Chassis Ground
DANGER:
The unit chassis has to be grounded properly before use. Never operate
the unit without proper grounding. Failure to do so will result in death or serious
injury.

- These guidelines assume you are using the DC supplied cable and fuse sizes recommended in this manual.
If you are using different sizes, refer to the applicable installation code for the DC grounding detail.
- In marine applications, the main AC-DC ground bonding may require galvanic isolators to avoid
galvanic corrosion. Check your local electrical codes (i.e. NEC, UL, ABYC).

AC Input Source
An AC source is usually grid power or an AC Generator. The acceptable AC Input voltage
range and frequency are as shown:

230VAC series
180 - 260 VAC
30 - 100 Hz
An automatic or manual AC source selector switch can be used to switch between
the multiple sources of shore power to the unit. Usually, the AC Main Panel includes
a main circuit breaker that serves as over-current protection and as a disconnect
for the AC shore power supply line. Additional AC circuit breakers serve individual
circuits and one of the AC circuit breakers will serve the unit. During By-Pass mode,
the AC Input source will serve the AC Output Load and also the AC Input current for
the charger when it is used to charge the battery.

- Follow the electrical and/or building code when you choose AC Branch Breaker and AC Input wire Size.
Connect the unit to any AC Input Source
- Smaller size AC Input wire can be used when a lower amperage rated AC Input Circuit Breaker is used
from upstream to feed the unit.
The unit is designed to accept non-Sinewave AC Input Source supplied by a
generator.

AC Hardwire Output
An AC Sub-Panel is recommended to incorporate an AC output circuit breaker and breakers
for individual load circuits. Use the same wire size as used for the AC Input Wire.
