NOTE
Pre-assembled cables with open cable end at one end:
Information about pin, signal and wire color assignments can be found in the appendix,
see "Signal assignment of cables with open cable end at one end", page 74.
NOTICE
Faults during operation and device or system defects!
Incorrect wiring may result in operational faults and defects.
■
Follow the wiring notes precisely.
The electrical connection of the device is configured as a cable with a D-Sub HD male
connector.
The enclosure rating stated in the technical data is achieved only with a screwed plug
connector. If an extension cable is used, a corresponding rubber seal (SICK accessory)
must be fitted between the two plug connectors.
Shielding requirements
■
To ensure a fault-free data transmission, an effective and comprehensive shielding
solution must be implemented.
■
Apply a cable shield at each end, i.e. in the control cabinet and at the device. The
cable shield of the connecting cable is connected to the housing of the D-Sub plug
connector. After plugging in and fixing the plug connector, the screen is connected
to the device housing over a large area.
■
The cable shield in the control cabinet must be connected over a large surface to
the ground potential on the potential equalization conductor.
■
Take appropriate measures (e.g. earthing method) to prevent equipotential bond‐
ing currents from flowing through the cable shield.
■
During installation, pay attention to the different cable groups. The cables are
grouped into the following four groups according to their sensitivity to interference
or radiated emissions:
°
Group 1: cables very sensitive to interference, such as analog measuring
cables
°
Group 2: cables sensitive to interference, such as device cables, communica‐
tion signals, bus signals
°
Group 3: cables that are a source of interference, such as control cables for
inductive loads and motor brakes
°
Group 4: cables that are a powerful source of interference, such as out‐
put cables from frequency inverters, welding system power supplies, power
cables
b
Cables in groups 1, 2 and 3, 4 must be crossed at right angles (see
figure 19).
b
Route the cables in groups 1, 2 and 3, 4 in different cable channels or
use metallic separators (see figure 20 and see figure 21). This applies partic‐
ularly if cables of devices with a high level of radiated emission, such as
frequency converters, are laid parallel to device cables.
