A RV AC Disctribution panels with AC
breakers for shore and inverter load
(downstream) circuits E Second Freedom EX 4000
B First Freedom EX 4000 F AC output cable with 3 wires (L1|N|G)
connected to the inverter's AC OUT
terminals (L1|N|G) and to the inverter
load sub-panel's common busses for
L1|N|G. The L1 line can be connected to
a single higher rated circuit breaker
(double the capacity of the source circuit
breaker).
C AC output cable with 3 wires (L1|N|G)
connected to the inverter's AC OUT
terminals (L1|N|G) and to the inverter
load sub-panel's common busses for
L1|N|G. The L1 line can be connected to
a single higher rated circuit breaker
(double the capacity of the source circuit
breaker). G AC input cable with 3 wires (L1|N|G)
connected to the inverter's AC IN
terminals (L1|N|G) and to the source
panel's common busses for L1|N|G.
D AC input cable with 3 wires (L1|N|G)
connected to the inverter's AC IN
terminals (L1|N|G) and to the source
panel's common busses for L1|N|G.

Do not connect to the inverter’s L2
terminals in both units.
Parallel Stacking Operation
When two inverter/chargers are stacked for parallel operation, Search Mode must be enabled. For information on Search Mode
setting, see the Freedom EX 4000 Owner's Guide (document number: 975-0999-01-01).
