MFC010 Interface Manual 11
Because the connection to the bus requires exposing the signal wires, the connection to the main bus
should be made within a suitable EMI shielded enclosure. This connection should include the “Common”
signal connection, the power supply connection (if a suitable one is provided by the bus), and the drain
wire when available. Each of the cable screens must be properly terminated to the enclosure by means of
appropriate EMC cable glands. For example:
If the Bus does not provide a s uitable power supply for the MFC010, a separate suitable power supply
connection should be made at this point.
An RS485 Repeater can be used to extend the length of the Bus and the number of slave devices that are
attached t o t he bus ( refer t o t he f igure bel ow). H owever, if the bus is extended in such a fashion,
termination and polarization networks should be fitted according to the same rules as used for the main
bus (see descriptions above).
