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.
ç
CAUTION:
Maintain isolation
between input 1 and
input 2 to prevent a
ground loop. A ground
loop may cause incorrect
readings, dashes across
the upper display or the
display of error codes.
Failure to follow this
guideline could result in
damage to equipment
and product.

**CAUTION:
Process input does not
have sensor break
protection. Outputs can
remain full on.
