MAINTENANCE AND INSPECTION
This shows items that must be maintained or inspected daily or periodically to properly use the product in optimal condition at
all times.
• In order to prevent problems such as short circuits or bad insulation as a result of issues relating to service
life or deterioration, ensure that the power supply is turned OFF when the product is not being operated for
a long period of time.
• From the perspective of preventive maintenance, regular replacement of parts with a finite service life is
recommended. If an ambient temperature is 40°, a guideline is to replace the power supply module every 5
years, and the fan module every 5 to 10 years.
