5 Installation Procedure
Installing the Option Unit
Remove the front cover of the drive before installing the EtherNet/IP 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 EtherNet/IP 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 EtherNet/IP
Option cover in step 8.
