Flexible cable has better flexibility. Since cable may contact high-temperature
device during use, it’s better to use copper core or heat-proof flexible cable or
fire-retardant cable. Braking unit and inverter should be as close as possible to each other,
and it’s better to keep their distance no more than 2 m, otherwise DC side cable should be
twisted and sheathed with magnetic ring to reduce radiation and inductance.
The length of the cable between inverter and braking unit should be less than 2m.
The length of the cable between braking unit and braking resistor can be more than 2m.
