This manual is for use by qualified personnel only.
Local Display The Xantrex GT500 includes a local user interface comprised of an
ENABLE/
DISABLE switch, keypad, and four-line, 80-character display.
The Xantrex RS485/Modbus Communications Kit provides remote plant
monitoring, offering a remote interface for operator interrogation of the Xantrex
GT500’s system status, control, and metering/data logging as well as protective
functions within the Xantrex GT500.
Inverter Isolation Transformer
The Xantrex GT500 includes a custom, high-efficiency isolation transformer. The
utility-side windings of the isolation transformer are configured Delta. For the
Xantrex GT500 480 and Xantrex GT500 480 PG, they are rated for a 480 VAC
nominal utility interconnection point. For the Xantrex GT500 600 and Xantrex
GT500 600 PG, they are rated for a 600 VAC nominal utility interconnection point.
Physical Characteristics
The Xantrex GT500 is assembled in two Type 3R, corrosive resistant, powder-
coated enclosures (see Figure 1-1 on page 1–4):
• A transformer assembly (left side) with two access doors that houses the AC
interface compartment and isolation transformer section. See Figure 1-2 on
page 1–5 and Figure 1-3 on page 1–6.
• An inverter assembly (right side) with three access doors that houses the DC
interface compartment and power electronics section (upper and lower
portions). See Figure 1-4 on page 1–7 and Figure 1-5 on page 1–8.
Heaters are provided for both assemblies. The Xantrex GT500 comes in two
models configured for positive or negative grounding. The enclosure doors are
equipped with locks to secure the compartments.
NOTICE
Opening the inverter or transformer assembly’s doors will trigger an orderly
shutdown of the Xantrex GT500.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Never open the inverter or transformer assembly’s doors while the Xantrex
GT500 is running. The Xantrex GT500 produces lethal voltages when
energized or “live.” The assembly doors must remain closed and tightly
latched at all times when the inverter is energized. Follow the “Lock-out and
Tag-out Procedure” on page xi, before opening the assembly’s doors.
Failure to follow these instructions will result in death or serious injury.
