WARNING:
To avoid damage to
property and equipment,
and/or injury of loss of
life, use National Electric
Code (NEC) standard
wiring practices to install
and operate the Series
96. Failure to do so could
result in injury or death.

CAUTION:
Maintain isolation
between input 1 and
input 2 to prevent a
