For the sizes of wires used for wiring, refer to section 12.6.
The regenerative option will cause a temperature rise of 100 relative to the ambient temperature. Fully
examine heat dissipation, installation position, used cables, etc. before installing the option. For wiring, use
flame-resistant wire and keep them clear of the regenerative option body. Always use twisted cables of max.
5m length for connection with the driver.
