Xantrex Technology PV100S-208 manual Communication Features, AC and DC Disconnect Switches

Introduction

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 opening the 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.
