Mounting

The RCNA-01 is to be inserted into its option slot inside 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 control board of the drive.
On installation of the module, the signal and power connection to
the drive is automatically made through a 34-pin connector.
Mounting procedure:
• Insert the module carefully into its position inside the drive until
the retaining clips lock the module into position.
• Fasten the two screws (included) to the stand-offs.
• 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.
