11.3.10 Precautions for external regenerative resistor use
■
The place where corrosive gas has occurred, and when there is much dust, insulated
degradation, corrosion, etc. may arise. Therefore be careful of an attachment place.
■
External regeneration resistor should be placed by keeping enough distance from the other
parts so as not to be affected by the other parts-generated heat.
■
Must wiring by twisted lines to external regenerative resistor. Wiring length keeps 5 m or less,
and aims as short as it can.
■
Wiring should keep no contact with regenerative resister, and using flame-retardant cable or
giving flame-retardant by silicon tube.
