Prior to Installing the Option Unit
Prior to installing the PROFIBUS-DP Option, wire the drive and make necessary connections to the drive terminals.
Refer to the YASKAWA AC Drive Quick Start Guide for information on wiring and connecting the drive. Verify that the
drive operates normally without the option installed.
Installing the Option Unit
Remove the front cover of the drive before installing the PROFIBUS-DP Option. Follow the directions below for proper
installation.
1. Switch off the power supply to the drive.
DANGER! Electrical Shock Hazard - Do not connect or disconnect wiring while the power is on. Failure to comply will result in death
or serious injury. Before installing the PROFIBUS-DP Option, disconnect all power to the drive. The internal capacitor remains charged
even after the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To
prevent electric shock, wait at least five minutes after all indicators are off and measure the DC bus voltage level to confirm safe level.
2. Remove the front cover. The original drive front cover may be discarded because it will be replaced by the
PROFIBUS-DP Option cover in step 7.

3. Remove the bottom cover and connect the PROFIBUS-DP Option ground cable to the ground terminal.

Note: The four different ground cables packaged with the PROFIBUS-DP Option connect to different models. Select the proper ground
cable from the PROFIBUS-DP Option kit depending on drive size.
