AC Components

AC Input

AC input to the Freedom SW 3000 can be supplied from a split-phase or
dual-input AC source such as the utility grid (power company), a generator,
or the output of a transfer switch. The Freedom SW 3000 can be operated
from the following types of 120 volt 60 Hz AC sources:
• Split phase: This source type has two lines, one neutral, and one
ground. The two 120 VAC lines are 180 degrees out of phase with each
other, so that the two voltages total to 240 VAC. The voltage between
each line and neutral is still 120 VAC, and the voltage between the
neutral and ground is approximately zero.
Because the two lines are out of phase, the currents from each line
subtract in the neutral, and the neutral current will be approximately
zero if the loads are equal. For example, if Line 1 is supplying 20A and
Line 2 is supplying 15A, the current in the neutral will be 5A.
• Dual input: This source type has two line inputs, one neutral, and one
ground. Unlike the split-phase type, the two lines are in phase (not out
of phase), and must come from the same source. The voltage between
the two lines is zero. The voltage between each line and the neutral is
120 VAC, and the voltage between the neutral and ground is
approximately zero.
Because the two lines are in phase, the currents from each line add
together in the neutral. For example, if Line 1 is supplying 20A and
Line 2 is supplying 15A, the current in the neutral will be 35A.

AC Output

AC output from the Freedom SW 3000 is 120 VAC, and can be wired as
single output or dual output.

AC Loads

The Freedom SW 3000 is intended to power loads consisting of 120 VAC
appliances.
In Invert mode, the Freedom SW 3000 connects L1 and L2 output lines
together to provide 120 VAC to loads on either line. In AC Bypass mode,
the source connected to the AC input is passed through to the load. Because
of the way invert mode operates, only 120 VAC appliances can be
connected to the Freedom SW 3000 output.
IMPORTANT:
The Freedom SW 3000 is designed to be connected to AC
sources that energize both L1 and L2 inputs, and cannot be powered by
single-phase input where only one of L1 or L2 is energized. To connect the
Freedom SW 3000 to a single-phase AC supply, install an appropriate
transfer switch to energize both L1 and L2 inputs. Consult a qualified
installer for further support.
ELECTRICAL SHOCK HAZARD
Do not connect 240 VAC loads to the Freedom SW 3000 outputs. Doing
so may result in 120 VAC on exposed parts of the appliance.
Failure to follow these instructions will result in death or serious
injury.
