1)
The operating temperature of SCALANCE X204RNA is independent of the mounting position.
2)
Consider mounting position of the SCALANCE X204RNA EEC
If you install the SCALANCE X204RNA EEC in a vertical mounting position, an ambient temperature of max. +40 °C is permitted.
If you install the SCALANCE X204RNA EEC in a vertical mounting position at > 40 °C, the device approvals will no longer be valid.
