Installing and Wiring Option Boards

Installation
When installing an option board, turn OFF the input power supply and wait for 5 minutes or longer. Remove
the terminal cover and confirm that the CHARGE indicator inside the Inverter is not lit. After confirming that
the CHARGE indicator is not lit, remove the Digital Operator and front cover and then install the option
board.
The side of the front cover of the Inverter for 200/400 V Class 0.4 to 3.7 kW can be cut out as described in
Fig
2.22
to make wiring of the option board easy. If the side of the front cover is cut out, the protective structure
will be open chassis (IEC IP00).
Refer to documentation provided with the option board for actual mounting instructions for option slots A, C,
and D.
Preventing C and D Option Board Connectors from Rising
After installing an option board into slot C or D, insert an option clip to prevent the side with the connector
from rising. The option clip can be easily removed by holding onto the protruding portion of the clip and pull-
ing it out.
Remove the option clip before installing an option board into slot C or D. The option board can not be
installed completely and may not function properly if it is installed with the option clip attached.
