This manual is for use by qualified personnel only.
Wiring Requirements
1. All wiring methods and materials shall be in accordance with the National
Electrical Code ANSI/NFPA 70, European Requirements, as well as all state
and local code requirements (for example, DIN / VDE).
2. The Xantrex GT250 E has a three-phase output.
3. The AC power conductor wiring interfacing with the AC terminals in the AC
Interface Enclosure (-H0) are located at L1, L2, L3. These terminals requires
the use of a crimp-on type ring terminal or compression-type lug. Keep these
cables together as much as possible and ensure that all cables pass through
the same knockout and conduit fittings, allowing any inductive currents to
cancel. For torque values, see Table A-5 on page A–5. See Figure 3-8 on
page 3–9 for the location of these terminals.
4. The AC neutral conductor from the transformer is terminated in the AC
Interface Enclosure (-H0) at the Copper Ground Bar. This terminal requires
the use of a crimp-on type ring terminal or compression-type lug. For torque
values, see Table A-5 on page A–5. See Figure 3-8 on page 3–9 for the
location of these terminals.
5. The AC Control Voltage wiring interfacing with the Control Voltage terminals
in the AC Interface Enclosure are located at -X2 L1, L2 and PE. For torque
values, see Table A-5 on page A–5. See Figure 3-8 on page 3–9 for the
location of these terminals.
6. The DC power conductor wiring interfacing with the DC terminals is
terminated in the DC Interface Enclosure (-H2). These terminals requires the
use of a crimp-on type ring terminal or compression-type lug. Keep these
cables together as much as possible and ensure that all cables pass through
the same knockout and conduit fittings, allowing any inductive currents to
cancel. For torque values, see Table A-6 on page A–5. See Figure 3-9 on
page 3–11 for the location of these terminals.
7. This product is intended to be installed as part of a permanently grounded
electrical system as per the National Electric Code ANSI/NFPA70 and EU
requirements, as well as all state and local code requirements (for example,
DIN/VDE). A copper ground rod must be installed within 3 ft. (1 m) of the
Xantrex GT250 E Enclosure. This is the single point earth ground for the
inverter system. The single point ground for the system is to be made at the
ground bus bar in the AC Interface Enclosure.
8. The equipment grounds on the Xantrex GT250 E are marked with PE.
9. AC overcurrent protection for the utility interconnect (Grid-tie) must be
provided by the installers as part of the Xantrex GT250 E installation.
CAUTION: Fire Hazard
In accordance with the National Electrical Code, ANSI/NFPA 70, connect only to
a circuit
provided with 1200 amperes maximum branch circuit overcurrent protection.
