Passivation Layer
When lithium batteries (lithium/thionyl chloride) are used, the battery may not
function immediately if the battery has been stored a long time and has developed
a passivation layer. For remedies, refer to Removal of the Passivation Layer of the
Backup Battery.

Mechanical and Climatic Environmental Conditions
Operating Conditions
The modules have been tested in a device that likewise complies with the
standards indicated below. If the modules are operated in a device that does not
comply with these standards, adherence to the values cannot be guaranteed.
Usage with Additional Measures Only
The CPU 41x-2 PCI must not be used without additional measures being taken
•
At locations subject to a high degree of ionizing radiation
•
At locations with harsh operating conditions; for example, due to
-
Dust
-
Corrosive vapors or gases
-
Strong electrical or magnetic fields
•
In facilities requiring special monitoring, such as
-
Lifts
-
Electrical systems in particularly hazardous areas
An additional measure might be operation in an enclosure or cabinet.
Mechanical Environmental Conditions
The SIMATIC Box PC 627 is designed to meet stringent requirements for
mechanical environmental conditions (vibration test with 1 g constant load at a
frequency of 58 to 500 Hz). The CPU 41x-2 PCI complies with these requirements
when operated in a SIMATIC Box PC 627.
If the CPU 41x-2 PCI is installed in other PCs with longer slots than 3/4 PCI and
greater mechanical stresses, you must mechanically secure the back end of the
PCB.
