1.1.4 Cabinet Descriptions and Placement
The complete UPS system may consist of one to four cabinets depending on the options selected.
The UPS will be
housed in either a "Standard" or "Micro" cabinet. The Micro cabinet is offered for applications where space is at a
premium, while the Standard cabinet is offered for either larger kVA requirements or for applications with input trans-
former requirements. For the Micro cabinet to achieve the maximum space savings, the configuration must be
offered with a minimum number of options. The Micro cabinet based Galaxy 3000 is available where the
input/output voltage is 208/208 VAC and options such as an external maintenance bypass, output distribution, input
isolation or extended batteries are either not required or are accomplished with existing auxiliaries or third party
solutions. The Standard Cabinet allows all such system options to be selected based on the application. When
facing the Galaxy 3000 UPS from the front, the standard arrangement provides for any external batteries to be
located on the right hand side, and all other auxiliary cabinets to be located on the left hand side of the UPS.
1.1.5 Cabinet Clearance and Environmental Requirements
1.1.5.1 Air Flow / Heat Rejection
The Galaxy 3000 UPS cabinets generate heat and exhaust air through the top portion of its enclosures. Air intake
is through the bottom 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, (i.e., 480 VAC input / 480 VAC output).
1.1.5.2 Recommended Operating Environments
The Galaxy 3000 is intended for use in an environment where control of temperature and humidity is provided. The
Cabinet airflow and recommended top clearance are provided
in Figure 1-2.
Table 1-1: Heat Rejection Data.
Heat Rejection Data @ 480/480 VAC
UPS Module BTU/Hr
10 kVA 6,824
15 kVA 10,235
20 kVA 12,965
30 kVA 19,447
See section 2.1 Electrical Specifications for specific Heat Rejection data based on kVA sizing and voltage require-
ments.
NOTE
To provide for adequate ventilation, a minimum of 36in (914.4)
clearance should be maintained above the top of the Galaxy
3000 cabinet.
