3.1 Power supply connector
To
the COVAL Local Bus, it is mandatory to use the M8 termination provided with
end
any LEMCOM island (to be ordered separately for customized configuration). This specific
interface must be inserted in between the last Secondary module back connector and the
power supply cable. It ensures a good reliability of the COVAL Bus communication
(integrated 120 ohms termination resistor) and separates the communication lines from the
power supply.
The termination is not required for a standalone master module used without any
secondary modules.
