I have an AB Kinetix 350 that I'm setting up in a new system. I am getting a Overvoltage fault, as my DC buss is spiking to 850VDC. The book says to install a shunt resistor, 2097-R6, and to install it on a heat sink:
The shunt resistor can operate at its full power rating if it is mounted vertically on a 200x200x3mm(7.9x7.9x0.12in.) heatsink at 25C (77F) with a clearance of 12mm (0.5 in.) on the sides and 50 mm (2.0 in.) above and below.

What it does NOT say is what that heat sink should be made of. Am I supposed to just use a piece of aluminum stock cut to size drilled into the cabinet wall? Should I mount it with thermal paste? This thing says it will reach up to 392F. That's a lot of heat inside the cabinet. What's the best practice here?
