14 Installation

MiniMate2 and Units Where Internal Mounting is Not

Feasible

An enclosure is recommended for use with ceiling-mounted

environmental units or where internal mounting of the Network

Interface Card is not feasible. Older-generation Deluxe and

Challenger units may require external mounting.

Power Connection for External Enclosures

Power for the OpenComms Network card should be sourced

from the supplied wall-plug transformer. Use field-supplied

wiring to connect the outer terminals on the transformer to the

screw connectors at TB3 on the Network Interface card. A field-

supplied ground wire attaches to the center terminal on the

transformer and connects to the grounding stud in the lower

corner of the enclosure.
