Making Connections

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.
WARNING
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.
