Special conditions for safe use of the BusAdapter

Introduction
The I/O system in which the BusAdapters are to be used must be installed in a suitable
enclosure which ensures at least IP 54 degree of protection according to EN 60529.
Use a safety enclosure that meets the requirements regarding spread of fire and exhibits an
appropriate strength according to UL61010-1 and UL61010-2-201.
The I/O system is intended only for weather-protected, dry and stationary use.
Safety information
Enclosure and cables
The device is intended for installation in an enclosure / control cabinet. The internal operating
temperature of the enclosure / control cabinet corresponds to the maximum permissible
ambient temperature of the module.
Cables must be used whose maximum permissible operating temperature is at least 30 °C
above the maximum permissible ambient temperature.
Ambient temperature of the device
The temperature of the device housing can be higher than 70 °C if the device is operated at
an ambient temperature of more than 50 °C. The device must therefore be installed so that it
is only accessible to service technicians or users who are aware of the reason for the restricted
access and the necessary safety measures at an ambient temperature of over 50 °C.
