WARNING!
Models MMRG30U, MMRG30U-PCM, MMRG40U, and MMRG40U-PCM
require an additional heat sink when the continuous armature current
is above 5 amps. Use Minarik Drives heat sink kit part number 223-
0159. All other chassis drives have sufficient heat sinking in their basic
configuration. Use a thermally conductive heat sink compound (such as
Dow Corning® 340 Heat Sink Compound) between the chassis and the
heat sink surface for optimum heat transfer.
