14.3 Precautions for maintenance and inspection
WARNING
Make sure to remove the input power while performing maintenance.
Make sure to perform maintenance after checking the DC link capacitor has discharged. The bus
capacitors in the inverter main circuit can still be charged even after the power is turned off. Check
the voltage between terminal P or P1 and N using a tester before proceeding.
GS inverter has ESD (Electrostatic Discharge) sensitive components. Take protective measures
against ESD before touching them for inspection or installation.
Do not change any inner parts and connectors. Never modify the inverter.
14.4 Check points
Daily inspections
Proper installation environment
Cooling system fault
Unusual vibration and noise
Unusual overheating and discoloration
Periodic inspection
Screws and bolts may become loose due to vibration, temperature changes, etc.
Check that they are tightened securely and retighten as necessary.
Alien substances are clogged in the cooling system.
Clean it using the air.
Check the rotating condition of the cooling fan, the condition of capacitors and the connections with
the magnetic contactor.
Replace them if there are any abnormalities.
14.5 Part replacements
The inverter consists of many electronic parts such as semiconductor devices. The following parts
may deteriorate with age because of their structures or physical characteristics, leading to reduced
performance or failure of the inverter. For preventive maintenance, the parts must be changed
periodically. The parts replacement guidelines are indicated in the following table. Lamps and other
short-life parts must also be changed during periodic inspection.
