* Per ABYC A‐31: A DC chassis grounding conductor shall be connected from the case of the battery to
the engine negative terminal or its bus, and must not be more than one size under that required for the
DC current carrying conductor and not less than 16 AWG.
Note: This diagram does not illustrate a complete system. Refer to ABYC standards E‐11 AC & DC
electrical system on boats.
IMPORTANT: Install fuses at batteries
per ABYC recommendations.
An Important Note about the DC Output Fuse: DC output wiring is protected by an internally mounted
ATC blade‐type output fuse. The fuse holder is located to the bottom right of the meter on the large
circuit board. To remove the fuse for checking or replacing, remove drip shield, then cover and simply
pinch the fuse between thumb and forefinger and pull firmly downward.
The current limiting circuit of the Phase Three charger should prevent the fuse from blowing under
normal operating conditions. If the fuse blows, this may indicate a reverse polarity hook‐up or an
internal short. If the battery is connected to the charger backwards, the fuse should blow to prevent a
dangerous short circuit, however damage to the internal components is possible, as well. If, after
replacing this fuse, it blows again upon application of power, return the charger to an electronics service
professional or to the factory for a thorough inspection. Always replace the fuse with another of the
