Important: The internal EMC filter (input filter) is a
factory-installed option on frame B drives. If the option
is installed, the drive cannot be used on a non-solid
ground power source.
To verify: an extra “R, S, T” terminal block is present if
the option is installed (as shown). Additionally, the 13th
character of the nameplate catalog number is “A” (see
page 31
).
Solid ground
Verify that the jumpers at both locations are installed
(JP2/JP3 and JP5/JP6).
Non-solid ground
Remove the jumpers at “JP2/JP3” and “JP5/JP6.” In
addition, verify that the input filter option is not
installed.
