Cleaning
￭ Cleaning the interior of the cabinet
WARNING!
Read the safety instructions given in Safety instructions for ACS880
multidrive cabinets and modules (3AUA0000102301 [English]). If you
ignore them, injury or death, or damage to the equipment can occur.
WARNING!
Use a vacuum cleaner with an antistatic hose and nozzle, and wear a grounding
wristband. Otherwise an electrostatic charge might build up and damage the circuit
boards.
1.
Stop the drive and do the steps in section Electrical safety precautions (page 144) before
you start the work.
2. Open the cabinet door.
3. Clean the interior of the cabinet. Use a vacuum cleaner and a soft brush.
4. Clean the air inlets of the fans and air outlets of the modules (top).
5. Clean the air inlet gratings (if any) on the door.
6. Close the door.
￭ Cleaning the heatsink
The drive module heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean. When necessary, clean
the heatsink as follows.
WARNING!
Read the safety instructions given in Safety instructions for ACS880
multidrive cabinets and modules (3AUA0000102301 [English]). If you
ignore them, injury or death, or damage to the equipment can occur.
WARNING!
Use a vacuum cleaner with antistatic hose and nozzle. Using a normal vacuum
cleaner creates static discharges which can damage circuit boards.
1.
Stop the drive and do the steps in section Electrical safety precautions (page 144) before
you start the work.
2. Remove the drive module from the cabinet.
3. Remove the module cooling fan(s). See the separate instructions.
4. Blow dry, clean and oil-free compressed air from bottom to top and simultaneously use
a vacuum cleaner at the air outlet to trap the dust.
Note:
If there is a risk of dust entering adjoining equipment, perform the cleaning in another
room.
5. Reinstall the cooling fan.
