Note: To provide for adequate ventilation, a minimum of 36 inches clearance should be maintained above the top of the MGE Galaxy 4000 cabinet.

Cabinet Clearances

The MGE 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 the Customer Support Center to order.

Preparation for Storage

If the equipment is to be stored prior to installation, it should be stored in a cool, dry, well-ventilated location that is protected against rain, splashing water, chemical agents, etc. The equipment should be covered with a tarpaulin or plastic wrapper to protect it against dust, dirt, paint, or other foreign materials. See the section of this manual titled "Environmental Recommendations" for recommended storage environmental conditions.

Note: Batteries should be stored no longer than three (3) months at 25°C (77°F) or lower prior to recharging. Exceeding the recommended ambient storage temperature will reduce battery back-up time and may adversely affect battery life.
