(8) General precautions
CAUTION
Periodically back up the programs, tool data and parameters to avoid potential data loss. Also, back up those data
before maintenance and inspections.
When replacing the battery on the controller side, the machining programs, tool data and parameters should be
backed up with the input/output device beforehand. In case the memory is damaged in replacing the batteries,
reload all the data backed up before replacing the battery.
The electrolytic capacitor’s capacity will drop due to deterioration. To prevent secondary damage due to
capacitor’s faults, Mitsubishi recommends the electrolytic capacitor to be replaced approx. every five years even
when used in a normal environment. Contact the Service Center or Service Station for replacements.
Do not perform a megger test (insulation resistance measurement) during inspection.
Do not replace parts or devices while the power is ON.
Do not short-circuit, charge, overheat, incinerate or disassemble the battery.
There may be a unit filled with substitute Freon in the heat radiating fins of the 37kW or smaller unit. Be careful not
to break the heat radiating fins during maintenance or replacement.
CAUTION
Take the batteries and backlights for LCD, etc., off from the controller, drive unit and motor, and dispose of them
as general industrial wastes.
Do not alter or disassemble controller, drive unit, or motor.
Collect and dispose of the spent batteries and the backlights for LCD according to the local laws.
To explain the details, drawings given in the instruction manual, etc., may show the unit with the cover or safety partition
removed. When operating the product, always place the cover or partitions back to their original position, and operate as
indicated in the instruction manual, etc.
