1.1 General instructions
WARNING
Before starting installation or maintenance work,
switch off the following:
• the compressed air supply
• the operating voltage on the field bus node
(pins 1 and 2)
• the power supply to the
CP output modules
You thereby avoid:
– uncontrolled movements of loose tubing.
– unintentional movements of the connected
actuators.
– undefined switching states of the electronic
components.
CAUTION
The node of the CP system contains electrostatically
vulnerable components.
• Do not, therefore, touch any components.
• Please observe the regulations for dealing
with electrostatically vulnerable components.
In this way you will avoid irreparable damage to the
electronic components on the node.
General information on the installation of the CP as-
semblies can be found in the manual "CP system".

1.2 Setting the DIL switches
The DIL (dual in-line) switch is situated under the cover
of the field bus node.
WARNING
• Before commissioning:
Set switch 4 to the position relevant to your
controller (see manufacturer-specific addressing).
• During operation:
Do not modify the setting of the DIL switch.
In this way you can avoid undesired reactions of the
connected actuators.

terminal. One of these connections is intended for the
incoming cable, the other for the continuing field bus
cable.

Different INTERBUS modules and therefore different
screening/shielding and connection methods must be
used, depending on your application.
Possible screening/shielding variants:Screening/
shielding
variants – Floating structure:
(interference suppression via RC network or con-
nection to optical-fibre waveguide)
– Non-floating structure:
(interference suppression via earthing on both sides)
Possible connection variants:Connection
variants – Remote bus (floating/non-floating)
– Remote bus with optical-fibre waveguide
– Installation remote bus (non-floating)
Please observe the following differences between the
remote bus and the installation remote bus.

1.3.1 Floating structure
Floating structures should be used preferably for parts
of a system which are situated at great distances from
each other, and where different earth potentials and in-
terference are to be expected as a result of equalizing
currents or earthing loops.
With floating structures, the electromagnetic inter-
ference through the screening/shielding of the bus
cable is conducted to earth on one side via the RC
network; on the other side, however, it is earthed via
the screening sleeve of a metal plug. Any equalizing
currents on the screening are therefore prevented by
the RC network.

1.3.2 Non-floating structure
Non-floating screening designs should be used prefer-
ably in the following cases:
– in small systems with low interference
– in bus environments with low-impedance,
star-shaped earthing
– with locally earthed slaves in conjunction with poten-
tial equalizing cables.
With non-floating structures, the electromagnetic inter-
ference through the screening/shielding of the bus
cable is earthed on both sides via the screening
sleeve of a metal plug.
A star-shaped low-impedance earthing or potential
equalizing cables are required for this purpose.
