Connecting and Setting Up the MicroMaster Series 3 Drive

Connecting the MicroMaster 3 Drive
You can use the standard PROFIBUS cable and connectors to connect the S7-200 to the
MicroMaster Series 3 (MM3) drive. See Figure 11-5 for the proper cable bias and termination of
the interconnecting cable.
Caution
Interconnecting equipment with different reference potentials can cause unwanted currents to
flow through the interconnecting cable.
These unwanted currents can cause communications errors or damage equipment.
Be sure all equipment that you are about to connect with a communications cable either shares
a common circuit reference or is isolated to prevent unwanted current flows.
The shield must be tied to chassis ground or pin 1 on the 9-pin connector. It is recommended
that you tie wiring terminal 2--0V on the MicroMaster drive to chassis ground.
