During the use of the system, it might be possible to access another parts of a more comprehensive
system. Please read and follow the safety instructions provided in the manuals of all other components
regarding warning and security advices for using the system.
With this product, only use the power cable delivered or dened for the host country.
DO NOT connect or disconnect sensors, probes or test leads, as these parts are connected to a voltage
supply unit.
The system is grounded via a protective conductor in the power supply cord. To avoid electric shocks,
the protective conductor has to be connected with the ground of the power network. Before connecting
the input or output connectors of the system, make sure that there is a proper grounding to guarantee
potential free usage. For countries, in which there is no proper grounding, please refere to your local
legally safety regulations for safety use.
DC systems: Every DC system has a grounding connected to the chassis (yellow/green safety banana
plug).
Please note the characteristics and indicators on the system to avoid re or electric shocks. Before
connecting the system, please carefully read the corresponding specications in the product manual.
The inputs are not, unless otherwise noted (CATx identication), for connecting to the main circuit of
category II, III and IV.
The power cord separates the system from the power supply. Do not block the power cord, since it has to
be accessible for the users.
DO NOT use the system if equipment covers or shields are removed.
If you assume the system is damaged, get it examined by authorised personnel only.
Any use in wet rooms, outdoors or in adverse environmental condition is not allowed!
Adverse environmental conditions are:
Moisture or high humidity
Dust, ammable gases, fumes or dissolver
Thunderstorm or thunderstorm conditions (except assembly PNA)
Electrostatic elds, et cetera.
The measurement category can be adjusted depending on module conguration.
Any direct voltage output is protected with a fuse against short cut and reverse-polarity, but is NOT
galvanically isolated (except it is explicit marked on the system).

General description
Having wide distance between the DEWE-30-xx and the data acquisition unit (DEWE-5000, DEWE-4010,
DEWE-3020, DEWE-2010 …) causes some problems if high bandwidth and low distortion and noise is re-causes some problems if high bandwidth and low distortion and noise is re-
quired. Similar to all high speed digital signal layer protocols (LAN, IEEE1394, USB, PCI-Express) symmetric
signal transfer using twisted pair cables have to be used to achieve this. The 30-16-DIFF-OUT converts the
standard single ended DEWE-30 output to a balanced differential output with high output current, needed to
drive cables up to 500 m without loosing the high accuracy of the signal amplier.
Cable conguration
The usage of shielded twisted pair cables is recommended for the connection between DEWE-30-xx and the
data acquisition unit.
Please note that at the data acquisition unit differential input ampliers are needed.
The shield of the cable have to be connected to the GND pin of the 37-pin female SUB-D connector of
the DEWE-30-xx. In usual system conguration the GND of the DEWE-30-xx and the GND of the data
acquisition unit are tied together via the personal earth of the AC power supply. Therefore the cable shield
should not be connected to the GND of the data acquisition system to avoid GND loops. But if the GND of
both devices are nowhere tied together (at power supply without protected earth) it is also recommended to
connected the shield to the GND of the data acquisition device.
