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 (
).
b
Route the cables in groups 1, 2 and 3, 4 in different cable channels or
use metallic separators (
). 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.
