Heat sinking
Chassis RG500 models require an additional heat sink
when the continuous armature current is above 7 ADC. Use
Minarik
®
part number 223-0235. All cased drives have
sufficient heat sinking in their basic configurations. Use a
thermally conductive heat sink compound (such as Dow
Corning
®
340 Heat Sink compound) between the drive chassis
and the heat sink surface for optimum heat transfer.
AC line and motor connections
Use 14 AWG or 16 AWG standard wire for connecting the
line and the armature. Use 16 AWG or 18 AWG standard wire
when connecting the field of a shunt wound motor. Strip the
wire insulation 0.25 inches (6 mm). See Figures 4 and 5
(page 10) for AC line and motor connections to chassis and
cased drives.
