Load conditions for the non-modular devices: With
temperatures above 55 °C, no more than 50 % of
the binary inputs and relay outputs per printed circuit
board assembly are allowed to be continuously active.
Readability of the display may be impaired below
-10 °C and above +55 °C.

≤ 75 % relative humidity on the annual average
Up to 93 % relative humidity on 56 days a year
Transient condensation is permissible.
Arrange the devices so that they are not exposed to
direct sunlight or extreme temperature changes. This
will prevent condensation in the device.
