Wiring the Inverter
3–10
975-0466-01-01
5. Loosen the appropriate terminals and insert the wires into the terminals.
a) Connect the protective earth wire to a terminal marked
.
b) Connect the neutral phase wire to the terminal marked L/N. (On older
boards this rightmost AC terminal is marked with ~.)
c) Connect the Active phase L wire to the terminal marked L. (On older
boards this left AC terminal is marked with ~.)
6. Tighten the terminals to a torque of 1.45 to 1.55 Nm (12.84 to 13.71 lbf-in).
7. Allowing the wires an appropriate amount of slack within the wiring
compartment, tighten the cable gland cap nut to a torque of 4 Nm, creating a
tight seal.
8. Re-attach the inverter front panel.
Communications Wiring for Multiple Inverters
Communications wiring between multiple GT Inverters allows information about
each inverter and its associated PV array to be communicated between all of the
inverters in the system. Information about the entire system can be displayed on
any inverter LCD in the system.
For example, in a two-inverter system, if inverter #1 is producing 1500 W and
inverter #2 is producing 2000 W, both inverters display a total system power of
3500 W. The cumulative energy produced by both inverters that day is also
displayed.
You can still view information for an individual inverter in a system. See “To view
unit-specific screens in a multiple unit system:” on page 5–6.
Without communications wiring, each inverter in a system displays information
only for the unit and its associated PV array.
CAUTION
For the inverter to meet regulatory requirements and for weather protection, the
communication ports cover must be installed. If no communications wiring is required,
install the communication ports cover when all DC and AC connections are complete (see
Figure 3-12).
