84 Mounting
contact must not form a galvanic cell with the material of the carrier rail
which generates a differential voltage above 0.5 V (saline solution of 0.3 %
at 20°C).
•
The carrier rail must optimally support the EMC measures integrated into
the system and the shielding of the I/O module connections.
•
A sufficiently stable carrier rail should be selected and, if necessary,
several mounting points (every 20 cm) should be used in order to prevent
bending and twisting (torsion).
•
The geometry of the carrier rail must not be altered in order to secure the
safe hold of the components. In particular, when shortening or mounting the
carrier rail, it must not be crushed or bent.
•
The base of the I/O components extends into the profile of the carrier rail.
For carrier rails with a height of 7.5 mm, mounting points are to be riveted
under the node in the carrier rail (slotted head captive screws or blind
rivets).
•
The medal springs on the bottom of the housing must have low-impedance
contact with the DIN rail (wide contact surface is possible).
