Epilson STSTM

2.1Cabinet 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 Module2 (PMM2) 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 PMM2 Plus auxiliary cabinets to be located on the right hand side. The PMM2 Ultra has cabinets located on both sides of the STS. The interconnect cables and side barrier(s) are supplied with the PMM2 cabinet. The interconnect brackets are 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).

2.2Clearances 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.
