5 Installation Procedure
◆
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 the unit to
different models. Select the proper ground cable from the PROFIBUS-DP Option kit depending
on drive size.
