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.
