1.5 Preparation for Operation
Several items must be considered when preparing the Galaxy 4000 UPS system for operation.
First The UPS cabinet and its auxiliary cabinets must be arranged in the required configuration to insure that
the interconnection cables are located in the correct adjacent cabinets.
Second The cabinets must be in a location that provides for proper air flow and heat rejection.
Third The room in which the Galaxy 4000 UPS system is located must maintain environmental conditions within
recommended tolerances.
Forth All electrical connections must utilize the top or bottom conduit entries provided.
The following sections discuss these items in more detail.
1.6 Cabinet Placement
The complete UPS system may consist of one to three cabinets depending on the options selected. The UPS
cabinet allows system options to be selected based on the application. When facing the Galaxy 4000 UPS from the
front, the standard arrangement provides for any external batteries to be located on the right hand side, and the
distribution cabinet to be located on the left hand side of the UPS. Refer to Figure 1-3 for cabinet placement.
1.7 Heat Rejection and Air Flow
The Galaxy 4000 UPS cabinets generate heat and exhaust air through the top portion of its enclosures. Air intake
is through the bottom and front of the cabinet. All other cabinets are convection cooled. To assist you in planning for
your HVAC needs, heat rejection data is provided in Table 1-1. The cabinet airflow and recommended top clearance
are provided in Figure 1-3. The Galaxy 4000 is intended for use in an environment where control of temperature
and humidity is provided.
