Installing the Auxiliary Power Unit
The Control Unit Diagram on the back of Form 1, System Planning, indicates
whether an auxiliary power unit is required for the carrier that you are installing.

Use the 9024 auxiliary power unit for new installations. You can continue
to use a previously installed 335A auxiliary power unit, as long as no new
telephones or modules are added to the carrier.
To install an auxiliary power unit, follow the steps below. Refer to
throughout this procedure.
Turn off the switch on the power supply.

Mount the auxiliary power unit on a surface (preferably the

backboard) within 2 ft. (61 cm) of the control unit.

the power supply.
Plug the other end of the line cord into the AUX POWER jack on the

auxiliary power unit.
