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.
