The Allen-Bradley 1394-SR10A external shunt resistor kit is a spare part for the Allen-Bradley 1394 digital AC motion control system with multiple axes. The 1394-SR10A external shunt resistor kit is intended for 5-kilowatt and 10-kilowatt rated Allen-Bradley systems that have regenerative loads that exceed the capacity of the systems' internal shunt resistors that are rated at 200 Watts. Not all Allen-Bradley systems that are rated at 5 kilowatts and 10 kilowatts need an external shunt resistor kit, but the ones that regularly handle large regenerative loads do, and so do Allen-Bradley 22-kilowatts rated 1394 and 8520 systems because they do not come with built-in shunt resistors. The external shunt resistor kit like the 1394-SR10A external shunt resistor kit will dissipate the excessive energy that would overload a system's internal resistor and possibly damage the internal resistor or the whole system.

Always install the Allen-Bradley 1394-SR10A external shunt resistor kit according to all the local safety codes. Guard the resistor properly so that machine operators will not accidentally touch it and do not install anything flammable near it because it can reach a temperature of 662 degrees Fahrenheit or higher. This resistor can be mounted with 2 M10 3/8-inch bolts in a vertical position on a metal surface that will not experience vibrations or shocks and that will not collect dust, corrosive vapor. moisture, and oil or oil mist. The 1394-SR10A external shunt resistor kit uses a fuse that needs to be replaced after it has been activated and used. Always ensure that the power is disconnected from the external resistor before replacing the fuse, and note that the resistor may have more than 1 power source.
