Cabinet Placement and Environment

The complete STS system may consist of more than one cabinet depending on whether the STS is a stand-alone
unit or it is used in conjunction with input isolation or output distribution cabinets such as the Power Management
Module 2 (PMM 2 ) cabinets. Cabinets must be arranged in the required positions to ensure proper connections.
When facing the Epsilon STS™ from the front, the standard arrangement provides for any PMM
cabinets to be located on the right hand side. The PMM
interconnect cables and side barrier(s) are supplied with the PMM
supplied with the Epsilon STS™.
The Epsilon STS™ is intended for use in an environment where control of temperature and humidity is provided.
The maximum operating and recommended environmental parameters are listed in Appendix B.
The Epsilon STS™ cabinets generate heat and exhaust air through the top portion of its enclosures. Air intake is
through the lower front or bottom of the cabinet. All other auxiliary cabinets are convection cooled. To assist you
in planning for your HVAC needs, heat rejection data is provided in Table 2.1 for a worst case scenario (i.e.,
maximum rated power output).

Clearances and FootPrint

As can be seen in the following illustration, the footprint for each cabinet is nominally 30" deep. Additionally,
adequate space must be included in the front of each cabinet (approx. 36") to allow the door of the cabinet to be
opened for service and maintenance procedures.
