Power Supply Notes
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.
System Grounding
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.
