Important

The suitable fuse rating for an inline fuse and thermal breaker is dependent on the number of devices you are connecting. When connecting multiple Alpha displays in a series (up to 4 maximum), ensure that the fuse rating is appropriate for the total power consumption of all daisy-chained Alpha displays in your system.
