Chapter 1 Installation
Location (Environment) NOTICE: Install this equipment in an indoor temperature-controlled area, free from
condensation and conductive contaminants such as carbon dust.
The MiniDySC must be installed in a protected environment. The location must
provide adequate airflow around the MiniDySC in an atmosphere free from
excessive dust, corrosive fumes, or conductive contaminants. Do not operate the
MiniDySC in an environment where the ambient temperature or humidity is
beyond the specified limits given in this manual.
Mounting Considerations The MiniDySC can be wall mounted. It can also be mounted inside an enclosure
as long as the ambient temperature remains at or below 40°C.
Note: The input and output wiring is from the bottom of the MiniDySC and considerations
should be made to accommodate the additional space. The weights for the MiniDySC are given
on
page 18 .
Rack Mount Considerations Special instructions for installing the rack-mount MiniDySC are in Appendix A .
Heat Dissipation The table below provides full-load power dissipation for the three MiniDySC
sizes. Refer to this chart when calculating heat dissipation for placing the
MiniDySC in your cabinet.
