Installation
WARNING! Before installation, switch off the drive power supply. Wait for five
minutes to ensure that the intermediate circuit is discharged. Switch off all
dangerous voltages connected from external control circuits to the relay output
terminals of the drive.
WARNING! Do not touch the printed circuits. They are extremely sensitive to
electrostatic discharge.
Master/Follower link
The ring configuration can be used in most applications. A parallel connection can
also be implemented by using a branching unit. (For more information, contact your
local ABB representative.)
Handle the fibre optic cables with care. Do not touch the ends with bare hands, as
fibre optic cables are extremely sensitive to dirt.
Note: For best results, all RDCO boards on the link should be of the same type.
T = Transmitter; R = Receiver; RMIO = I/O and Control Board.
Please note that channels CH0/CH2/CH3 are located on the optional RDCO-0x board.
