Install the Shunt Resistor
Install your 2097-Rx shunt resistor by using the dimension drawing on page 4 and two
M4 (#6-32) steel machine screws. Torque to 1.1 N•m (9.8 lb•in).
The shunt resistor can operate at its full power rating if it is mounted vertically on a
200 x 200 x 3 mm (7.9 x 7.9 x 0.12 in.) heat sink at 25 ºC (77 ºF) with a clearances of 12 mm
(0.5 in.) on the sides and 50 mm (2.0 in.) above and below. If you’re not using a heat sink, refer to
the derating information in the user manual.
ATTENTION: The shunt resistor surface temperature can reach up to 200 ºC (392 ºF). Do not
touch during operation. Do not install near flammable material. We recommend that you
install in a manner that prevents user contact.
Mount Shunt Resistor to Heat Sink
Mounting holes are not equally spaced. Carefully lay out hole pattern before drilling holes in the
mounting surface.

Wire the Shunt Resistor
The shunt resistor is wired into connector BC, a 7-pin quick-connect terminal block, which is
plugged into the Shunt/DC Bus terminal on the front of the drive. The shunt resistor connects
between the Positive DC Bus (either BC-1 or 2) and BC-4.
