1 Safety instructions
Intended use
The DMP41 precision measuring instrument (referred to as the DMP41 in
the following document) is to be used exclusively for measurement tasks
and directly related control tasks. Use for any purpose other than the above
is deemed to be non-designated use.
In the interests of safety, the DMP41 should only be operated as described
in the operating manual. It is also essential to comply with the legal and
safety requirements for the relevant application during use. The same
applies to the use of accessories.
General dangers of failing to follow the safety instructions
The DMP41 is state of the art and failsafe. The DMP41 may give rise to
residual dangers if it is inappropriately installed and operated by untrained
personnel.
Any person instructed to carry out installation, startup, maintenance or re
pair of the DMP41 must have read and understood the operating manual
and in particular the technical safety instructions.
Conditions at the place of installation
SProtect the DMP41 from direct contact with water.
SProtect the DMP41 from moisture or weather conditions such as rain,
snow, etc. The protection class under the IP standard DIN EN 60 529, is
IP20.
SDo not expose the DMP41 to direct sunlight.
SKeep all ventilation slots open to ensure unhindered air flow.
SFor installation in 19" electrical enclosures, due to poorer heat
dissipation, measures must be taken to ensure that the maximum
permitted ambient temperature (+50°C) is not exceeded. We recommend
forced venting in any case and in especially critical cases, intermediate
spaces between the upper and lower rack frames.
SPlease comply with the maximum permitted ambient temperatures
(èsee Technical Data sheet). Do not operate the DMP41 when the
ambient temperature is below +5°C or over +50°C.

Safety instructions
8A03470_07_E00_00 HBM: public DMP41
SThe permissible relative humidity at 31°C is 80% (non condensing);
linear reduction up to 50% at 40°C.
SThe DMP41 is classified in overvoltage category II, degree of pollution 2.
SInstall the DMP41 so that it can be disconnected from the mains at any
time without difficulty.
SIt is safe to operate the DMP41 up to a height of 2000 m.
Residual dangers
The scope of supply and performance of the DMP41 covers only a small
area of measurement technology. In addition, equipment planners, installers
and operators should plan, implement and respond to the safety en
gineering considerations of measurement technology in such a way as to
minimize residual dangers. On-site regulations must be complied with at all
times.
After making settings and carrying out activities that are password-
protected, you must make sure that any controls that may be connected
remain in a safe condition until the switching performance of the DMP41 has
been tested.
Maintenance and cleaning
The DMP41 is maintenance free.
SBefore cleaning, disconnect the module from all connections.
SClean the housing with a soft, slightly damp (not wet!) cloth. You should
never use solvent, since this could damage the labeling on the front
panel and destroy the display.
SWhen cleaning, ensure that no liquid gets into the DMP41 or on the
connections.

Product liability
In the following cases, the protection provided for the DMP41 may be
adversely affected. Liability for equipment functionality then passes to the
operator:
SThe DMP41 is not used in accordance with the operating manual.
SThe DMP41 is used outside the field of application described in this
chapter.
SThe operator makes unauthorized changes to the DMP41.
Working safely
Before starting up, ensure that the circuit used is sufficiently protected.
The mains plug must only be inserted into a socket with a protection switch
(protection class I).
The DMP41 must be switched off and the mains plug disconnected from the
socket before opening the DMP41.
Never pull the mains plug out of its socket by the supply lead.
Do not operate the DMP41 if the mains lead is damaged. If you need to re
place the mains cable, order a new one with ordering number 1-KAB274-…
(èalso see Chapter 3.3 “Scope of supply”, Page 18), or ensure that you
use an equivalent cable.
If the DMP41 is used as a built-in instrument, it must only be operated in the
enclosure provided.
The DMP41 meets the safety requirements of DIN EN 61010 Part 1
(VDE 0411 Part 1) (overvoltage category II) and DIN EN 61010-2-030.
To ensure adequate immunity from interference, use only the Greenline
shielding concept (see separate HBM publication: "Greenline shielding
design", downloadable from the Internet at http://www.hbm.com/Greenline).
Safety precautions must be taken both in terms of hardware and software,
so that a line break or other interruptions to signal transmission, such as via
the bus interfaces, do not cause undefined states or loss of data in the
automation device.
Error messages should only be acknowledged once the cause of the error is
removed and there is no further danger.
Only carry the DMP41 using the carrying handles.

Electromagnetic compatibility
The DMP41 has been tested based on EMC product standard EN
61326-1:2013. This standard includes definitions of limit values and test
levels for various electromagnetic environments.
Regarding emission (EME), requirements are included for class A (industrial
environments) and class B (residential, business and commercial
environments as well as small businesses). Laboratory applications also
usually require class B.
The product standard here references to EN 55011:2009+A1:2010.
Regarding immunity to interference, the product standard includes require
ments for controlled electromagnetic environments (lowest requirements),
general environments and industrial environments (highest requirement).
The DMP41 satisfies the following requirements:
SEmission (EME): Class B (see Note)
SImmunity to interference: Industrial environment
Note on emission (EME): The DMP41 is supplied ex works i.a. with a mains
cable and an adapter cable (USB to RS232). These cables are fitted with
ferrites to minimize emission (EME) and must not be removed. The require
ments of Class B are only satisfied when the ferrites are fitted.
Should the ferrites have been inadvertently removed, they must be attached
to the cables as close as possible to the DMP41.
