Danger to the module!
All ESD protection measures must be observed when using the mo

A module is inserted along the rail in the subrack and fastened in place with
the two knurled screws on the front panel.
A good coupling of the module with the subrack guarantees high mechan
ical resistance and contact stability as well as increased insensitivity to ex
ternal electrical interference.
The knurled screws on the front panels must be fastened with max. 0.5 Nm.
. Dummy slots in a subrack must be covered with dummy covers, since
otherwise the air circulation will be impaired.
