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

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:

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.

WARNING!

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.

CAUTION!

RISK OF INJURY / SYSTEM DAMAGE

Identifies potentially dangerous situations, which might lead to

medium or slight injuries or to material damage

USER INFORMATION

User tips for the optimum utilisation and adjustment of the appliance

plus other useful information.

WARNING!

RISK TO LIFE

from electricity.

zThe installation, electrical wiring, commissioning, electrical

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.

zRegional regulations should be observed in this regard!

Safety | 7

Observe the following safety instructions during the installation of the

function modules.

2.6 Disposal

zElectronic components must not be disposed of with general domestic

waste.

Dispose of old modules correctly through an authorised disposal site.

WARNING!

RISK TO LIFE

from electricity.

zEnsure that all electrical work is only carried out by an authorised

electrician.

zBefore opening the control unit: Isolate all poles of the power

supply and secure against unintentional reconnection.

WARNING!

RISK TO LIFE

from electricity.

The risk of voltage flashes through unintentional loosening of the cores

at the terminals between the 230 V and the LV1)

must be prevented.

zTherefore 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.

CAUTION!

DAMAGE TO THE APPLIANCE

through electrostatic discharge (ESD).

zBefore unpacking the modules touch a radiator or a earthed metal

water pipe to discharge any electrostatic charge in your body.

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.

3.2 Arrangement of the modules in the control unit (CSM 7x0)

ZM424 and FM455/CMC 900 (only for CSM 750)

The module FM455/CMC 900 always occupies slot A (ÆFig. 1, [4]) and the

module ZM424 slot 1 (ÆFig. 1, [1]).

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.
