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
F4. Failure to do so could
result in such damage,
and/or injury or death.
ç
CAUTION:
Maintain isolation
between analog inputs 2
and 3, and between
analog input 1 and digital
inputs 1 to 4 to prevent a
ground loop. A ground
loop may cause incorrect
readings. Failure to
follow this guideline
could result in damage to
equipment and product.
