Installation of optional modules and PC

The optional module (such as fieldbus adapter, I/O extension module and the pulse
encoder interface) is inserted into the optional module slot of the inverter unit control
board (RDCU) and fixed with two
manual for further instructions.

Cabling of I/O and fieldbus modules

Keep unshielded portion as
To nearest PE terminal

Cabling of pulse encoder interface module

Keep unshielded portion as
short as possible

Fibre optic link

A DDCS fibre optic link is provided via the RDCO optional module for PC tools,
master/follower link, NDIO, NTAC, NAIO, AIMA I/O module adapter and fieldbus
adapter modules of type Nxxx. See RDCO User's Manual [3AFE 64492209
(English)] for the connections. Observe colour coding when installing fibre optic
cables. Blue connectors go to blue terminals, and grey connectors to grey terminals.
When installing multiple modules on the same channel, connect them in a ring.
