INSTRUCTIONS
1. Run all current carrying conductors through
detector window
A. Use an auxiliary CT if conductors do not fi t. Consult
Factory for CT selection.
2. Mount the detector to a surface if needed.
3. Connect output & power wiring.
A. Use 22 to 14 AWG copper wires.
B. Make sure load matches the output shown on the
detectors’ label.
•
Detectors labeled “xxAC” will only detector
AC.
•
Detectors labeled “xxDC” will only detector
DC.
C. Make sure power supply matches the power input
shown on the label.
4. Test
A. Pressing the “TEST” button tests the detectors
internal circuits. CAUTION: The output and any
connected loads will detector!

All low-current Ground-Fault Detectors 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 detector power isolated from noisy circuits.
2. Do not power the detector with the same circuit which pow-
ers contactors or other high current, inductive loads.
Good design practice and code require that all AC power
systems be grounded. AG Series detectors are designed to
work on grounded AC power systems. They may not operate
properly on ungrounded systems.
