We declare that we meet the EN 62479 standard with respect to the limiting value for low
powers less than 20 mW. Therefore, the product fundamentally corresponds to the Euro-
pean limiting values for high-frequency radiation.

4.5 Derating

The following figure shows the maximum permissible current (I) that can flow into the
product as a function of the surrounding air temperature (T).
Please note the derating for use of the product. The surrounding air temperature and the
current affect the product's heat generation.
The derating curve was created with the following conditions of use: "without air move-
ment and with 0.5 m/s air movement" and "mounting on wall with poor heat conductivity."
The real conditions of use may lead to better heat dissipation from the product, e.g. due
to greater air movement or better dissipation of heat to the mounting wall. The product
provides measured values for temperature and current, which you can display with
WAGO Webserver I/O Field or read out via OPC UA.
The following figure shows the maximum permissible current (I) that can flow into the
product as a function of the surrounding air temperature (T).
Also note the derating curve for the individual contacts (pins) of the L-coded connections
X31 and X32. The following figure shows the maximum permissible current (I) that can
flow through the contact (pin) as a function of the ambient temperature (T).
