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 22-14 AWG copper conductors rated 75°C
minimum. Tighten to 9 inch-pounds.
B. Make sure load matches the output shown on the
detectors’ label.
• Detectors labeled “xxAC” will only switch AC
load.
• Detectors labeled “xxDC” will only switch DC
load.
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 switch!

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
powers 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.

For products intended for the EU market, the following is applicable
to the CE compliance of the product:
The sensor may comply with EN 61010-1 CAT III 600 V max line-to-
neutral measurement category. If insulated cable is used for the primary
circuit, the voltage rating of the measurement category can be improved
according to the characteristics given by the cable manufacturer.
De-energize power before changing setpoint jumper position.
Warning! Risk of Danger
Safe operation can only be guaranteed if the sensor is used for the purpose it
was designed for and within limits of the technical specifi cations. When this
symbol is used, it means you must consult all documentation to understand
the nature of potential hazards and the action required to avoid them.
Warning! Risk of Shock
When operating the senor certain parts may carry hazardous live voltage
(e.g. primary conductors, power supply). The sensor should not be put into
operation if the installation is not complete.
