WARNING: Serious Personal Injury
• Securely mount the enclosure to the ground to prevent tipping. Failure to do so could
lead to serious injury or death.
• Wear appropriate protective equipment when working with batteries, including eye or
face protection, acid-resistant gloves, an apron, and any other necessary items.
• Keep plenty of fresh water and soap nearby in case battery acid contacts skin or clothing.
• If acid enters the eye, immediately rinse the eye with running cold water for at least 20
minutes and seek medical attention immediately.
CAUTION: Personal Injury
• Wear gloves while assembling or moving the empty enclosure. Sheet metal edges are
sharp and may lacerate unprotected skin.
• Use eye and ear protection when drilling.
• Always use proper lifting techniques. The empty enclosure or individual batteries are heavy.
• Use assistance to move the assembled empty enclosure into place.
CAUTION: Equipment Damage
• Follow all installation instructions in this document. Failure to complete the installation
per these instructions may lead to product damage or risk of personal injury.
• Follow all manufacturer’s instructions for battery installation. Overtightening or
incorrectly connecting batteries can irreparably damage the batteries.
• Equipment connections must be in accordance with the National Electrical Code (NFPA
70), current edition. If installed in Canada, all wiring methods shall be in accordance
with the Canadian Electrical Code, C22.1, current edition.
NOTE: Additional Equipment Information
• This document covers information for OBE-3-FT installation and use. Refer to the
specic equipment documentation for other OutBack products used in conjunction
with this equipment. For more information go to www.outbackpower.com.
WARNING: Explosion, Electrocution, or Fire Hazard
• Never smoke, or allow a spark or ame near the batteries.
• Ensure space between each battery is ½" (1.3 cm) minimum for convection cooling.
• Keep the area around the enclosure well ventilated and free of debris.

Precast Pad Installation
Outback recommends using precast polymer mounting pads. These pads are designed for proper cabinet
support and ease of installation. Drilling areas for openings are indicated for coaxial and service sweeps, and
pre-installed threaded inserts for enclosure attachment.
Site Considerations
• The site must be planned so the enclosure receives good air ow. In areas of extreme heat, position the
enclosure so that it will be shaded from the afternoon sun. In areas of prevailing winds, it is best that the
enclosure be located so that the sides of the cabinet face the winds instead of the doors. This will greatly
reduce the buildup of sand or snow against the enclosure’s air vents.
• In areas of potential ooding, the site must be located above the 100-year ood plain.
• The enclosure must be placed where it will be free of obstructions, allowing easy access to the doors for
service or equipment access. For ventilation and maintenance near other solid structures, allow a minimum
space of 36" (91 cm) between the front and rear of the enclosure, as well as on the sides.
• Place the enclosure well away from sources of forced water, such as underground sprinkler systems and direct
roadway splash.
• The concrete pad drawing provided in this manual contains all of the required mounting details, including
electrical service and cable plant entrances.
• For ease of installation, lightweight polymer concrete pads are available from Outback for the OBE-3-FT
enclosure.
• The vapor barrier material (such as 30 lb. felt, neoprene pond liner, or heavy grade tar paper) must initially
extend at least 6" (15 cm) in all directions around the perimeter of the enclosure and then be trimmed closer
to the enclosure.
• Contact local utilities or cable/piping locator services to ensure that the installation does not interfere with
existing cables or piping.
