Potential equalisation
The potential equalisation of the BEKOMAT
®
is implemented through the ground terminals provided. Ensure that
these terminals are properly connected to the protective earth conductor.
Install the potential equalisation cables according to the wiring diagram
4.5. NAMUR interface
To ensure that any problems occurring during device operation are detected quickly, the BEKOMAT
®
is connected
to a NAMUR interface that forwards the fault signals. We recommend connecting the NAMUR interface to a switch
amplifier and sending the signals to a centralised control system.
Install the NAMUR interface according to the wiring diagram 4.2, page 19.
NOTE
Information about NAMUR interface
For additional information regarding the connection of the NAMUR interface, see separate
