CP..EA 9611A III

Designated use
The CP modules described in this manual are desig-
nated exclusively for use in conjunction with the Festo
CP field bus node. The CP modules and CP cables
may only be used as follows:
- as intended for use
- in original condition
- without unauthorized modifications
- in faultless technical condition
If used in conjunction with commercially-available com-
ponents such as sensors and actuators, the specified
limit values for pressures, temperatures, electrical data,
torques etc. must be observed. Please comply also with
national and local safety laws and regulations.
All CP modules comply with protection class III.
WARNING
An isolating transformer as per EN 60742 (IEC 742,
DIN/VDE 0551) with at least 4 kV isolation resist-
ance is required for reliable electrical isolation of the
operating voltages.
IV CP..EA 9611A

Target group

Pictograms and symbols complement the danger warn-
ings and draw attention to the nature and conse-
quences of dangers.
Pictograms
The following pictograms are used:
Uncontrolled movements of loose tubing.
Unintentional movements of the connected actuators.
High voltages or undefined switching states of the elec-
tronic components which may influence connected cir-
cuits.
Electrostatically vulnerable components.
These will be damaged if you touch the contact sur-
faces.

1.2 Fitting
Input modules are intended for fitting onto walls or hat
rails. For fitting them onto walls you will require the fol-
lowing surface areas:
Type Surface area
CP-E16-M8 approx. 150 x 66 mm2
CP-E16-M12x2 approx. 141 x 78 mm2
The diagram below shows the dimensions of the four
threaded holes of screw size M4.

PLEASE NOTE
For fitting the modules onto a hat rail you will require
fastening kit CP-TS-HS35. This kit contains 2 fasten-
ings, 2 M4x12 screws and 2 washers.
In order to fit the modules onto a hat rail, proceed as
follows:
Fitting onto a
hat rail
1. Make sure that the fastening surface can support
the weight of the module.
2. Fit a hat rail (support rail EN 50022 - 35x15; width
35 mm, height 15 mm).
3. Fasten the hat rail at least every 100 mm to the sup-
port surface.
4. Let both fastenings on the hat rail snap into the
module (see Fig. 1/3).
5. Screw the housing on to the fastening with the
screws supplied as shown in the diagram below.
6. Tighten the screws. The fastening and the housing
will then be clamped tight on the hat rail.

1.3 Installation
WARNING
Before undertaking installation work, switch off
the following:
- the power supply to the CP field bus node
- the power supply to all the output modules.
You thereby avoid:
– unintentional movements of the connected
actuators.
– undefined switching states of the
electronic components.
WARNING
Connect a protective earth cable to the functional ear-
thing contact (see Fig. 1/1).
You thereby avoid:
– interference caused by electromagnetic sources.

1.3.1 Connecting sensors
Use the following cable and plugs for connecting the
sensors.
Type Plug Cable
CP-E16-M12x2 PG7 KM12-DUO-...
CP-E16-M8 Use the plug with
union nut with
thread M8x1.
KM8-M8-GSGD-...
Fasten the plugs with the aid of the union nuts in order
to avoid unintentional loosening e.g. due to vibration.
Seal the unused sensor connections with the protective
caps supplied. Only then is compliance with class of
protection IP65 ensured.
