K-System – Isolated Barriers
Mounting and Installation
Mounting Conditions for Operating the Device at Higher Ambient Temperature
Certain devices with a maximum allowable ambient temperature of 60 °C (140 °F)
can be operated at ambient temperatures up to 70 °C (158 °F) if mounted horizontally.
These devices have a corresponding reference to this manual in the datasheet.
Mounting the Isolated Barriers with Separation Distance
Mount the device on the DIN mounting rail. Observe the specified minimum
separation distance. See following figures.
• KC devices with 12.5 mm housing width, housing type A*: min. 6 mm
• KF devices with 20 mm housing width, housing type B*: min. 10 mm
• KF devices with 40 mm housing width, housing type C*: min. 15 mm

Caution!
Device failure due to overlooking heat dissipation
Overlooking heat dissipation can compromise the function and the electrical safety
of the device.
• Mount the device on the DIN mounting rail in a horizontal mounting position.
• Mount the device on the DIN mounting rail according to the specified minimum
separation distance.
• Do not operate devices without this reference in the datasheet at an ambient temperature
up to 70 °C (158 °F).
