Section Safety
DANGER
Electrical Shock Hazard
Power to the drive must be shut off when installing the CC-Link Option.
Even though the power has been shut off, voltage still remains in the drive’s DC bus. Wait
before removing the front cover once the drive has been turned off.
The CHARGE light on the drive will go out after voltage in the DC bus drops below 50 V,
at which point it is safe to remove the front cover.
Due to the risk of electric shock, be sure that all LEDs have gone out and that the DC bus
voltage has reached a safe level prior to performing any work on the drive.
