CAUTION
•
The heat sink and dynamic braking resistor are heated to high temperatures, so never touch them.
Failure to observe this could lead to burns.
•
Do not block the inverter’s ventilation holes.
Failure to observe this could lead to fires.
•
The inverter operation can easily be set from low speeds to high speeds, so confirm that the operation
is within the tolerable range for the motor or machine before making settings.
Failure to do so could lead to injuries.
•
Prepare holding brakes when necessary. Holding is not possible with the inverter’s brake functions.
Failure to do so could lead to injuries.
•
Confirm the operation of the motor as a single unit before operating the machine.
Failure to do so could lead to injuries or machine damage due to unforeseen movements.
•
Always prepare a safety backup device so that the machine is not placed in a hazardous situation
when an error occurs in the inverter.
Failure to do so could lead to injuries or machine damage.
4. Maintenance, Inspection and Part Replacement
DANGER
•
Always wait at least 20 minutes after turning the input power OFF before starting inspections. 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 "CHARGE" LED on the unit 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.
(Check with the "CHARGE" LED if the unit is not provided with the L– terminal.)
Failure to observe this could lead to electrical 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 electrical 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 electrical shocks and injuries.
•
Do no use parts other than those designated for the replacement parts.
Failure to observe this could lead to fires.
CAUTION
•
Vacuum the inverter with a vacuum cleaner to clean it. Do not use organic solvents.
Failure to observe this could lead to fires or damage.
