13.2.2 Ethernet communication interface
This interface is located on the module in the form of a 8-pin RJ45 socket on the bottom side of
the housing.
Plug the Ethernet-connector onto the RJ45 socket labeled "RJ45 Ethernet" until it snaps in.
•
Please make sure that the length of the line to the adjacent Ethernet participants does not fall
•
below 0.6 m.
13.2.3 Line routing, shield and measures to combat interference voltage
This chapter deals with line routing in the case of bus, signal and power supply lines, with the aim
of ensuring an EMC-compliant design of your system.
13.2.4 General information on line routing
- Inside and outside of cabinets
In order to achieve EMC-compliant routing of the lines, it is advisable to split the lines into the fol-
lowing line groups and to lay these groups separately.
Group A:
• shielded bus and data lines (e. g. for RS232C and printers etc.)
• shielded analogue lines
• unshielded lines for DC voltages 60 V
• unshielded lines for AC voltage 25 V
• coaxial lines for monitors
Group B:
• unshielded lines for DC voltages 60 V and 400 V
• unshielded lines for AC voltage 24 V and 400 V
Group C:
• unshielded lines for DC voltages > 400 V
The table below allows you to read off the conditions for laying the line groups on the basis of the
combination of the individual groups.

Table 3: Line laying instructions as a function of the combination of line groups
1) Lines may be laid in common bunches or cable ducts.
2) Lines must be laid in separate bunches or cable ducts (without minimum clearance).
3) Lines must be laid in separate bunches or cable ducts inside cabinets but on separate cable
racks with at least 10 cm clearance outside of cabinets but inside buildings.
13.2.4.1 Shielding of lines
Shielding is intended to weaken (attenuate) magnetic, electrical or electromagnetic interference
fields.
Interference currents on cable shields are discharged to earth via the shielding bus which is con-
nected conductively to the chassis or housing. A low-impedance connection to the PE wire is
particularly important in order to prevent these interference currents themselves becoming an
interference source.
