DC Disconnects The DC circuit from the battery to the Freedom HF must be equipped
and Over- with a disconnect and over-current device. This usually consists of a
Current Devices circuit breaker, a "fused-disconnect," or a separate fuse and DC
disconnect. Do not confuse AC circuit breakers with DC circuit breakers.
They are not interchangeable. The rating of the fuse or breaker must be
matched to the size of cables used in accordance with the applicable
installation codes. The breaker or disconnect and fuse should be located
as close as possible to the battery, in the positive cable. Applicable codes
may limit how far the protection can be from the battery.
