AC and DC Disconnect Switches
Both AC and DC Interface Enclosures are equipped with lockout hasps for
personnel safety. The enclosure doors should not be opened while the PV100S
is
operating.
The switch handles and shafts provide a door interlock for both the AC and DC
interface enclosures. The doors cannot be opened when the switch is in the
ON
position.
The DC Disconnect switch is equipped with an auxiliary contact block which
enables the switch to be used as a load break DC disconnect. In the event the DC
Disconnect switch is opened while the PV100S
is processing power from the PV
array, the early-break contact block will signal the CCU2 (Converter Control
Unit 2) to stop processing power prior to the opening DC Disconnect switch.
Additionally, opening the DC Disconnect switch will cause the PV100S to
execute an immediate orderly shutdown, open both the main AC and DC
contactors, and report a PV disconnect fault on the LCD of the UFCU.
Communication Features
The PV100S provides two types of information to the user:
•
system status and/or fault information, and
• data logging information.
System status and fault information can be accessed using the Universal Front
Panel Control Unit (UFCU) or a personal computer using the Xantrex Solar
Graphic User Interface (GUI) software. Data logging requires the use of a PC
using the GUI software.
