Electrical safety instructions
With this product, only use the power cable delivered or dened 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 protecve conductor in the power supply cord. To avoid electric shocks, the protec-
ve conductor has to be connected with the ground of the power network. Before connecng the input or output
connectors of the system, make sure that there is a proper grounding to guarantee potenal free usage. For coun-
tries, in which there is no proper grounding, refer to your local legally safety regulaons for safety use.
DC systems: Every DC system has a grounding connected to the chassis (yellow/green safety banana plug).
Note the characteriscs and indicators on the system to avoid re or electric shocks. Before connecng the system,
carefully read and understand the corresponding specicaons in the product manual.
The inputs are not, unless otherwise noted (CATx idencaon), for connecng to the main circuits of category II,
III and IV. The measurement category can be adjusted depending on module conguraon.
The power cord separates the system from the power supply. Do not block the power cord since it has to be acces-
sible for the users.
Any direct voltage output is protected with a fuse against short-circuits and reverse-polarity, but is NOT galvanically
isolated (except it is explicit marked on the system).
Supply overvoltage category is II.
The system must be connected and operated to an earthed wall socket at the AC mains power supply only (except
for DC systems).
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-circuits and re hazard.
The assembly of the system is equivalent to protecon 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 elec-
tric shock by touching the wiring.
Unless otherwise stated, the maximum input voltage for measuring cards is 70 VDC and 46.7 VPEAK
The electrical installaons and equipments in industrial facilies must be observed by the security regulaons and
insurance instuons.
Ambient safety notices
This product is intended for use in industrial locaons. As a result, this product may cause interference if used in
residenal areas. Such use must be avoided unless the user takes special measures to reduce electromagnec
emissions to prevent interferences to the recepon of radio and television broadcasts.
Do not switch on the system aer transporng it from a cold into a warm room and vice versa. The thereby created
condensaon may damage your system. Acclimase the system unpowered to room temperature.
Avoid operaon in the immediate vicinity of:
– High magnec or electromagnec elds
– Transming antennas or high-frequency generators
Any use in wet rooms, outdoors or in adverse environmental condion is not allowed. Adverse environmental
condions are:
– Moisture or high humidity
– Dust, ammable gases, fumes or dissolver
– Thunderstorm or thunderstorm condions (except assembly PNA)
– Electrostac elds etc.
DO NOT use the system in rooms with ammable gases, fumes or dust or in adverse environmental condions.
