Safety
Wiring Requirements
1. All wiring methods and materials shall be in accordance with the National Electrical Code ANSI/NFPA 70, as well as all state and local code requirements.
• Use copper conductors only with an insulation rating of 90 °C. The
optional Fused Combiner (GTFC), if insta l led, requires the use of copper conductors only with a maximum insulation rating of 75°C.
2. The GT100 has a three-phase, four wire output.
3. The GT100 is interfaced with the AC utility grid at TB1 (TB1-A, TB1-B, TB1-C and TB1-N), located in the lower left side of the enclosure. These terminals require the use of a UL-approved crimp-on type ring terminal or a UL-approved compression-type lug certified for use with the chosen interface cables. 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 1-3 on page 1–5 for the location of these terminals.
4. The AC neutral terminals (H0 and X0), shall be left floating (not connected) on both the utility and inverter sides of the isolation transformer. See page 2– 4 for details.
5. The GT100 is interfaced with the DC photovoltaic array at either the Fused Combiner (GTFC) or TB3, as well as TB4 and TB5 (PV GND), located in the lower right side of the enclosure. Do not connect the grounded power conductor from the PV array directly to TB5 (PV GND); doing so will bypass the ground fault detector and violate the NEC. The TB3, TB4, and TB5 terminals require the use of a UL-approved crimp-on type ring lug or a UL­approved compression-type lug certified for use with the chosen interface cables. The Fused Combiner assembly includes box style connectors for cable termination. 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 acceptable torque values for the box style connectors and the TB3, TB4, and TB5 terminals, see Table A-6 and Table A­7 on page A–5. See Figure 1-5 on page 1–8, Figure 1-6 on page 1–9, Table 1­1 on page 1–8, and Table 1-2 on page 1–9 for the location and polarity of these terminals.
6. This product is intended to be installed as part of a permanently grounded electrical system as per the National Electrical Code ANSI/NFPA 70, as well as all state and local code requirements. A copper clad earth grounding electrode must be installed within 3 ft. (1 m) of the GT100 enclosure to ensure compliance with FCC Part 15, Class A. The AC ground bus bar (TB2), located in the lower left side of the GT100 enclosure, must be used as the single point connection to the earth grounding electrode for the inverter system.

8. AC overcurrent protection for the utility interconnect (Grid-tie) must be provided by the installers as part of the GT100 installation.
CAUTION: Fire Hazard
In accordance with the National Electrical Code, ANSI/NFPA 70, connect only to a circuit provided with 400 amperes maximum branch circuit overcurrent protection for model GT100­208-NG and GT100-208-PG, and only to a circuit provided with 200 amperes maximum branch circuit overcurrent protection for model GT100-480-NG and GT100-480-PG.
Inverter Isolation Transformer
The GT100 includes a custom, high-efficiency, isolation transformer. The utility side windings of the isolation transformer are configured W ye and must match the voltage at the utility inter-tie. The GT100 is a balanced, three-phase, current­sourcing inverter and only operates with the presence of a stable utility voltage. The transformer is supplied with a neutral connection on both the Primary and Secondary windings. Connection of these neutral terminals will affect the operation of the GT100 and must be left floating or disconnected. Single-phase, grounded loads which may be present between the transformer and utility, will maintain their existing ground reference at the utility distribution transformer.
Safety
CAUTION: Equipment Damage
If the Isolation Transformer neutral (H0 and X0) terminals are tied to ground, they may cause irreparable damage to the GT100. Check local regulations for their requirements regarding the connection of these neutrals.
Operational Safety Procedures
Never work alone when servicing this equipment. A team of two is required until the equipment is properly de-energized, locked-out and tagged, and verified de­energized with a meter.
Thoroughly inspect the equipment prior to energizing. Verify that no tools or equipment have inadvertently been left behind.
Lockout and Tag
Safety requirements mandate that this equipment not be serviced while energized. Power sources for the GT100 must be locked-out and tagged prior to servicing. A padlock and tag should be installed on each energy source prior to servicing.
