Mounting the Drive
You can mount your drive on the wide or the narrow side of the chassis. If you
mount the drive on the wide side, use #4 screws through the four corner holes. For
narrow side mounting applications, you can use #4 screws in the two side holes.
The amplifiers in the drive generate heat. Unless you are running at 1 amp or below,
you may need a heat sink. To operate the drive continuously at maximum power
you must properly mount it on a heat sinking surface with a thermal constant of
no more than 4°C/Watt. Often, the metal enclosure of your system will make an
effective heat sink.
Never use your drive in a space where there is no air flow or where other devices
cause the surrounding air to be more than 70 °C. Never put the drive where it can
get wet or where metal particles can get on it.

Unless you are running at 1 Amp/phase motor current or below,
you may need a heat sink. Often, the metal subpanel being
used for the control system will make an effective heat sink.
