AC MAINS POWER CONFI
GURATION
Where AC power is r
eadily available, as is the case at some sites, then a power adaptor can be
used to supply the necessary voltage. Requirements for the power adaptor are that it be
capable of sourcing 1 ampere of current at 5.0 volts DC. For Class I, Div. 2 locations, th
is will
require special consideration to ensure that the rules stipulated by NEC and equivalent
Canadian wiring codes for hazardous locations are strictly adhered to.
AC Power Adapter
The output voltage from the power adaptor will be wired into a smal
l terminal block as illustrated
below. It may be necessary to check with a voltmeter which wire is positive and which is
negative coming from the power adaptor.
Polarity of the terminal block connection will be apparent from the opposite end wire colors
in
that Red is positive and Black is negative. In the event that a reverse connection is made by
accident, no harm will be caused to the electronics aside from the fact that the CNI2 will not
power as expected.

A lithium o
r Alkaline battery pack can be connected to the vacant J1 / J2 power connector to
supply continuous power in the event of AC mains failure. Lithium batteries have a longer
‘shelf

life’
as compared to alkaline batteries
, and are
normally regarded as the su
perior choice
for long term backup applications.
