture can build up in loose
connections and cause loss of low-level signals.
For these reasons, the cabinet should be checked
regularly and cleaned if necessary.
When cleaning the drive cabinet, mind the
following:
• Cover equipment or assemblies to prevent dirt
from falling into it
• The drive contains components which are
sensitive to electrostatic discharge. Therefore,
take electrostatic-sensitive precautions and use
suitable tools when cleaning circuit boards and
assemblies that are sensitive to electrostatic
discharge
