Important Notes for Using the PC104-AD16
•
The PC104-AD16 is only suitable for extra-low voltages - please observe the relevant regulations! Only use the
card in closed housing. ESD voltages at open lines may cause malfunction.
•
All accessible pins are electrostatic devices. Workplace must be conductive during installation.
•
Signals are connected at the analog connector – preferably use shielded cables. For best possible interference sup-
pression, connect shield at one end only. Close open inputs if necessary.
•
The ground of the PC104-AD16 and the chassis are electrically connected to the chassis of the PC, which is usu-
ally also connected to ground. Be sure to avoid ground loops since they will cause measuring errors!
•
Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.
•
The product must not be used for safety-relevant tasks. With the use of the product, the customer becomes manu-
facturer by law and is therefore fully responsible for the proper installation and use of the product. In the case of
improper use and/or unauthorized interference, our warranty ceases and any warranty claim is excluded.
Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly dis-
posed according to the WEEE directive or can be returned to bmcm at your own expense.
