Installation Of Optional Modules And Pc; Cabling Of I/O And Fieldbus Modules; Cabling Of Pulse Encoder Interface Module; Fibre Optic Links - ABB ACS800-37-0060-3 Hardware Manual

Installation of optional modules and PC

Optional modules (such as fieldbus adapters, I/O extension modules and pulse
encoder interfaces) are inserted into the optional module slot of the RMIO boards
(built in the RDCU drive control units) and secured with two
RMIO boards are described on page 35. See the appropriate optional module
manual for information on the cable connections.

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 links

DDCS fibre optic links are provided by RDCO modules (optionally installed on the
RDCU control units) for PC tools, master/follower link, NDIO, NTAC, NAIO, AIMA I/O
module adapter and fieldbus adapter modules of type Nxxx. See the 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.
