Introduction
Overview
The MX350 is a modular control and monitoring system designed specifically for low-
voltage transfer switch application. The MX350 provides the following key benefits.
• Flexible control and communication options to suit any low-voltage transfer switch
application.
• Small footprint.
• Modular design reduces the number of spare components for maintenance and
testing.
• Integrated pushbuttons and LED indicators reduce external components and wiring.
• DIN rail and Panel Mounting.
• Multiple communication protocols allows simple integration into monitoring and
control systems.
• Graphical control panel interface provides local control and access to system
information.
• Automation FlexLogic™ with interlocking and programmable logic control.
Cautions and warnings
Before attempting to install or use this device, it is imperative that all caution and danger
indicators in this manual are reviewed to help prevent personal injury, equipment damage,
or downtime. The following icons are used to indicate notes, cautions, and dangers.
