lines by nearby radio transmitters or wireless products. EMI filters are incorporated to reduce noise from Electromagnetic
Interference (EMI) produced by such items as electric motors, switching power supplies and lightning. The benefit of these filters
can be seen on video products or audibly by reducing static pops and external signal interference.

storms or utility power plant grid switchovers. The amount of energy that can be injected into the power system can be immense
with voltages reaching 6KV or amperage peaks of 3000A. These spikes are very fast and usually only last for a very short period of
time. To protect against this potential problem, incoming AC Mains have special suppression circuitry to eliminate the unwanted
energy. This circuitry is very fast and can suppress unwanted energy within a nanosecond, while sustaining the suppression up to 2
milliseconds, thus ensuring virtually trouble free protection.

128VAC and up. They can be caused by fluctuations in the utility company's power lines or industrial equipment turning on
and off, and are on the same power leg of the building's incoming AC.

from the ECM modules and will inform you of potentially damaging voltages. If the AC Mains voltage is between 128VAC
and 132VCA or 107VAC and 101VAC the display will flash an error code indicating a potential fault has occurred and you should
check sensitive equipment. If an extreme voltage swing occurs above 128VAC or below 101VAC, the Extreme Voltage Shutdown
(EVS) protection circuit will automatically turn all remote ECM modules off until the system is manually reset. The EVS feature can
be defeated if required via the ECS-6RM EVS bypass switch.
