Active shunts are available from the Rockwell Automation Encompass™ partner
Powerohm Resistors, Inc. (http://www.powerohm.com).
IMPORTANT Powerohm Bulletin PKBxxx active shunt modules use built-in internal brake
For compatible Powerohm active shunts paired with 2198-Pxxx DC-bus
power supplies and 2198-RPxxx regenerative bus supplies, see

(1) The active shunt (RC) connector is rated for wire size up to 6 mm
connect to the shunt, the drive connection must be made to the external DC-bus connections on an accessory module.
(2) Configure any available digital input as Shunt Thermal Switch OK. See the
(3) Powerohm PKB050 and PKB050-800 shunts require 120V AC between pins 9 and 10 to supply power to the cooling fans.

ATTENTION: To avoid damage to the Kinetix 5700 drive system, wire the
active shunt thermal switch to a digital input on the power supply and
configure the Shunt Thermal Switch OK function in the Logix Designer
application.
