1.8 Cabinet Clearances
The Galaxy 4000 UPS cabinet top clearance of 36 inches for fan exhaust is recommended. Additionally, adequate
space must be included in the front and top of each cabinet (approx. 36 inches) to allow the doors/panels of the
cabinet to be opened for service and maintenance procedures.
For an installation where seismic requirements must be met, additional clearance at the side of the cabinet must be
included to accommodate the seismic anchors. Contact your local MGE Sales Representative to order. See Figure 1-4.
1.9 Conduit Plate Locations for Bottom Entry
Cable entry through the bottom is the standard preferred design for the Galaxy 4000 UPS cabinet. The bottom entry
conduit plate provides space for up to five (5) separate conduit entries. The plate is secured with screws which
should be retained for the conduit plate after the power connections are made. See Figure 1-4 for the location of
the bottom entry conduit plates.
