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. AGL 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 fi t. Consult
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 internal
circuits. CAUTION: The output and any connected
loads will switch!
