CHAPTER-8: MAINTENANCE, INSPECTION AND PART REPLACEMENT
DANGER
Always wait at least 20 minutes after turning the input power OFF before starting inspection.
Wait at least 20 minutes after turning the input power OFF before starting work. Make sure that
the displays on the operation panel have gone out before removing the front cover.
Remove the front cover, and confirm that the “DC BUS CHARGE LED” on bleeder board has
gone out. Also check that the voltage between terminals L+1 or L+2 and L– is 15V or less before
starting the inspections.
Failure to observe this could lead to electric shocks.
Maintenance, inspections and part replacement must be done by a designated person.
(Remove all metal accessories such as watches, bracelets, etc., before starting the work.)
(Always use an insulation measure tool.)
Failure to observe this could lead to electric shocks and injuries.
Always turn the power OFF before inspecting the motor or machine. A potential is applied on the
motor terminal even when the motor is stopped.
Failure to do so could lead to electric shocks and injuries.
Do not use parts other than those designated for the replacement parts.
Contact your AC DRIVE dealer for replacement parts.
Failure to observe this could lead to fires.
Never modify the product.
Failure to observe this could lead to electric shocks or injuries or product failure.
CAUTION
