> 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 V
AC
or >35 V
DC
! 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 V
DC
and 46.7 V
PEAK
.
> 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.
