Ambient and environmental conditions
When you plan your project, you should make allowances for:
● The climatic and mechanical environmental conditions specified in the specifications
provided by your operating instructions.
● Avoid extreme ambient conditions as far as possible. Protect your PC from dust,
moisture, and heat.
● The device has been designed for usage in a normal industrial environment according to
IEC 60721-3-3 (pollutant class 3C2 for chemical influence, 3S2 for sand and dust). PC
may not be used in severe operating environments, for example locations with acidic
vapors or gasses, without additional protective measures (such as the provision of clean
air).
● Keep the PC out of direct sunlight.
● Mount the PC as safely as possible to prevent danger (for example, of falling over).
● The device conforms to protection class IP 30 at the front panel.
● The clearance in the area of the ventilation slots must be at least 50 mm, so that the PC
is sufficiently ventilated.
● Do not cover the vent slots of the device.
● The device fulfills the requirements for a fire enclosure according to EN 60950-1. It can
be installed without additional fire protection.
● The connected or added peripherals must not introduce a counter emf greater than 0.5 V
into the device.
WARNING
Failure to comply with these requirements for system installation shall render approvals
to UL 60950-1, EN 60950-1 void and leads to the risk of overheating and injury!
