Warning
The control circuits are isolated from the power circuits in
the Drive by basic insulation only, as specified in IEC664–1.
The installer must ensure that the external control circuits
are insulated from human contact by at least one layer of
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) (eg. to a
personal computer), an additional isolating barrier must be
included in order to maintain the SELV classification.
