Basic Installation Procedures
21 Freedom SW-RVC Installation Guide
n
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 volts AC, 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 20 amps and Line 2
is supplying 15 amps, the current in the neutral will
be 35 amps.
AC Output The output voltage on Freedom SW-RVC
inverter/chargers is 120Vac. Both configurations
are supported - Single Input and Single Output line
(SI-SO) configuration and Dual Input and Dual
Output lines (DI-DO) configuration.
AC Loads The Freedom SW-RVC is intended to power loads
consisting of 120 volts AC appliances.
In Invert mode, the Freedom SW-RVC connects
L1 and L2 output lines together to provide 120 volts
AC 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 volts AC appliances can
be connected to the Freedom SW-RVC output.
AC
Disconnect
and Over-
Current
Protection
Device To meet CSA, UL, and electrical code
requirements, and to protect system wiring, the AC
inputs and outputs of the inverter/charger must be
provided with overcurrent protection on both the
AC input and output. This protection may be a
circuit breaker or a fuse with a disconnect device
(for simplicity the following refers to breakers).
Refer to your applicable installation codes and the
following requirements:
AC Input
Protection The breakers protecting the AC input of the
Freedom SW-RVC must be approved for use on
120 volts AC branch circuits, and must be located
in each Line. The breakers must be rated as shown
below:
