Installation 22
The MMI requires power and Ethernet communications from the FCM. The power connections can be made
with AC or DC supplies when made to the appropriate terminals. The Ethernet connection is made between
the THMI module and the configured board set in the FCM enclosure.

The THMI module’s touch-screen user interface is standard on the ST, N4, and QT models of the
AccuLoad IV. It connects to the A4M board using an Ethernet cable.
