INSTALLING THE MMC SMART DRIVE
3.8 Controlling Heat Within the System
The MMC Smart Drive hardware case is designed to promote air circulation and
dissipate heat. Normally no fans or air conditioners are needed. However, if the
environment outside the control cabinet is hot or humid, you may need to use a fan,
heat exchanger, dehumidifier or air conditioner to provide the correct operating
environment.
Make sure that the temperature and humidity within the drive cabinet does not exceed
that which is shown in the specifications sections of this manual.
Make sure that components installed in the cabinet with the MMC Smart Drive do not
raise the temperature above system limits and that any hot spots do not exceed
specifications. For example, when heat-generating components such as transformers,
other drives or motor controls are installed, separate them from the drive by doing one
of the following:
• Place them near the top of the control cabinet so their heat output rises away from
the MMC Smart Drive.
• Put them in another control cabinet above or to one side of the cabinet with the
MMC Smart Drive. This protects the MMC Smart Drive from both heat and electri-
cal noise.
