6-1 Inspection and Maintenance „ Daily Inspection and Periodic Inspection 6 Inspection and Maintenance *1. The life of the capacitor depends on ambient temperatures. Refer to "Product Life Curve" (App-17). *2. Clean the Inverter periodically. Accumulated dust in or on the cooling fan or heat sink can cause the Inverter to overheat. 6-3 Inspection part Inspection item Inspection point Inspection period Inspection method Criteria Standard replacement period Meter Daily Periodic General Ambient environment Entire device Power supply voltage Check ambient temperature, as well as checking for humidity, dust, hazardous gases, oil mist, etc. Check that there are no abnormal vibrations or sounds.
Check that the main circuit voltage is normal. 3 3 3 Monitoring, visual inspection Visual or acoustic inspection Voltage measurement between terminals R/L1, S/L2 and T/L3 on the Inverter terminal block. Ambient temperature -10°C to +40°C With no freezing Ambient humidity 20% to 90% With no condensation The following conditions must be satisfied: (200-V class) 200 to 240 V 50/60 Hz (400-V class) 380 to 480 V 50/60 Hz Thermometer Hygrometer Tester
