Cabling Of I/O And Fieldbus Modules; Cabling Of Pulse Encoder Interface Module; Fiber Optic Links - ABB ACS800-17LC Hardware Manual

Cabling of I/O and fieldbus modules

Keep unshielded portion as
short as possible
To nearest PE terminal

Cabling of pulse encoder interface module

Keep unshielded portion as
short as possible
Note 1: If the encoder is of unisolated type, ground the encoder cable at the drive
end only. If the encoder is galvanically isolated from the motor shaft and the stator
frame, ground the encoder cable shield at the drive and the encoder end.
Note 2: Twist the pair cable wires.

Fiber optic links

DDCS fiber 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 fiber 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.
