WARNING
Risk of injury due to insufficient training!
An appropriate training is necessary for the following maintenance steps to avoid inju-
ries.
• This maintenance step may only be carried out by trained and authorized specialist staff.
• Observe warnings and maintenance instructions at the beginning of this chapter!
Figure 6-8
• Switch off the machine and disconnect the mains plug. Remove the screws of the side panels and the
grille at the rear. Remove side panels (lift up and to the side). Remove louvre (remove downwards and
to the back).
• Use only compressed air free of water and oil. Do not blow on electronic components directly. The ma-
chine fans may over-rev due to the compressed air and thus become damaged. Therefore, use a
screwdriver to block the machine fan mechanically.
Figure 6-9
• Blow out the areas in front of the inverter from the side.
Follow official regulations on disposal!
• After cleaning, remove any mechanical blockages from the fans, close the machine in reverse order
and check according to applicable regulations.
