Power Supply Notes
All low-current Ground-Fault Sensors are sensitive devices
that require reasonable care in system design to avoid false
trips caused by high electrical noise levels. Keep in mind that
the best way to reduce noise in a system is to suppress it at its
source.
1. Keep the sensor power isolated from noisy circuits.
2. Do not power the sensor with the same circuit that
switches contactors or other high current, inductive loads.
System Grounding
Good design practice and code require that all AC power
systems be grounded. AG Series sensors are designed to
work on grounded AC power systems. They may not operate
properly on ungrounded systems.

Quick "How To" Guide
1. Run all current carrying conductors
through sensor window
A. Use an auxiliary CT if conductors do not fit. Con-
sult Factory for CT selection.
2. Mount the sensor to a surface if needed.
3. Connect output & power wiring.
A. Use up to 14 AWG copper wires.
B. Make sure power and load matches those shown on
the senors' label.
4. Test
A. Pressing the "TEST" button tests the sensors inter-
nal circuits. CAUTION: The output and any con-
nected loads will switch!
