7.2 Installation External Wiring
Customer-supplied medium voltage cables enter an access plate in the top or bottom.
Customer-supplied low-voltage cables (#8 - #22 AWG) for the control enter an access plate
in the top or bottom. Refer to the project drawings for exact locations.
The input and output medium voltage terminals (L1, L2, L3 and T1, T2, T3) are offset from
one another and can adapt to top or bottom cable termination.

The actual cross-section of input wire is not necessarily the maximum vaule. When input and output voltages are same,

the cross-section of the input wire and the output wire should be kept same.
Note
Individual conductor breakdown for three-conductor single-core cables
The SINAMICS PERFECT HARMONY GH180 drive design is best accommodated for single-
conductor single-core medium voltage cables.
Note
Cable length rules
For long length cable application, the length of cable cannot be longer than 2 km using 21-cell
system. If the cable length exceeds 2 km, the 24-cell system must be used.
