Introduction

1.5Outside Enclosure Overview

The enclosure for the Universal Monitor’s controller board comes in two sizes:

•The large enclosure is designed to accommodate the Transformer Module and future compo- nents, in addition to the controller board.

•The small enclosure is built to hold the controller board only.

Both enclosures are 2-3/4" deep.

Both enclosures have a built-in liquid crystal display (LCD) and a key lock, as shown in the example below. The enclosures are made of metal to accommodate secure conduit fittings and protect compo- nents against environmental debris.
