protective measures (such as the provision of clean air), the SIMOTION P320-4 computing
unit cannot be used in places with severe operating environments, for example, locations
with corrosive vapors or gases.
● The clearance in the area of the ventilation slots must be at least 100 mm, so that the

of an operating area with restricted access (e.g. a locked control cabinet, console or server
room).
● Always observe the mounting positions permitted for this device.
● The connected or installed I/O should not generate a reverse voltage greater than 0.5 V in
the device.
