Mounting the battery backup unit (BBU) can be done using one of two methods. The BBU can be mounted directly on top of the motor unit or it can be secured on a structural support just above it.
To prevent possible SERIOUS INJURY or DEATH from electrocution, disconnect power to motor unit BEFORE proceeding.

•Position the BBU on top of the motor unit. Make sure the motor unit power cord is drawn out from beneath the BBU. The BBU should sit firmly on top of the motor unit. Adjust angle iron placement so that it is out of the way of the BBU’s installation (Figure 1).
•Align the two screw slots on the BBU to the back chassis holes.
•Secure the BBU to each side of the chassis flanges with 3/4" screws provided.

•After the motor unit has been installed, position the BBU above the motor unit to a structural support (joist) within BBU’s cord length of 3' (.9 m) (Figure 2).
•Attach the BBU to the support by using the ceiling mount holes on either side of the BBU.
•Secure the BBU to the ceiling using
•Disconnect the motor unit from the electrical outlet.
•Connect the BBU cord into the connector on the right side of the end panel on the motor unit. Connect the motor unit into the electrical outlet. The BBU will activate and all LEDs will turn on for 3 seconds.
•The green LED will begin flashing indicating the BBU is charging from the motor unit.
IMPORTANT NOTE: Installation of BBU when permanent electrical power is not available (such as new construction and the electricity is not installed) may damage the batteries. Unplug BBU after testing to prevent damage.
