Inverter AC Connections
GRID and GEN inputs
To make the connections to the
Radian inverter:
(See Figure 33 on page 38.)
1.
Choose the AC circuit breaker set
at the top and designate it as the
inverter AC output disconnect.
Install a wire from the black TBB of
the AC output circuit (as shown in
Figure 28) to the right side of the
upper
pole of that disconnect.
2.
Install a wire from the red TBB of
the AC output circuit to the right
side of the
lower
pole on the
same disconnect.
3.
Install wires on the left side of
each pole of the disconnect.
Connect these wires to the
appropriate L1 and L2 output
terminals on the Radian inverter.
4.
Choose the third AC circuit
breaker from the top and
designate it as the disconnect for
one AC source (Grid or Gen).
Install a wire from the black TBB of
the appropriate source circuit (as
shown in Figure 28) to the left side
of the
upper
pole of that
disconnect.
5.
Install a wire from the red TBB of
the source circuit to the left side of
the
lower
pole on the same
disconnect.
6.
Install wires on the right side of
each pole of the disconnect.
Connect these wires to the
appropriate L1 and L2 input
terminals on the Radian inverter
(the terminals labeled either GRID
or GEN).
7.
If a second AC source is present,
repeat these steps using the
second circuit breaker.
8.
Install a wire on the inverter’s NEU
terminal and connect it to the
GSLC’s neutral TBB (as shown in
Figure 28).
Only one neutral
connection is required.
