Types of installation
The devices can be installed in the following ways:
● Installation on a 35 mm DIN rail
● Installation on a SIMATIC S7-300 standard rail
● Wall mounting
If a device is operated in an ambient temperature between 50 ℃ and 75 ℃, the temperature
of the device housing may be higher than 70 °C. The device must therefore be installed so that
it is only accessible to service personnel or users that are aware of the reason for restricted
access and the required safety measures at an ambient temperature of 50 ℃ to 75 ℃.
Installation clearance
Keep to the minimum clearances so that the convection ventilation of the device is not blocked.
● Below at least 10 cm
● Above at least 10 cm
