Mounting Procedure
1, 2, 3... 1. Be sure to turn OFF the main Inverter power supply,
wait at least 1 minute (at least 3 minutes for 30-kW-or-
higher Inverters), remove the front cover of the Inverter,
and make sure the charge indicator is not lit.
2. The PG Speed Control Card is an option A. Mount the
Card in the option-A location as shown in the diagram
below.
3. Insert the spacer that is provided into the spacer mount-
ing hole located on the mounting base of the Inverter.
There are 2 holes located on 3.7-kW-or-lower Inverters.
Insert the spacer in the hole on the 7CN side. Be very
careful because spacers cannot be removed if they are
inserted in the wrong hole.
4. Proceed in order with steps
A
and
B
in the enlarged
view below. Align the PG Speed Control Card and the
supports, make sure the connector on the Card is
aligned with the option-A connector, and then push the
spacer through the spacer mounting hole on the Card.

)
Make sure the 4CN positions are properly aligned, and
push the spacer through the hole until it clicks into
place.
5. Connect the ground wire of the Card to the FG terminal
12(E) on the Inverter control circuit board.
