Introduction
Auxiliary Control Interface
Communications Circuit
1–6
The GT100 has provisions within the AC Interface for installing auxiliary control
signals that include a remote Emergency Stop and a remote Enable/Disable signal.
Auxiliary Control via the remote Enable/Disable signal is advantageous for
coordination of the GT100 at specific installations where a pre-existing back-up
emergency generator is present.
Two separate dry contact circuits at the TB7 terminal are used for remote control
of the input signals. Circuit termination and signal type are identified in Table A-8
on page A–6.

The GT100 can be remotely accessed through an RS232 serial port or through an
RS485/Modbus connection. Xantrex offers modems that can be connected to the
RS232 port for remote monitoring. The remote user has the ability to control and
monitor the status of the inverter through this connection.
Alternatively, a user selectable RS485/Modbus connection is also available for
remote plant monitoring. The CCU2 Controller board within the GT100 may be
configured for RS485 serial communication using the Modbus protocol. This
enables users to monitor and control the inverter from a dedicated plant wide
monitoring system.
