Safety instructions

1 Safety instructions
Notice
The safety instructions described here also apply to the
power pack NTX001 and the active backplane BPX001
and BPX002.
Appropriate use
A module integrated into the CANbus by the relevant
connector is to be used exclusively for measurement and
test tasks. Use for any purpose other than the above is
deemed to be non-designated use.
To ensure safe operation, the module must only be ope
rated as described in the general operating manual and in
accordance with the information detailed in this document.
It is also essential to comply with the legal and safety re
quirements for the application concerned during use. The
same applies to the use of accessories.
Each time you start up the module, you must first run a
project planning and risk analysis that takes into account
all the safety aspects of automation technology. This par
ticularly concerns personal and machine protection.
Additional safety precautions must be taken in plants
where malfunctions could cause major damage, loss of
data or even personal injury. In the event of a fault, these
precautions establish safe operating conditions.
This can be done, forexample, by mechanical
interlocking, error signaling, etc.

Safety instructions
6A4461-2.0 HBM: public CANBus
Notice
The module must not be connected directly to a power
supply system. The supply voltage must be 10 V … 30 V
(DC).
General dangers of failing to follow the safety
instructions
Every module is a state of the art device and as such is
failsafe. The module may give rise to residual dangers if
it is inappropriately installed and operated by untrained
personnel. Any person instructed to carry out installation,
commissioning, maintenance or repair of the modules
must have read and understood the Operating Manuals
and in particular the technical safety instructions.
The scope of supply and performance of the modules
only covers a small area of measurement technology. In
addition, equipment planners, installers and operators
should plan, implement and respond to the safety
engineering considerations of measurement technology
in such a way as to minimize residual dangers. On-site
regulations must be complied with at all times. There
must be reference to the residual dangers connected
with measurement technology. After making settings and
carrying out activities that are password-protected, you
must make sure that any controls that may be connected
remain in safe condition until the switching performance
of the module has been tested.

Safety instructions
CANBus A4461-2.0 HBM: public 7
Maintenance and cleaning
The modules are maintenance-free.
SBefore cleaning, disconnect all connections.
SClean the housing with a soft, slightly damp (not wet!)
cloth. Never use solvent, as this could damage the
label or the housing.
SWhen cleaning, ensure that no liquid gets into the
module or connections.
Bus connecting and Outputs
Particular attention must be paid to safety when
connecting to the CANbus and when sending CANbus
messages. Ensure that integration alone, status or
control signals cannot initiate any actions that may pose
a danger to persons or the environment.
Product liability
In the following cases, the protection provided for the
device may be adversely affected. Liability for device
functionality then passes to the operator:
SThe device is not used in accordance with the operat
ing manual.
SThe device is used outside the field of application de
scribed in this section.
SThe operator makes unauthorized changes to the
device.
Warning signs and danger symbols
Important instructions for your safety are specifically
identified. It is essential to follow these instructions in
order to prevent accidents and damage to property.

Safety instructions
8A4461-2.0 HBM: public CANBus
Safety instructions are structured as follows:
WARNING
Type of danger
Consequences of non-compliance
Averting the danger
SWarning sign: draws attention to the danger
SSignal word: indicates the severity of the danger
(see table below)
SType of danger: identifies the type or source of the
danger
SConsequences:describes the consequences of non-
compliance
SDefense: indicates how the danger can be avoided/
bypassed.
Danger classes as per ANSI
Warning sign, signal word Meaning
WARNING This marking warns of a potentially dangerous situ
ation in which failure to comply with safety require
ments may result in death or serious physical injury.
CAUTION This marking warns of a potentially dangerous situ
ation in which failure to comply with safety require
ments may result in slight or moderate physical injury.
Note This marking draws your attention to a situation in
which failure to comply with safety requirements may
lead to damage to property.
