Environmental Conditions
Temperatures
Type test, in operation
(in compliance with IEC 60068-2-1 and
IEC 60068-2-2, test Ad for 16 h and test Bd for 16 h)
-25 °C to +85 °C

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