CAUTION
The FHC-OAVS has two terminal blocks with terminations numbered identically
(terminations 1 through 16). DO NOT mix these up with each other.
If the FHC-OAVS is not connected as shown, it is not resistant to electrical surges. It
is also susceptible to interference from other equipment.
CAUTION
A separate power supply is required if a 4-20 mA sensor is used.
Failure to follow wiring precautions will result in equipment damage.
