Ambient and environmental conditions

Observe environmental conditions
If the following conditions for system installation are not observed, approvals in accordance
with UL 60950-1 and EN 60950-1 are rendered void and there is a risk of overheating and
personal injury.
When you plan your project, you should make allowances for:
● Climatic and mechanical environmental conditions defined in the "General technical data"
chapter of the operating instructions.
● Avoid extreme ambient conditions as far as possible. Protect your device against dust,
moisture and heat.
● This device was designed for use in a normal industrial environment. SIMATIC Rack PCs
may not be operated in severe environments which are subject to caustic vapors or
gases without taking additional protective measures (such as the provision of clean air.)
● Do not expose the device to direct sunlight.
● Install the device in such a way that it poses no danger, for example, by falling over.
● Ensure that the installation opening for the device is splash-proof in areas which may be
subject to splash water.
● Ensure there is sufficient volume for air circulation and heat transport so that the device is
adequately ventilated.
● Do not cover the ventilation slots of the enclosure. A clearance of at least 5 cm must be
maintained at the back of the device, depending on the cabling.
● Do not allow the maximum air intake temperature directly in front of the air intake opening
to exceed 35° C. The maximum air intake temperature must be taken into consideration
in particular when sizing enclosed control cabinets.
● The device meets requirements for fire protection housings to EN 60950-1 and can be
installed without additional fire protection enclosure.
● The connected or built-in peripherals should not introduce a counter emf in excess of
0.5 V into the device.
