Calibration
Every instrument needs to be calibrated at regular intervals. The standard norm across nearly every industry is
annual calibration. Before your DEWETRON data acquisition system is delivered, it is calibrated at our DEWETRON
headquater. Each of this system is delivered with a certificate of compliance with our published specifications.
Detailed calibration reports from our calibration system are available for purchase with each order. We retain them
for at least one year, so calibration reports can be purchased for up to one year after your system was delivered.
Support
DEWETRON has a team of people ready to assist you if you have any questions or any technical difficulties regarding
the system. For any support please contact your local distributor first or DEWETRON directly.

SAFETY INSTRUCTIONS
Your safety is our primary concern! Please be safe!
> Use this system under the terms of the specifications only to avoid any possible danger. If the unit is used
in a manner not specified by the manufacturer the protection can be impaired!
> Ths product is intended for use in industrial locations. As a result, this product may cause interference
if used in residential areas. Such use must be avoided unless the user takes special measures to reduce
electromagnetic emissions to prevent interferences to the reception of radio and television broadcasts.
> Maintenance will be executed by qualified staff only.
> 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 defined 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 fire or electric shocks. Before
connecting the system, please carefully read the corresponding specifications in the product manual.
> The inputs are not, unless otherwise noted (CATx identification), for connecting to the main circuits of
category II, III and IV. The measurement category can be adjusted depending on module configuration.
> 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.
> Supply overvoltage category is II.
> 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, flammable gases, fumes or dissolver
> Thunderstorm or thunderstorm conditions (except assembly PNA)
> Electrostatic fields, et cetera.
> 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).
> The system must be connected and operated to an earthed wall socket at the AC mains power supply
only (except for DC systems).
> Any other use than described above may damage your system and is attended with dangers like shortcut,
fire or electric shocks.

General safety and hazard warnings for all DEWETRON systems

11
450135 • EPAD2/CPAD2/CPAD3 Modules • Technical Reference Manual • Prinng version 1.0.6 • December 1st, 2020
> The whole system must not be changed, rebuilt or opened (except for changing TRION™ modules).
> If you assume a more riskless use is not provided anymore, the system has to be rendered inoperative
and should be protected against inadvertent operation. It is assumed that a more riskless operation is not
possible anymore, if
> the system is damaged obviously or causes strange noises.
> the system does not work anymore.
> the system has been exposed to long storage in adverse environmental.
> the system has been exposed to heavy shipment strain.
> DO NOT touch any exposed connectors or components if they are live wired. The use of metal bare wires
is not allowed. There is a risk of short cut and fire hazard!
> Warranty void if damages caused by disregarding this manual. For consequential damages NO liability
will be assumed!
> Warranty void if damages to property or persons caused by improper use or disregarding the safety
instructions.
> Unauthorized changing or rebuilding the system is prohibited due to safety and permission reasons (CE).
Exception: changing DAQP/PAD/HSI/TRION™/TRION3™ modules.
> The assembly of the system is equivalent to protection class I. For power supply, only the correct power
socket of the public power supply must be used, except the system is DC powered.
> Be careful with voltages >25 VAC or >35 VDC! These voltages are already high enough in order to get a
perilous electric shock by touching the wiring.
> Unless otherwise stated, maximum input voltage for measuring cards are 70 VDC and 46.7 VPEAK.
> The product heats during operation. Make sure there is adequate ventilation. Ventilation slots must not
covered!
> Only fuses of the specified type and nominal current may be used. The use of patched fuses is
prohibited.
> Prevent using metal bare wires! Risk of short cut and fire hazard!
> DO NOT use the system before, during or shortly after a thunderstorm (risk of lightning and high energy
overvoltage). An advanced range of application under certain conditions is allowed with therefore
designed products only. For details please refer to the specifications.
> Make sure that your hands, shoes, clothes, the floor, the system or measuring leads, integrated curcuits
and so on, are dry.
> DO NOT use the system in rooms with flammable gases, fumes or dust or in adverse environmental
conditions.
> Avoid operation in the immediate vicinity of:
> high magnetic or electromagnetic fields
> transmitting antennas or high-frequency generators
For exact values please refere to enclosed specifications.
> Use measurement leads or measurement accessories aligned to the specification of the system only. Fire
hazard in case of overload!
> Do not switch on the system after transporting it from a cold into a warm room and vice versa. The
thereby created condensation may damage your system. Acclimatise the system unpowered to room
temperature.
> Do not disassemble the system! There is a high risk of getting a perilous electric shock. Capacitors still
might charged, even the system has been removed from the power supply.
SAFETY INSTRUCTIONS

12
