Technical data

1)
An external 24Vdc SELV/PELV power supply must be used. This must not
be connected to any other external HW which is not related to functional
safety. It must limit the output voltage under all fault conditions to < 60Vdc.
The Emotron OSTO_100 option board input is safely designed to
withstand input voltage up to 60Vdc.
Note!
Do NOT use the generic
24Vdc output available on AC drive control board on Emotron AC drive as
this is the system voltage used both for internal and external/auxiliary
connected hardware. Further, this generic 24Vdc output is not isolated and
cascading this signal to multiple drives with possible potential difference
may cause damage to the output.
