Inspection and Maintenance
General Precautions
• Always keep the Inverter and area clean to prevent dust from entering.
• Take utmost care not to have the wires disconnected or connected wrongly. Tightly fix the
terminals and connectors.
• Do not expose the electronic device to humidity, oil, dust and/or iron powder or shavings. Doing so
may damage the insulation and result in an accident.
• Do not pull on the cables in connecting/disconnecting the connectors (cooling fan and control PCB
cables). Doing so may result in fire or injury due to cable damage.
Inspection Item
• Daily inspection
• Periodic inspection (about every year)
• Insulation resistance test (about every two years)
• Megger test
Short the terminals as below to conduct the test.
• Make sure that the resistance between the main circuit terminal and ground is 5 M
Ω
or more at 500
V DC megger.
• Do not conduct a withstand voltage test on any part of the Inverter.
Doing so may result in the deterioration of parts.
* To shorten non-operation time, we recommend always keeping a spare Inverter ready.
