PurposeThis document provides instructions for the initial assembly and installation of the Indoor Battery Enclosure (IBE) Series.
ScopeThis document applies to all models of the IBE Series: the IBE-1 (1–48V battery string) and IBE-2 (2–48V battery strings). The IBE Series is designed to shelve the following OutBack EnergyCell RE Top Terminal Batteries: 78RE, 95RE, 106RE 12Vdc VRLA. Alternative top terminal batteries used with this enclosure should first be reviewed with the respective battery manufacturer for compatibility.
WARNING: Serious Personal Injury• Securely fasten the enclosure to the floor to prevent tipping when the battery trays are
used. 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 other 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• Do not pull out more than one battery tray at once, as the enclosure may tip.• 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.• Install the enclosure in an environmentally controlled location within sight or
co-located with the inverter. If installed in Canada, all wiring methods shall be in accordance with the Canadian Electrical Code, C22.1, Current Edition.
NOTICE: Additional Equipment Information• This document covers information for IBE-1 and IBE-2 installation and use. Refer to the
specific equipment documentation for other OutBack products used in conjunction with this equipment. For more information go to www.outbackpower.com.
• The IBE-1 and IBE-2 are designed to support inverter systems rated up to 4kW. Do NOT use this product in conjunction with greater than 4 kW inverter systems.
WARNING: Explosion, Electrocution, or Fire Hazard• Never smoke, or allow a spark or flame near, the batteries. • Ensure space between each battery is ½" (12.7 mm) minimum for convection cooling.• Keep the area around the enclosure well ventilated and free of debris. • Always use insulated tools. Never rest tools on top of batteries or other electrical parts.
Enclosure mounting procedure:1. Measure and mark the mounting
locations from the anchor holes on the bottom of the unit (see Fig. 1 and Fig. 2). Ensure that there are at least 4" between the wall and the nearest mounting hole.
2. Using a hammer drill and a ½" masonry bit, drill a hole 2 ½" deep.
3. Clean the hole using compressed air and/or a vacuum.
4. Place the enclosure so the mounting holes line up with the holes in the floor.
5. Remove the nut and small washer from the anchor assembly, and install the 3/8" x 1-1/4" OD washer to the assembly as shown in the inset in Figure 3.
6. Insert the anchors into the holes (make sure the nuts are just below the top of the stud).7. Finger tighten all of the nuts.8. Once snug, use a wrench to finish tightening the anchors (approximately 2-4 full turns, or 50-60 ft-lb). Be careful
not to over tighten.
Conduit connection:The IBE-1 and IBE-2 come supplied with a 1-1/2" reducing washer for connecting conduit to the enclosure.
1-1/2" conduit will support the use of electrical wire up to 2/0 in size. Proper wiring sizing is essential for safe and problem free operation of battery charging. Consult your OutBack distributor/installer or certified electrician for proper wire sizing.

Standard Installation Optional Assembly with Anti-tip Plate
Anti-tip plate mounting procedure:Use at least one other person for assistance with this procedure.1. Place the enclosure on its side.2. Place blocks under the enclosure to raise the enclosure at least 3" off the
ground, see Fig. 5. Ensure the enclosure is resting levelly .3. Align the mounting holes in the anti-tip plate with the mounting holes
on the bottom of the enclosure (orient the anti-tip plate handle to the front of the enclosure, as shown in Figure 6).
4. Insert the flat head screws through the bottom of the anti-tip plate.5. From inside the enclosure, attach the flat washer, lock washer, and nut to
each screw. Finger tighten all of the nuts.6. Use the ⁹⁄₁₆" socket wrench and screw driver to finish tightening the nuts.7. Stand the enclosure upright.
CAUTION: Personal Injury• The anti-tip plate is heavy. Use caution when attaching the anti-tip plate to the enclosure.• Wear gloves while assembling or moving the anti-tip plate. Sheet metal edges are sharp
and may lacerate unprotected skin.• Use proper lifting techniques.• Use at least one other person for assistance when installing the anti-tip plate.

CAUTION: Personal Injury• Always mount the IBE using either the sleeve anchors or the anti-tip plate. Failure to
properly mount the IBE may result in tipping and personal injury.
WARNING: Electrical Hazard• Under sizing wire in electrical applications increases the risk of short circuits and fire. Installa-
tions should always be performed by an OutBack Installer or a certified electrician.

Battery installation procedure:1. Unlatch and slide the battery tray out to the stops. DO NOT install or remove batteries in both trays
simultaneously, as this may result in the enclosure tipping, severe personal injury and equipment damage.2. Position the batteries as shown in Fig. 9 (for IBE-1) or Fig. 11 (for IBE-2).3. Wire the batteries in accordance with Fig. 10 (for IBE-1) or Fig. 12 (for IBE-2). 4. Make all battery terminal connections per Fig. 7 and 8 below (offset lugs so hardware seats properly). Torque
all the terminal connections to the manufacturer's specifications.5. Apply corrosion inhibitor to the terminals and connections.6. Unlatch and slide the tray evenly into the enclosure. The battery drawer slides may be damaged if the drawer
is forced into the enclosure while the slide latch is engaged.
