UNIGATE fieldbus gateway UNIGATE CL - ProfibusDP V. 2.3
17.6.10
13.2.1.2 Equipotential bonding connection
The connection to the potential equalization automatically takes place it is put on the DIN-rail.
13.2.2 ProfibusDP communication interface
13.2.2.1 Bus line with copper cable
This interface is located on the module in the form of a 9-pin D-SUB socket on the front side of
the housing.
•
Plug the Profibus connector onto the SUB-D socket labelled "ProfibusDP".
•
Firmly screw the securing screws of the plug connector tight using a screwdriver.
•
If the module is located at the start or end of the Profibus line, you must connect the bus termi-
nating resistor integrated in the gateway. In order to do this, slide the slide switch to the posi-
tion labelled ...on...
•
If the module is not located at the start or at the end, you must set the slide switch to position
"off".
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 ProfibusDP, 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.
