All extension cards are of the same dimensions (108 mm × 39 mm) and can be installed in the same way.

Following the following operation principles when installing or removing an extension card:

1.    Ensure that no power is applied before installing the extension card.

2.    The extension card can be installed in any one of the SLOT1, SLOT2, and SLOT3 card slots.

3.    VFDs of 05R5G/7R5P or below can be configured with two extension cards, VFDs of 7R5G/011P or higher can be configured with three extension cards.

4.    If interference occurs on the external wires after extension cards are installed, change their installation card slots flexibly to facilitate the wiring. For example, the connector of the connection cable of the DP card is large, so it is recommended to be installed in the SLOT1 card slot.

Figure A–1 shows the installation diagram and a VFD with extension cards installed.
