Line Filter (Electromagnetic Compatibility Circuit - EMC) Operations, Checkout and Status /
Error Codes
OPERATION:
The line filter reduces the unintentional conducted emission from the equipment, to a level sufficient to pass regulatory
limits (such as FCC part 15).
The filter is rated at 208/230 volt, 30 amp maximum, 60 Hertz.
NOTE - The 2- and 3-ton inverters have the EMC builtin. The 4- and 5-ton units have an external device (see illustration
below).
NOTE -
A line filter is an electronic filter which is placed between electronic equipment and an external power source in order
to attenuate conducted radio frequency interference (RFI). RFI is also known as electromagnetic interference (EMI).
CHECKOUT:
Voltage
IN
should read the same value as the Voltage
OUT
. With filter isolated from system, resistance between
L1
and
L2
should be the same as resistance between
N1
and
N2
.
STATUS CODES:
None
ERROR CODES:
