Inspection and Maintenance

H Daily Inspection
Check the following items while the system is operating.
• No abnormal noise or vibration in the motor
• No abnormal heat generation
• Output current monitor display is not a higher value than normal
• Cooling fan installed in Inverter is operating normally (models with fans only)
H Periodic Inspection
Check the following items when performing periodic maintenance.
Always wait at least one minute after the power supply has been turned OFF and all the LED indicators
have turned OFF before performing maintenance. Touching the terminals immediately after the power
is turned OFF may result in electric shock.
• No looseness in terminal screws
• No electroconductive dust or oil mist attached to terminal block or the Inverter's internal parts
• No looseness in Inverter mounting screws
• No accumulation of dirt or dust on cooling fin (heat sink)
• No dust accumulated in the ventilation holes
• No abnormality in external appearance
• Cooling fan in control panel is operating normally
(Check that there is no abnormal noise or vibration, and that the total ON time has not exceeded the
specified value.)
H Periodic Maintenance of Components
The Inverter is constructed from many components, the normal operation of which is required for the
essential functionality of the Inverter. Maintenance is required for some of the electronic components
depending on the operating conditions. To enable the Inverter to operate normally for a long time, peri-
odic inspection and component replacement must be performed to suit the service life of these compo-
nents.
(Source: "Instructions for Periodic Inspection of General Purpose Inverter" (JEMA))
The guidelines for periodic inspection depend on the Inverter's installation environment and operating
conditions.
The maintenance periods for the Inverter are listed below. Use this to determine when periodic mainte-
nance is required.
The guidelines for periodic maintenance are as follows:
• Cooling fan: 2 to 3 years
• Electrolytic capacitor: 10 years
• Fuse: 10 years
These guidelines are applicable for an operating environment in which the ambient temperature is
40°C, the load rate is 80%, the operating time is 8 hours per day, and the product is installed according to
the instructions in the manual.
