Mounting
Mount the bracket to a flat surface capable of supporting 186 lbs. (84.4 kg). Acceptable surfaces include
concrete, drywall, or other nonflammable surface as long as they can support the weight specified. Structural
integrity of the mounting surface is the responsibility of the installer.
The Mounting Bracket comes in three pieces. Align the holes at the center of the top and bottom pieces with the
studs on the middle piece. Use the four nuts to connect the pieces and tighten them. See Figure 3-3.
Figure 3-3 Bracket Assembly

Use M10 or 7/16 in. bolts to attach the mounting bracket to the mounting surface. Use 4 bolts corresponding to
the holes shown in Figure 3-4. In the background, the inverter is visible in gray for alignment purposes. The top
of the mounting bracket is 19.7 in (502 mm) below the top of the inverter. Torque the bolts as necessary to
support the weight, depending on the material of the mounting surface.

Lifting Heavy Object Hazard
Proper lifting technique must be used in order to avoid injuries.
Use a two-man lift to install the Power Head.
Place the Power Head on top of the Wiring Box. Position the Power Head so that it aligns with the Wiring Box.
The Power Head will slide into place, using the metal guide pins to align with the Wiring Box. Use the four M5
bolts to connect the Power Head to the Wiring Box as shown in Figure 3-7. Use two screws on the left side and
the other two screws on the right side. Torque the connections to 20 in-lbs. (2.3 N-m).

Power Connections
Use 90°C minimum rated conductors. Connections are rated for both 75°C and 90°C terminal temperatures.
With longer wire runs, the use of larger conductors than those required by Code can help minimize voltage
drop.

Remove Plastic Shields
The Plastic Shields are a safety feature to protect the user from hazardous conditions when the inverter is
running. These must be removed prior to landing the AC and DC conductors in the Wiring Box.
Remove the DC plastic shield, shown in blue in Figure 3-9.

Installation and Operation Guide SOLECTRIA XGI 1000 (Rev D)
Turn AC Switch to OFF
Verify the absence of AC voltage.
Grid Mismatch
If the grid does not match the requirements of the inverter, the inverter will not start.
Check with your local electric utility before selecting a grid profile.
The system must comply with National Electrical Code ANSI/NFPA 70 and with all local
rules and safety regulations before the inverter can be operated.
3.4 AC Connection
Turn the AC Switch OFF before wiring. The switch is located on the right side of the wiring box, see Figure 2-3.
Transformer Configurations
The inverter must be connected to a transformer that has a grounded Wye configuration on the inverter side (see
Figure 3-12 for correct configuration and Figure 3-13 for incorrect configuration). The neutral conductor is used
by the inverter for voltage sensing and does not carry current. Therefore, the size of the neutral conductor may
be reduced to the same size (not smaller) as the EGC. Acceptable service configurations are depicted in Figure
3-12.
It is permissible to connect the neutral terminal of the inverter to ground inside the inverter wiring box through
the use of a jumper. In this configuration, no neutral conductor is required. If terminated properly this connection
will not impact the function of the inverter or create an unsafe condition. Ultimate approval of such configuration
lies with the authority having jurisdiction (AHJ).
Figure 3-12 Permitted Transformer Configurations
A jumper between Ground and Neutral may be used if:
Use of a jumper is approved by the AHJ (required)
There is no accessible Neutral wire
DOCR-070733-D Page 23 of 86
Installation and Operation Guide SOLECTRIA XGI 1000 (Rev D)
Neutral to Ground Jumper
Do not use a jumper between ground and Neutral if the Neutral conductor is connected.
Using a jumper with the Neutral conductor connected may result in damage and void the
warranty.
Improper Transformer Configuration
Inverter will not run and may have hazardous current.
Connect transformer in specified configurations only (see Figure 3-12)

AC Connection Specifications
The AC connections consist of 3 phases (L1, L2, and L3), ground, and neutral. Conductors must be rated for a
minimum of 600 V. Use conductors in accordance with Table 3-1in addition to local electrical codes.
Table 3-1 AC Connection Specifications
Turn AC Switch OFF before wiring. Wire the AC Connections as shown below. Torque all AC connections
according to Table 3-2 with the 3/16 in (4.75mm) slot torque driver, as shown in Figure 3-14.
Table 3-2 AC Torque Specification
When using aluminum conductors it is important to prepare the conductors properly to prevent oxidation. Follow
the steps below to prepare and landing the wires one wire at a time.
a) Remove the oxidation from the connection area of the aluminum conductors.
b) Immediately apply neutral dielectric grease, such as Noalox, and connect the cable to the terminal.
c) If the connection is not made within 30 seconds of applying the grease, repeat this process as an oxidized
layer may have formed on top of the conductor. This oxidized layer is a poorer conductor than the greased
aluminum.
