Chapter 3 – Installation
WARNING! Follow the safety instructions given in this
guide and in the ACS 800 Hardware Manual.
The RMBA-01 is to be inserted into the position marked
SLOT 1 on the drive. The module is held in place with
plastic retaining clips and two screws. The screws also
provide the earthing of the I/O cable shield connected to
the module, and interconnect the GND signals of the
module and the RMIO board.
On installation of the module, the signal and power
connection to the drive is automatically made through a
38-pin connector.
The module can alternatively be mounted on a DIN rail-
mountable AIMA-01 I/O Module Adapter (not available
at the time of publication).
Mounting procedure:
1. Insert the module carefully into SLOT 1 on the
RMIO board until the retaining clips lock the module
into position.
2. Fasten the two screws (included) to the stand-offs.
3. Set the bus termination switch of the module to the
required position.
Note: Correct installation of the screws is essential for
fulfilling the EMC requirements and for proper operation
of the module.
