If the basic board
APCI-7xxx-3
is used with optically isolated modules and non
isolated modules, then the safety built by the creeping distance of 3.2 mm is not
ensured for the non isolated modules.
The use of the board in a PC could change the PC features regarding noise
emission and immunity. Increased noise emission or decreased noise immunity
could result in the system not being conform anymore.
Check the shielding capacity of the PC housing and cable prior to putting the
device into operation.
The use of the board includes observing all advises given in this manual and in the
safety leaflet.

MXxxx-G:
E.g. PM232-G: Module for the operating mode RS 232 with option G (optical
isolation)
MXTTY: Module for 20 mA constant loop. As standard it is optically isolated.
