Cleaning
Although the electrical cabinet is constructed
to shut off external air, foreign particles such
as dust and dirt may enter the cabinet when
the door is open.
Accumulation of foreign particles on the
printed circuit boards or other electronic com-
ponents could cause machine malfunction.
Clean the inside of the electrical cabinet regu-
larly.
Remove dust inside electrical cabinet with a
vacuum cleaner. Do not use compressed air
to clean the electrical cabinet.
Never touch circuit boards or parts around
the connector. Also avoid hitting these parts
with the vacuum.
We recommend that the electrical cabinet is
cleaned every 1000 operating hours.
