102 DC1 Variable Frequency Drive 04/16 MN04020003Z-EN www.eaton.com
An external radio interference suppression filter should be installed in the
immediate proximity of the variable frequency drive. In order to have an IP66
degree of protection, DX-EMC… radio interference suppression filters must
be installed inside an enclosure (IP66). In this case, the connection to the
variable frequency drive will require a screened cable with a screen braid that
is terminated at both ends to the protective earth (PES) across a large area.
Reference value potentiometer (0 - f
max
)
Operating direction selector switch
(FWD = Clockwise rotating field, REV = Counterclockwise rotating field)
Mains switch (PWR = Power)
External brake resistors can be connected to devices with a frame size of
FS2 or bigger.
￫
DC1-1D variable frequency drives do not have an internal radio
interference suppression filter.
An external radio interference suppression filter is required for
operation as per EN 61800-3, Section 6.8, “Radio
interference suppression filter“, page 153.
