Introduction

1.2Outside Enclosure Overview

The enclosure for the Liqui-tect panel’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 metal enclosures accommodate secure conduit fittings and protect components against external forces and debris.
