Use the plug-in option dedicated for the FR-A100EXCELLENT.
To avoid an incorrect installation, the connector position for the plug-in option and the FR-A100EXCELLENT is different from the one for the FR-A100 plug-in option.
Do not install an incorrect option forcibly because doing so breaks the plug-in option unit.

The functions of the FR-EPB to FR-EPE are the same as those of the conventional FR-APB to FR-APE options.
For the FR-A100EXCELLENT, the FR-EPG and FR-EPH options are added.
