Nerve Kit contents

The contents of the kit are delivered in two separate boxes, a small box and a large box. The small box contains the MFN 100 including the Hardware Installation Guide and a mating connector. The large box has the remaining components of the kit: the mounting plate, the SIMATIC I/O module and the digital I/O terminal block.

A power cord and two network cables are also required to finish the setup.
