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

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.
