Mounting and wiring instructions
4.1
Heat Sink Mounting
The VIO series dissipates its heat by natural convection for loads up to 500W. For higher output loads the
amplifier should be mounted on an additional heat sink or cooled by fan. Care should be taken that the
motor leads are as short as possible. The capacitance of long shielded motor leads can cause the amplifier
to generate a significant amount of heat. There are two 4.5mm holes in the base plate for mounting to an
additional heat sink (see Figure 5).
