FVR-C9S-7UX
CAUTION:
The control circuit terminal wiring should be
kept as far as possible from the main circuit
wiring to prevent operational error due to
noise interference. Never install them in the
same duct or conduit. (A separation distance
of 4 inches [10cm] or more is recom-
mended.) If the control circuit wiring must
cross the main circuit wiring, make sure it
crosses at a right angle.
Use shielded, twisted wire for the control
circuit wiring , which should be as short as
possible (65 feet [20m] or less).
Install a surge absorber in parallel with any
magnet contactors, solenoids, relays or
timer coils, which are close to the drive.

* The use of quick-acting fuses is required to validate UL listing. The factory C92-7-15
recommendation is Bussman type JKS or equivalent.
Long wiring lengths between the motor and
the drive will result in increased capacitance
and leakage current. This may cause earlier
activation of such protective functions as:
overcurrent protection, overheating protec-
tion and electronic thermal overload, or the
error in current detection may become large.
To avoid these, adjust the length of wiring
between the drive and the motor so that is
does not exceed the length shown below.
