Das Equipment Management - Plug-in Connect Module... is used to transmit important status and usage data from a device. These installation instructions describe the installation and commissioning.

These installation instructions apply to the following implement interfaces:

• 2.644-391.0

• 2.600-011.0

• Place the device on a level surface.

• Switch off the device.

• Turn the program selection switch to position "0".

• If present: Pull out the KÄRCHER Intelligent Key (KIK) on the control panel.

• Disconnect the battery.

• Determine a suitable position for the Plug-In Connect Module and the antenna in the device (see Determine the position for the Plug-in Connect Module and the antenna).

The following requirement should be met by the position for attachment:

• The Plug-in Connect Module must be fitted in such a way as to ensure the best possible transmission of the device's vibrations.

  Note

  Move the Plug-in Connect Module near the main unit (e.g. turbine, motors) of the device (for an example of the attachment, see Machine Integration and Installation Spaces).

• The antenna must be glued to the outer wall inside the device.

• The shielding by components such as metal and electronic components as well as e.g. the fresh water tank should be as low as possible.

• The adhesive surface should be as flat as possible.

• The Plug-in Connect Module should only be in contact with the machine at the adhesive surface when the device is ready for operation. The remaining outer surfaces of the module should be exposed.
