Planning

•If the input wiring is dual-input and the output wiring is single-input, the following rules apply: If the input breaker on L1 is greater than 25 A, the wire size must be coordinated for that amperage. If the input breaker on L1 is less than 25 A, the wire size must be coordinated for 25 A. The wire size must not be sized for anything lower than 25 A.

•If both the input and the output wiring are dual-input, the output wiring for each line (L1 and L2) must be calculated separately, following these rules: If the input breaker on the specific line is greater than 25 A, the wire size for that line and its neutral must be coordinated for that amperage. If the input breaker on the specific line is less than 25 A, the wire size for that line and its neutral must be coordinated for 25 A. The wire size must not be sized for anything lower than 25 A.

Size of Wiring Downstream of the AC Output Breaker The wiring used between the AC output breaker and your loads must be sized to match the output breaker.

AC Output Neutral Bonding

The AC source must have its neutral conductor bonded to ground.

Bonding system The Freedom SW 3000 provides a system that automatically connects the neutral conductor of the inverter’s AC output circuit to safety ground (“bonding” it) while the inverter/charger is inverting, and disconnects it (“unbonding” it) when the inverter/charger is connected to external AC power. This system is designed to conform to installation codes that require AC sources such as inverters and generators to have their neutral conductors tied to ground at the source of power in the same way that the neutral conductor from the utility is tied to ground. These same codes specify that the neutral can only be connected to ground in one place at any one time.

Suitability This automatic neutral-to-ground bonding system requires AC input sources with bonded neutral. This will be the case in most situations: in a utility feed, at an external AC hook-up, or a generator with a bonded neutral. If not, have an electrician look into bonding the source’s neutral to ground. See also “AC Input and Output Isolation” on page 23.
