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-circuit 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.
