*1 Due to the characteristics of the triac, some precautions require re-checking before replacement.
For details, refer to Section 3.3 (4) to check if there are any precautions that fall under this category.
*2 Connect a fuse to every external terminal to prevent the external device and module at load short from burnout.
Also, configure an external circuit if fuse blown indication is required.
