DC Bus Output Wiring
The length of the DC bus connections between the AFE and the drive or drives
must be minimized to keep the bus inductance low for reliable system operation.
For more information, see Drives in Common Bus Configurations, publication

(1) Maximum/minimum sizes that the terminals will accept - these are not recommendations.
(2) Do not exceed maximum wire size. Parallel connections may be required.
(3) These connections are bus bar type terminations and require the use of lug type connectors.
(4) Apply counter torque to the nut on the other side of terminations when tightening or loosening the terminal bolt to avoid damage to the terminal.
