Connecting the DC Wiring
The GT Inverter is equipped with four PV quick connects (two positive, two
negative) for connecting up to two PV strings. The GT5.0-SP model has six PV
quick connects for connecting up to three PV strings.
Figure 3-1
PV Quick Connect Locations
WARNING: Shock hazard
Whenever a PV array is exposed to sunlight, a shock hazard exists at the output wires or
exposed terminals. Cover the PV arrays with opaque material before commencing any
wiring and open all disconnect switches between the array and the inverter.
WARNING: Shock hazard
Before wiring the GT Inverter, ensure the
main breaker
in the primary utility breaker box
is switched OFF. Switch this breaker ON only after all wiring is completed as instructed in
the procedures.
WARNING: Fire hazard
For GT5.0-SP models, if three PV strings are connected, internal DC fuses must be
installed and the two positive internal DC wires must be relocated from their
factory-installed connection points to connection points in line with the DC fuse clips. The
third positive DC wire must remain connected in line with the DC fuse clip as it came
from the factory. See Figure 3-2. Without proper fusing, a fire hazard can exist if a
short-circuit condition occurs in one PV string.
