Install the Shunt Resistor
Install your 2097-R x 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.
Mount Shunt Resistor to Heat Sink
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.
TIP Mounting holes are not equally spaced. Carefully lay out hole pattern before drilling holes in the
mounting surface.
