1 Safety instructions
Appropriate use
PAD digital transducer electronics are to be used exclus
ively for measurement tasks and directly related control
tasks within the application limits detailed in the specifica
tions. Any other use is not appropriate.
Any person instructed to carry out installation, commis
sioning or operation of the device must have read and
understood the Operating Manual and in particular the
technical safety instructions.
In the interests of safety, the device should only be oper
ated by qualified personnel and as described in the Oper
ating Manual. It is also essential to comply with the legal
and safety requirements for the application concerned
during use. The same applies to the use of accessories.
PAD is not intended for use as a safety component.
Please also refer to the "Additional safety precautions"
section. Proper and safe operation requires proper trans
portation, correct storage, siting and mounting, and care
ful operation.
Operating conditions
SPlease observe the allowed maximum values stated
in the specifications for:
- Max. supply voltage
- Max. voltage for inputs and outputs
- Max current of outputs
- Temperature limits
SMake sure that the max. current for plugs and sockets
is adhered to in bus mode.

Safety instructions
PAD4002A A4243-1.0 HBM: public 5
SThe device must not be modified from the design or
safety engineering point of view except with our ex
press agreement. In particular, any repair or soldering
work on motherboards (exchanging components) is
prohibited.
SThe device is delivered from the factory with a fixed
hardware and software configuration. Changes can
only be made within the possibilities listed in the cor
responding documentation.
SThe device is maintenance free.
SPlease note the following points when cleaning the
housing:
- Disconnect the device from all current and voltage
supplies before cleaning it.
- Clean the housing with a soft, slightly damp cloth.
Never use solvent, as this could damage the label
or the housing.
- When cleaning, ensure that no liquid gets into the
device or connections.
SIn accordance with national and local environmental
protection and material recovery and recycling regula
tions, old equipment that can no longer be used must
be disposed of separately and not with normal house
hold garbage, see Chapter9 on page31.
Qualified personnel
Qualified persons means persons entrusted with the in
stallation, fitting, commissioning and operation of the
product who possess the appropriate qualifications for
their function.
This includes people who meet at least one of the three
following requirements:

Safety instructions
6A4243-1.0 HBM: public PAD4002A
SKnowledge of the safety concepts of measurement
and automation technology is a requirement and as
project personnel, they must be familiar with these
concepts.
SAs measurement or automation plant operating per
sonnel, they been instructed how to handle the ma
chinery. They are familiar with the operation of the
equipment and technologies described in this docu
mentation.
SAs commissioning engineers or service engineers,
they have successfully completed the training to qual
ify them to repair the automation systems. They are
also authorized to activate, ground and label circuits
and equipment in accordance with safety engineering
standards.
Working safely
SThe device must not be directly connected to the
power supply system. The supply voltage must be
between 12 and 30VDC.
SError messages should only be acknowledged once
the cause of the error is removed and no further
danger exists.
SAutomation equipment and devices must be designed
in such a way that adequate protection or locking
against unintentional actuation is provided (e.g. ac
cess checks, password protection, etc.).
SFor those devices operating in networks, safety pre
cautions must be taken both in terms of hardware and
software, so that a line break or other interruptions to
signal transmission do not cause undefined states or
loss of data in the automation device.

Safety instructions
PAD4002A A4243-1.0 HBM: public 7
SAfter making settings and carrying out activities that
are password-protected, ensure that any controls that
may be connected remain in a safe condition until the
switching performance of the device has been tested.
Additional safety precautions
Additional safety precautions to meet the requirements of
the relevant national and local accident prevention regu
lations must be taken in plants where malfunctions could
cause major damage, loss of data or even personal in
jury.
The scope of supply and performance of the device cov
ers only a small area of measurement technology. Before
starting up the device in a system, a project planning and
risk analysis must first be implemented, taking into ac
count all the safety aspects of measurement and auto
mation technology so that residual risks are minimized.
This particularly concerns personal and machine protec
tion. In the event of a fault, the relevant precautions must
establish safe operating conditions.
General dangers of failing to follow the safety
instructions
The device is state of the art and failsafe. The device
may give rise to residual dangers if it is inappropriately
installed or operated.
