Intended Use

The intended use of the CAN-CBM-Bridge/2 is the operation as intelligent CAN-Bridge, that links
two independent CAN networks.  
The guarantee given by esd does not cover damages which result from improper use, usage not in
accordance with regulations or disregard of safety instructions and warnings.

● The CAN-CBM-Bridge/2 is intended for indoor use only.
● The operation of the CAN-CBM-Bridge/2 in hazardous areas, or areas exposed to potentially 

explosive materials is not permitted.

● The operation of the CAN-CBM-Bridge/2 for medical purposes is prohibited.

Service Note

The  CAN-CBM-Bridge/2  does not contain any parts that require maintenance by the user. The
CAN-CBM-Bridge/2  does   not   require   any  manual   configuration   of   the   hardware.  Unauthorized
intervention in the device voids warranty claims.

Disposal

Devices which have become defective in the long run have to be disposed in an appropriate way or
have   to   be   returned   to   the   manufacturer   for   proper   disposal.   Please,   make   a   contribution   to
environmental protection.
