This manual is for use by qualified personnel only.
DC Interface
The DC interface (see Figure 1-4 on page 1–7) is located on the right side of the
inverter assembly and serves as the connection interface between the PV array
and the Xantrex GT500. This section houses the PV input terminals (TB3, TB4,
and TB5), DC switch S1, PV ground fault detection circuitry, DC surge arrestor,
solid-state relays, and 48 VDC power supply.
Each DC terminal provides 16 M10 clearance holes with space for 16 cables
(see Table A-5 on page A–5 for torque requirements).
Operator Interface Controls
Operator interface controls are located on the front door of the inverter assembly.
The controls are housed in lockable assemblies and include the following:
•
ENABLE/DISABLE switch. The inverter assembly has an ENABLE/DISABLE switch
located on the left front door, under the keypad, as shown in Figure 1-1 and
Figure 1-8. Under normal operating conditions, the
ENABLE/DISABLE switch is
in the
ENABLE position. Turning the switch to DISABLE initiates an immediate
and controlled shutdown of the Xantrex GT500 and opens both the main AC
breaker and DC switch. The Xantrex GT500 will not restart until the
ENABLE/
DISABLE switch is turned back to the ENABLE position.
• Four-line display and keypad used to manipulate and view system operation
and status. The keypad is comprised of 20 touch-sensitive keys that provide
a means to navigate through the menus and alter user-changeable settings.
