4-20mA (externally powered) - To use an external power supply, wire the positive lead
from the sensor to the positive terminal on the external power source. Wire the negative lead
from the sensor to a numbered input screw on ISACC. Next, connect the power supply to
ISACC by wiring the negative terminal on the power supply to a common screw on ISACC.

SHIELDED WIRE
ISACC is designed to work in most installations without the need of shielded wire. This does
not apply to wire run in conduit that has other noise-generating conductors such as 60Hz AC.
