Connect the Control Panel cable to terminal X19 of the NAMC-11, or
with NAMC-03 board to terminal X28 of the NIOC board (X300 of the
NIOCP board).

The pulse encoder shall be insulated electrically from stator or rotor to
prevent forming of current path through the pulse encoder. The usual
coupling-type encoder must have an electrically insulating coupling.
When a hollow-shaft type pulse encoder is used, the insulation can be
implemented by insulating the ball joints of the engaging arm, or
insulating the bar of the engaging arm. Shield of the encoder cable
should be insulated from the encoder frame. See Appendix B for
earthing of the other end of the encoder cable shield.
This section gives general installation instructions for Drive Window 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.
The module should be installed on the DIN mounting rail inside the
cabinet. Follow the instructions given in the Mechanical Installation
chapter of the module manual.
The 24 V d.c. supply for one optional module is provided by the NIOC/
NIOCP board of the converter (NIOC: terminal X23, NIOCP: terminal
X4). The location of the NIOC/NIOCP board is shown in the
dimensional drawings ( Appendix B ).
