Information
4.4 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.
WARNING
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.
WARNING
See Pr 05 on page 21 (Drive configuration) for terminal set-up diagrams and details.

Operation of contact
OPEN
AC supply removed from drive
AC supply applied to drive with drive in tripped condition
CLOSED
AC supply applied to drive with drive in a 'ready to run' or
'running' condition (not tripped)
Provide fuse or other over-current protection in status relay circuit.
