+ Installing the Rack PC
The Rack PC is particularly suitable for horizontal fitting in consoles, switch boards and 19” rack
systems.
The Rack PC with AC power supply meets the requirements for a fire enclosure to EN60950. it can
therefore be fitted without an additional fire enclosure.
The Rack PC with DC power supply does not fulfil the power supply connection requirements for a
fire enclosure. Therefore, the device has to be installed in a fire enclosure in such a way that the
device front can remain accessible as it fulfills the fire enclosure requirements according to UL 508.
