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.
•
Keep the sensor power isolated from noisy circuits.
•
Do not power the sensor with the same circuit that switches con-
tactors or other high current inductive loads.
System Grounding
Good design practice and code require that all AC power systems
be grounded. The EGFL Series sensors are designed to work on
grounded AC power systems. They may not operate properly on
ungrounded systems.
