Connecting Cable
Since all brake unit and braking resistors work at a high voltage (>400VDC) in a
non-continuous working status, please select applicable cable. See Table 11-2 for
specifications of main circuit cable, and take the cable which meets the insulation and
cross-section requirements.

Soft cable possesses a better flexibility, so copper cable, soft heat-proof cable or
flame-proof cable is suggested because the cable may contact the equipment with high
temperature.The distance between braking unit and inverter shall within 2m. Otherwise, the
cable on DC side shall be twisted and shielded with magnetic ring to reduce radiation and
induction.
