Important notes for using the BP104
•The BP104 is only suitable for extra-low voltages, please observe the relevant regulations!
•Only use an electrical isolated power supply unit (with CE).
•All accessible pins are electrostatic devices. Workplace must be conductive during installation.
•The construction height depends on the height of the used measuring amplifiers.
•The BP104 must only be used in closed housings (for reasons relating to EMC).
•For cleaning use water and mild detergent only.
•The device is designed to be maintenance-free. To calibrate the board it must be sent in to bmcm.
•The sensors or signals are connected at the input plug. Make sure to use shielded cables.
•For a good noise suppression connect the shield to ground at one end only. Close open inputs if possible.
•The BP104 ground is electrically connected to the next connected measuring system and therefore also to the
ground of the PC, which is usually also connected to earth. Be sure to avoid earth and ground loops during sensor
wiring, since they will cause measuring errors!
•The device must not be used for safety-relevant jobs. With the use of the product the customer becomes manufac-
turer by law and is therefore fully responsible for the proper installation and use of the product. In 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
disposed according to the WEEE directive or can be returned to bmcm at your own expense.
