 Installing the Option Unit
Remove the front cover of the drive before installing the CC-Link 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
CC-Link 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 CC-Link Option cover in step 8.
