10 I/O specification
The control circuits are isolated from the power circuits in the drive by basic insulation (single insulation) only. The installer must ensure
that the external control circuits are insulated from human contact by at least one layer of insulation (supplementary insulation) rated for
use at the AC supply voltage.
If the control circuits are to be connected to other circuits classified as Safety Extra Low Voltage (SELV) (e.g. to personal computer), an
additional isolating barrier must be included in order to maintain the SELV classification.
