1.2 Safety instructions
Be sure to observe the following instructions:
• Ensure that the card is very well ventilated in the PC case, as the output drivers can get up
to 100 °C hot under full load.
• It is essential to avoid touching cables and connectors etc. inside the PC with the board.
• Never expose the unit to direct sunlight during operation.
• Never operate the unit near sources of heat.
• Protect the unit from moisture, dust, liquids and vapours.
• Do not use the unit in damp rooms and never in potentially explosive areas.
• Repairs may only be carried out by trained, authorised personnel.
• When commissioning the unit, please observe the installation regulations and all relevant
standards (incl. VDE standards), especially when operating with voltages greater than 42 V.
• We recommend connecting unused inputs to the corresponding reference ground to avoid
crosstalk between the input channels.
• Always disconnect your field wiring from the power source before making or breaking cable
connections to the board.
• Make sure that no static discharge can take place via the device when handling the card.
Follow the standard ESD protection measures (see also chapter 2.1 on page 9).
• Never connect the units to live parts, especially not to mains voltage.
• Precautions to avoid unforeseeable misuse must be taken by the user.
