4) For storage in the product packaging.
Note
Remove the transport protective foil and packaging material before installing the components.
4.1.2.2 Operating conditions
The components of the SINUMERIK 840D sl system are intended for a weatherproof, xed
location. The documented
environmental conditions apply to the climate in the immediate vicinity of the units and to the
entry of the cooling air. They exceed the requirements according to EN 60204-1, EN 61800-2,
EN 61131-2 and IEC 62477-1.
NOTICE
Damage to components by coolants and lubricants
The SINUMERIK operator components have been designed for industrial use, particularly on
machine tools and production machines. This also takes into account the use of commercially
available coolants and lubricants. The use of aggressive compounds and additives can damage
components and result in their failure.
Contact between the operator components and coolants and lubricants should be avoided as
far as possible, as resistance to all coolants and lubricants cannot be guaranteed.
