2.1 About these instructions

This chapter contains general safety instructions which must be observed
when installing the function modules CMx in the control units CSM 7x0,
CFB 8x0 and CFB 9x.

Also closely observe further safety instructions in other chapters of these
installation instructions. Please read the safety instructions carefully before
starting the installation.

If safety instructions are ignored, severe or even fatal injuries may result,
as well as material losses and environmental damage.

2.2 Determined use

You can integrate the function modules CMx into the control units
CSM 7x0, CFB 8x0 and CFB 9x0.

2.3 Standards and directives

Safety | 5

The design and operation of this product conforms to the
European Directives and the supplementary national
requirements. Its conformity is confirmed by the CE
designation.

You may request the declaration of conformity for the
product. See rear page for contact details of your local
branch or from the relevant Bosch Thermotechnology
branch.

6 | Safety

2.4 Explanation of the symbols used

Two levels of danger are identified and signalled by the following terms:

RISK OF FATAL INJURY

Identifies possible risks associated with a product that might lead to
serious injury or even death if appropriate care is not taken.

WARNING!

RISK OF INJURY / SYSTEM DAMAGE

Identifies potentially dangerous situations, which might lead to
medium or slight injuries or to material damage

CAUTION!

USER INFORMATION

User tips for the optimum utilisation and adjustment of the appliance
plus other useful information.

2.5 Observe this information

The function modules CMx were designed and built according to the state
of the art and the recognised safety-related standards.

However, material losses resulting from incorrect installation cannot be
completely excluded.

Before installing the CM function modules, read these mounting
instructions carefully.

RISK TO LIFE

from electricity.

z The installation, electrical wiring, commissioning, electrical

WARNING!

connection, as well as maintenance and repairs must only be
carried out by a competent contractor who adheres to all current
technical regulations and requirements.

z Regional regulations should be observed in this regard!

6 720 803 029 (2011/08) Modules for control units CSM 7x0, CFB 8x0 and CFB 9x0

Observe the following safety instructions during the installation of the
function modules.

RISK TO LIFE

from electricity.

z Ensure that all electrical work is only carried out by an authorised

WARNING!

electrician.

z Before opening the control unit: Isolate all poles of the power

supply and secure against unintentional reconnection.

RISK TO LIFE

from electricity.

WARNING!

The risk of voltage flashes through unintentional loosening of the cores
at the terminals between the 230 V and the LV

1)

must be prevented.

z Therefore fix the wires from each cable away from each other

(e.g. with cable ties) or only strip the wire for a very short section.

1)

LV-terminal - extra low voltage connection for sensors, volt free connections and BUS.

DAMAGE TO THE APPLIANCE

through electrostatic discharge (ESD).

CAUTION!

z Before unpacking the modules touch a radiator or a earthed metal

water pipe to discharge any electrostatic charge in your body.

Safety | 7

2.6 Disposal

USER INFORMATION

Ensure that a regulation isolator is available to disconnect all poles
from the mains power supply. Install an isolator if none is available.

USER INFORMATION

Only use original replacement parts from Bosch Thermotechnology.
Bosch Thermotechnology cannot take responsibility for losses caused
by the use of parts not supplied by Bosch Thermotechniology.

z Electronic components must not be disposed of with general domestic

waste.
Dispose of old modules correctly through an authorised disposal site.

FM457/CMC 920

Control units which contain the function module FM457/CMC 920 should
be set as master. (Set as 0 if only one CSM 7x0 used, set as 1 if more than
1 CSM 7x0 used). Make this setting at the CM431 controller module.
