3.4 Ambient and environmental conditions
When you plan your project, take note of the following points:
●
Observe the climatic and mechanical environmental conditions specified in the technical
specifications of your operating instructions.
● This device was designed for use in a normal industrial environment. Without additional
protective measures (such as the provision of clean air), SIMATIC Box PCs may not be
operated in harsh environments that are subject to caustic vapors or gases.
● At least 100 mm space should be left free around the ventilation slots, in order that the
PC receives sufficient ventilation.
● Do not cover the vent slots of the device.
● The device together with its AC power supply fulfils the requirements for fire protected
enclosures according to EN 60950-1. Therefore it can be installed without any additional
fire protective covering.
● The device with DC power supply does not fulfill the requirements according to
EN 60950-1 in the power supply unit area. The device must therefore be installed in such
a ways is part of an operating area with restricted access (e.g. a locked switchgear
cabinet, control panel or server room).
● Always observe the mounting positions permitted for this device.
● The connected or built-in peripherals should not introduce negative field voltage in excess
of 0.5 V into the device.
WARNING
Failure to adhere to these conditions when mounting the system voids the approvals
based on UL 60950-1, UL 508 and EN 60950-1!
