1 About these operating instructions

This document presents the CISS operating instructions, as well as detailed CISS sensor characteristics, communication

and management features through Bluetooth and USB communication.

This document refers to the CISS firmware version V02.03.00.

The latest firmware version and detailed instructions how to proceed are available at:

https://www.bosch-connectivity.com/media-and-downloads/

(CISS Firmware Update V.nn.nn.nn / CISS Firmware Update Operating Instructions).

Ensure that the CISS is working correctly by reading these instructions carefully before using the CISS in your planned
use case.

1.1 Definition of special notices

Warning: Indicates a hazard that could lead to minor or moderate injuries.

Always follow these instructions

Note: Points of emphasis and reminders of operational peculiarities for the device that could affect performance.

Always follow these instructions.

1.2 Definition of general notices

2 Safety and environment

Warning: Do not open the housing without authorization!

Opening the housing without authorization will void any warranty and includes risks of injury to the user.
Using the CISS according to its intended use and functionalities does not require the opening of the housing.

Do not open the housing.

2.1 Radio frequency radiation exposure and further information

The radiated output power of the device is far below the FCC radio frequency exposure limits. Nevertheless, the device

shall be used in such a manner that the potential for human contact during normal operation is minimized (see device
specification, chapter 4.3).

2.2 Disposal

Disposing of this product correctly will help save valuable resources and prevent any potential negative effects on human
health and the environment, which could otherwise arise from inappropriate waste handling. Please contact your local
authority for further details of your nearest designated collection point. Penalties may be applicable for incorrect disposal
of this waste, in accordance with your national legislation. For further information, please refer to chapter 9.5.

INFO: General information and instructions that must be followed

TIP: Practical advice

3 Introduction and intended use

The CISS is a multi-sensor device detecting acceleration, angular velocity and magnetic fields, as well as environmental

conditions (temperature, humidity, light, air pressure, and noise). The robust housing and the small outline makes it
perfectly suitable for industrial retrofit applications, such as condition monitoring and predictive maintenance.

Configuring the device enables the user to address a broad variety of use cases, including interpreting the sensor data
by smart algorithms.

3.1 Intended use

The CISS operates according to the information provided in the operating instructions and the data sheet.

Validation and testing of any use or operation, which requires specific requirements and standards, which are not explicitly
mentioned in these documents, is the customer’s responsibility.

Please also see chapter 9.6 Restrictions of use.

Using the CISS with non-real-time operating systems (eg. Windows or Linux) might cause problems during the data
transmission. Increased utilisation of the target system might cause data loss or – in extreme cases - an interruption of
the data transfer.

4 Technical specification

4.1 Housing

The CISS is built from a robust, industrially-suited housing with a suitable connector, that can be fixed at the housing via

a fixing bracket.

The compact design of the CISS fits perfectly in different industrial applications and also allows an easy and user-friendly

mounting in difficult to access environments.

For mounting instructions, please refer to chapter 5.1. Mounting the CISS.
