4.9 Utility Grid (Source) Port Wiring
The GTIB-30 is a Grid-tied inverter and the utility grid must be connected to the unit.
Wire requirements for this wiring are provided in Section 4.5.1.
Ensure that the utility is disconnected when connecting utility wires. Never attempt
to connect live wires. Use standard lockout procedures to ensure the utility supply
cannot be reconnected during installation.
The utility wires must be fed into the enclosure. Once inside the enclosure, the utility
wires must be connected to the four terminal blocks marked as
U
,
V
,
W
, and
N
(if
used) as shown below. U, V, and W, are live and N is Neutral.
Figure 25: Grid port wiring connections.
Wires should be stripped a minimum of .55” (14mm) before inserting into terminal
blocks.
It is important to ensure that the neutral wire (if used) is connected to
N
and not
U, V,
or
W
. A multi-meter and Table 2 can be used to determine which wire is the neutral
wire should this information not be available. Ensure that supply is disconnected
again after measurements are made before continuing with installation.
