pressed. This means that the keyboard can also be used in snow and ice.
3. General description
Series 09 Rugged Keypads offer high reliability: The robust, modular design with protection
degrees of up to IP6K7 and the possibility of customer specific adaptations and the
arrangement of symbol inserts predestine the devices for use in heavy-duty and special
vehicles. The modules are as well designed for ECE certification.
Harsh environmental conditions and low back panel depth require a robust and compact
product design. In addition, the control and signalling devices must be precisely configurable
both mechanically and electronically for the respective application. The high-quality Rugged
Keypad meets these requirements with a cutting-edge system integration.

7. Mechanical installation/mounting
2 mounting versions are available: Installation in a panel by means of retaining clamps
(retaining clamp version) or screws (screw-in version).
Installation in a panel by means of retaining clamps
(retaining clamp version)
See drawing “1707 product information (drawing no. 1707940001)”.
If the keypad is mounted or dismounted several times, new retaining clamps must be used
each time to prevent settling effects. To change the retaining clamps, press the clamp flat on
the underside, then you can push out and dismount the retaining clamp.
The marking of the retaining clamp for the respective front panel thickness is imprinted as
number 1 to 4 on the clamp, which is also visible when mounted. The number 1 on the retaining
clamp means that it is suitable for a front panel thickness of 1mm. A mixed use of different
types of retaining clamps in a keypad is not permitted.
The keypad shall be pressed evenly into the panel of the customers application, with the
mounted retaining clamps, while tilting should be avoided. Press evenly on the housing and
not on the buttons.
Note
Damage to the buttons
The plug-in connection must be established with a suitable connector. The plug-in connection
can alternatively be established before or after mounting the keypad into the panel.
The keypad is automatically centred to the panel by the 6 retaining clamps, i.e. the exact
positioning of the keypad depends on the accuracy and size of the installation opening.

www.eao.com 13
Installation in a panel with self-locking nuts (screw-in
version)
See drawing “1707 product information”.
If the keypad is mounted or dismounted several times, new self-locking nuts must be used
each time.
Caution!
Exceeding the maximum permissible torque inevitably leads to the
destruction of the keypad. The keypad might be no longer
tight nor leak
proof in this case.
Incorrect mounting of the keypad, e.g. incorrect number of rubber washers
or without washers (see 7.2.1 Mounting sequence), may result in damages
to the keypad.
Risk of injury
Damage to the keypad
Electric shock
7.2.1 Mounting sequence
First, the accurate number of rubber washers need to be mounted according to the front panel
thickness. No rubber washers are necessary for a front panel thickness of 1 mm. Use 1 rubber
washer per screw bolt for a front panel thickness of 2 mm, use 2 rubber washers per screw
bolt for a front panel thickness of 3 mm and use 3 rubber washers per screw bolt for a front
panel thickness of 4 mm. Since these have a slightly smaller inner diameter, they clamp lightly
on the thread of the bolt to make it more difficult for the washers to fall off. Afterwards, the
keypad must be installed in the front panel, of the customer application. The sleeve can be
installed rotated by 180° in each case. Afterwards, the 4 washers have to be installed over the
screw bolts and fixed with the nuts. The correct tightening torque is defined in the 1707 product
information and must be observed! The last assembly step is to connect the plug connector.
The keypad of the screw-in version must be aligned manually to the panel. The Keypad will
not be automatic centered. In the next assembly step the keypad can be slightly pushed into
the mounting panel (depending on the opening size of the panel).

www.eao.com 14
Caution!
For both versions, make sure that the opening for pressure and humidity
compensation on the underside of the keypad is not blocked, damaged or
covered during installation and afterwards.
Damage to the keypad
Installation of the symbol inserts
The symbol inserts can be changed in a panel both in the installed and in the non-installed
state of the keypad.
Each symbol insert can be installed rotated in a 90° grid. When mounting the symbol inserts,
make sure that the position of the symbols has the desired orientation towards the keypad.
The symbol inserts have a mechanical coding to the housing of the keypad. A slight twisting
of the symbol inserts to the keypad is technically possible and does not constitute a defect.
The symbol inserts must be mounted / dismounted under the edge of the housing around the
insert using a tool without sharp edges (similar to mounting a vehicle tyre on a rim). The insert
tool (article number: 09-0A00.0001), which is available as an accessory, is best suited for this.
There should be no visible gap between the housing of the keypad and the symbol insert after
installation, because dirt may penetrate here during operation and may negatively influence
the lighting function of the keypad.

www.eao.com 15
Caution!
When mounting and dismounting the symbol inserts, make sure that the
housing is not damaged. The silicone of the housing must not be pierced,
otherwise the protection degree of the keypad is not fulfilled. Similarly, the
coating of the housing must not be damaged, otherwise the chemical
resistance of the keypad is no longer guaranteed.
Damage to the keypad like cracks to the soft part of the keypad
Loss of tightness of the keypad
It must be always ensured that the symbol inserts are mounted in the correct
position.
Risk of injury
Note
When changing the symbol inserts, make sure that there are no liquids or
impurities
between the housing and the symbol insert. These would
negatively affect the illumination of the symbols.
When using the version for snap-in mounting in a mounting panel, you need
retaining clamps.
When using the version for screw-in mounting in a mounting panel, you
need the sleeve, nuts, washers and spacers to bridge the distance between
keypad and sleeve in the thickness of the mounting panel.
Do not forget the spacers during mounting. Only hand-tighten the self-
locking nuts (see also 1707 product information).
Damage to the keypad and/ or sleeve
Note
Only use original mounting material and optional accessories.
Damage to the keypad
Use inside closed vehicles
Due to the product is designed for outdoor applications and not for use in closed vehicle
interior, odor testing according to odor testing specifications like VDA270 is in customer’s
responsibility. The test should be performed to customer application needs.

www.eao.com 16
8. Electrical installation and pinning
Electrical installation shall only be done when the system is under no power.
Connection of the keypad module is realized with the Wuerth WR-MPC3 16 pin female
connector DT04-6P which is mounted on the PCB.
Caution!
The customer
application electrical system must be equipped with an
overvoltage protection like a sufficiently selected suppressor diode to clip
possible incoming overvoltage peaks before they arrive at the keypad
according to DIN EN 16750-2 (Load Dump Test B).
Damage to the keypad
Please refer to „1707 product information”.
Picture 1 shows the internal electrical circuit of the keypad. To reduce power dissipation and
to prevent overheating of the keypad, a variant for 12 V (supply voltage range: 18 V – 32 V)
are available. The pinning of the connector of these two variants are identically.
Picture 1: Internal electrical circuit of the keypad
The symbol and halo illumination of a button uses the same ground on pin 8 and 9 of WR-
MPC3. Each halo ring can be switched on by connecting pin 1-6 of connector with positive
power supply. The symbol illumination can only be switched on for all buttons at once by
connecting pin 7 of the connector to positive power supply.

www.eao.com 17
The switching system is separated from the symbol and halo ring illumination and use a
common line on pin 10. Each button has a Namur-circuit (only available in option Namur circuit)
consisting of a series and a parallel resistor. The keypad can be ordered with or without Namur
functionality. With Namur functionality the series and parallel resistor have the following values:
Rp = 1 kΩ
Rs = 120 Ω
Without Namur-functionality the values of the resistors are:
Rp = not placed
Rs = 0 Ω
Furthermore, it is necessary to debounce the switches. This can be done via software or
hardware in the control unit connected to the keypad. The debounce time should be greater
than 10ms.

www.eao.com 18
9. Cleaning
Cleaning with water and commercially available soft cloths is possible. Do not use aggressive
solvents. Please ensure that the distance between the nozzle and the product is not less than
0.5 m when using a high-pressure water jet.
Caution!
Cleaning with a high-
pressure water jet is not permitted with a distance
nozzle to product less than 0.5 m.
Damage to the keypad
Electrical shock due to leakage of the keypad
10. Optional accessories
Symbol inserts with customer specific symbols or alternatively according to ISO 7000 can be
procured. Symbol inserts without symbols (blanks, colored) can also be procured.
11. Liability for quality defects
The general function of the keypad has been tested at the factory before delivery. However, if
errors occur despite the careful quality control, they must be reported immediately to EAO or
the dealer.
The liability for quality defects is 12 months for the delivered products. Within this period, faulty
parts, except wear parts, will be repaired or replaced free of charge if the keypad is returned
to EAO, free of charge in the event EAO is responsible for the defect.
Damages caused by improper use, or the use of force are excluded from the liability for quality
defects. Damages caused by repairs or modifications to the keypad are also excluded. EAO is
exclusively responsible for repairs to the keypad.
Further claims cannot be asserted. Claims arising from the purchase contract remain
unaffected.
EAO is not liable for consequential damages. The right to design changes, in the sense of
product improvement, is reserved by EAO.
