Residual dangers
The scope of supply and performance of the CANHEAD system only covers a
small area of measurement technology. In addition, equipment planners,
installers and operators should plan, implement and respond to the safety

minimize remaining dangers. On-site regulations must be complied with at all
times. There must be reference to the remaining dangers connected with
measurement technology.
Safety rules
The supply connection, as well as the signal and sense leads, must be
