8.1 Introduction
As a PROFIBUS DP fieldbus adapter card that meets international PROFIBUS fieldbus
standards, the MD‑SI‑DP1 expansion card can improve the communication efficiency
of the AC drive and implement the networking function, enabling the AC drive to be a
slave controlled by the fieldbus master. It can implement PROFIBUS DP
communication.
The following table lists the differences between MD‑SI‑DP1 and MD38DP2.

8.2 Installation
The MD‑SI‑DP1 expansion card is embedded in the MD520 series AC drive. Before
installation, cut off the power supply of the AC drive and wait for about 10 minutes
until the charging indicator of the AC drive becomes off. Then, insert the MD‑SI‑DP1
card into the AC drive and fasten the screws to prevent the signal socket between
boards from being damaged by the pulling force of the external signal cable. "
