ABB ACA 6 Series - Installation of Optional Modules

Chapter 3 – Electrical Installation
3-38 ACA 6xx Sections and ACS/ACC 6x7 (132 to 3000 kW) Frequency Converters
Installation of
Optional Modules
This section gives general installation instructions for the DriveWindow
PC tool and ACx 600 optional modules, such as fieldbus adapters, I/O
extension modules and the pulse encoder interface. Connection
examples are given at the end of the section.
Placement The module should be installed on the DIN mounting rail inside the
inverter unit cabinet, located on the inside of the left-hand side cabinet
wall. The DIN rail of ACx 6x7 units is located in the Auxiliary Control
Unit (ACU). Follow the instructions given in the Mechanical Installation
chapter of the module manual.
Power Supply
for the Module
The 24 V d.c. supply for one optional module is provided by the NIOC
board of the inverter module (terminal X23). The NIOC board is
assembled into the NDCU control unit, mounted on a DIN rail inside the
inverter unit cabinet or in the Auxiliary Control Unit (ACx 6x7 units).
Fibre Optic Link Optional modules are connected via a DDCS fibre optic link to the
NAMC board or NDCO board (both mounted on top of the NIOC
board). The terminals to which the cables are connected on the NAMC/
NDCO board are given in the table below. Channel CH1 is on
NAMC-11/51 board. Channels CH0, CH2 and CH3 are on the NDCO
board. The NAMC-03 and NAMC-21/22 boards include channels CH0
to CH3.
The NAMC 11/51 board is used with ACx 6x7 units. The NAMC-21 and
NAMC 22 boards are used with ACS 600 MultiDrive: NAMC-21 with
AC 80 and NAMC 22 with the fieldbus.

DriveWindow Light is connected via an NPCU RS-232/485 converter to the panel
connector on the cover (or to modular jack X19 on the NAMC-11/51 board).
