Usually there is no need to do anything for the EMC filter.
When the leakage current from the connected EMC filter causes problems with the power
supply system, removing screws from terminals [E1] and [E2] could improve the problem.
Note that doing so loses the effect of the EMC filter so that the inverter is no longer compliant
with the EMC standards. To remove those screws, consult your Fuji Electric representative.
For the location of terminals [E1] and [E2], see the arrangement of terminals given in Section
2.3.3.1.
The 230 V class series inverters of 75 HP or above and 460 V / 575 V ones of 150 HP or
above have neither [E1] nor [E2]. If you need to separate the EMC filter from those inverters,
consult your Fuji Electric representative.

Removing the screws from terminals [E1] and [E2] separates the grounding capacitors, decreasing
the leakage current.
 FRN030AR1-2U to FRN060AR1-2U, FRN060AR1-4U to FRN125AR1-4U
FRN060AR1-5U to FRN150AR1-5U
Secure the filter grounding wires to the supports, using the screws removed from terminals [E1] and
[E2].
