KATANA S610M Inverter Specialized for Elevator Manual
2. Cleaning
①
Keep the inverter clean;
②
Clear dust on the surface effectively to prevent dust from entering inside the inverter, especially the metal
dust;
②
Clear greasy dirt off the cooling fan effectively.
9.2 Periodical Maintenance
User can make a regular check every 3-6 months or by even shorter time according to the operation conditions, to
prevent the inverter from breakdown, and to guarantee its high performance for a longer time. Please check the
following:
1
．
Check if the working ambient temperature and humidity meet the standard requirements.
2
．
Make a thorough clean for the dust on the surface of PCB, wind channel, heat-sink, which is better to be
cleaned by dust collector.
3
．
Please check if the screws on the wiring terminals are fastened firmly. If they are loose, please fasten them
by the screwdriver; check if connectors or flat cables are loose or attached with any foreign matter.
4
．
Check if power cable and control cable are damaged, especially if there are any cut scratches in the wire
jacket which contacts with the metal surface; check if the insulation binder of the power cable nose peels off.
5
．
Check if poor connection of the main circuit terminal happens, and if the contact point of the copper platoon
is overheated.
6
．
Check if the controller is damaged, transformed, or corroded.
7
．
Check if there is any leakage, color change, crack or expansion of electrolytic capacitor.
8
．
Please check insulation of the main circuit.
Attention
：
Please detach the main circuit wire from the vector control unit when measuring
insulation resistance by megameter (DC, 500V). Never measure control circuit insulation by insulation
resistor.
9
．
Please check insulation of the motor.
Attention
：
Be sure to inspect the motor alone after the wire between the motor and the inverter is
completely disconnected. Otherwise, the inverter may be damaged.
