1 Safety instructions
Appropriate use
The device is to be used exclusively for measurement
tasks and directly related control tasks within the applica
tion limits detailed in the specifications. Use for any pur
pose other than the above is deemed to be non‐desig
nated use.
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.
The device is not intended for use as a safety compo
nent. Please also refer to the “Additional safety precau
tions" section. Proper and safe operation requires proper
transportation, correct storage, siting and mounting, and
careful operation.
Operating conditions
SProtect the device from direct contact with water.
SProtect the device from moisture and weather such as
rain or snow. To comply with the degree of protection
under the DIN EN60529 standard, all the cables must
be connected and any connectors not in use must be
fitted with protective caps
SDo not expose the device to direct sunlight

Safety instructions
6A2781-3.1 HBM: public CMD
SAs specified in EN 61326-1, Section 3.6, the connect
ing cables of the device must be no longer than 30 m
(when laid within a building) and must not leave the
building.
SThe CMD housing must be grounded to achieve EMC.
SComply with the maximum permissible ambient tem
peratures and the data on maximum humidity as
stated in the specifications.
SThe device must not be modified from the design or
safety engineering point of view except with our
express agreement. In particular, any repair or solder
ing work on motherboards (exchanging components)
is prohibited. When exchanging complete modules,
use only original parts from HBM.
SThe device is delivered from the factory with a fixed
hardware and software configuration. Changes can
only be made within the possibilities documented in
the manuals.
SThe device is maintenance free.
SPlease note the following points when cleaning the
housing (also see Chapter 13, page 61):
SDisconnect the device from all current and voltage
supplies before cleaning it.
SClean the housing with a soft, slightly damp (not wet!)
cloth. Never use solvent as this could damage the
labeling or the housing.
SWhen 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

Safety instructions
CMD A2781-3.1 HBM: public 7
be disposed of separately and not with normal house
hold garbage, see Chapter 15, page 80.
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
injury.
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
account all the safety aspects of measurement and auto
mation technology so that residual dangers are mini
mized. This particularly concerns personal and machine
protection. In the event of a fault, the relevant precau
tions must establish safe operating conditions.
General dangers of failing to follow the safety
instructions
The device is state of the art and reliable. The device
may give rise to residual dangers if it is inappropriately
installed or operated.
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.

Danger categories under ANSI
Symbol Significance
WARNING This marking warns of a potentially dangerous
situation in which failure to comply with safety
requirements can result in death or serious physical
injury.
CAUTION This marking warns of a potentially dangerous
situation in which failure to comply with safety
requirements can result in slight or moderate physical
injury.
Notice This marking draws your attention to a situation in
which failure to comply with safety requirements can
lead to damage to property.
Working safely
SThe device must not be directly connected to the
power supply system. The supply voltage must be
between 10 and 30 VDC.
SError messages should only be acknowledged once
the cause of the error is removed and no further dan
ger exists.
SMaintenance and repair work on an open device with
the power on may only be carried out by trained per
sonnel who are aware of the dangers involved.
SAutomation equipment and devices must be designed
in such a way that adequate protection or locking
against unintentional actuation is provided (e.g.
access 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.

Conditions on site
CMD A2781-3.1 HBM: public 15
5 Conditions on site
Important
Insulation resistance is crucial for piezoelectric transduc
ers; it should be greater than 1013 ohms.
To obtain this value, all the plug connections have to be
kept spotlessly clean. Positive or negative output voltage
signal drift indicates insufficient insulation resistance.
Clean the plug connector contacts with a clean, lint‐free
cloth (e.g. cleaning pad, HBM ordering number
1-8402.0026) and isopropanol, such as IPA200 from RS
Components. Cleaning agents used to clean SG measur
ing points are not suitable!
Also see Chapter 14 “Tips for piezoelectric measure
ment technology".
Notice
The degree of protection per DIN EN60529 is comply,
when all cables are connected and any unused connec
tions are fitted with protective caps.
Without protective caps, the device can also be damaged
before the boundary conditions of the particular protec
tion class are reached.
Important
As specified in EN 61326-1, Section 3.6, the connecting
cables of the charge amplifier must be no longer than 30
m (when laid within a building) and must not leave the
building.

Conditions on site
16 A2781-3.1 HBM: public CMD
5.1 Ambient temperature
The temperature has little effect on the output signal.
Temperature‐related measurement errors can be caused
by cooling or heating on one side (e.g. by radiant heat).
5.2 Moisture and humidity
Avoid moisture or a tropical climate. When the cable is
properly connected to the transducer and charge ampli
fier, the degree of protection of the charge amplifier is
comply, as per DIN EN 60529.

Mounting
CMD A2781-3.1 HBM: public 17
6 Mounting
The charge amplifier must be firmly attached to a level
support surface by two M4 bolts. This can be in any posi
tion. All CMD types have the same dimensions.
The signal inputs and outputs are electrically isolated
from the CMD housing. So no isolating elements are
necessary.
Important
If the device is used in highly electromagnetic environ
ments, we recommend grounding the housing. An M4
serrated washer can be inserted between the head of the
fastening bolt and the CMD housing to connect it to a
grounded base.
The fastening bolt is tightened with a tightening torque of
2 Nm, to ensure a metallic connection.
M4 toothed lock washer Mounting plate
M4 fastening screw (2 Nm min.
tightening torque)

Mounting
18 A2781-3.1 HBM: public CMD
Notice
Only connect the sensors to the CMD once they have
been mounted on the machine.
Sensors can deliver high charges during mounting, which
could damage the amplifier. Seal unused connections
with the supplied protective caps.
