Connecting the Battery Adapter to a Wheelchair
Definition
The Battery Adapter connects to the +24VDC power source of a wheelchair. Power
drawn by the Battery Adapter is converted to two voltages, +12VDC and +9VDC.
Procedure
Complete the following steps to connect the Battery Adapter to a wheelchair power
source:
1. Connect the Battery Adapter Input Power Cable (P/N: 9252) shown as (A)
to the connector on the Battery Adapter labeled “+24V Input”.
2. Connect the ring terminals shown below as (B) to the wheelchair batteries.
Caution
Be sure to observe polarity as marked on the cable! The ring lugs are marked
+24V and Ground. The +24V ring lug should be connected to the positive
connection of the wheelchair batteries while the ring lug labeled Ground should be
connected to the negative connection of the wheelchair battery.

(cont.)
Procedure (cont.)
3. Dress the wires from the wheelchair battery neatly so they don’t get caught
on anything.
4. After everything is connected, it should look like the figure below where (A)
is the +12VDC output, (B) is the +9VDC output, (C) is the negative battery
connection, and (D) is the positive battery connection.
Caution
Use extreme caution when working with any battery. Wheelchair batteries in
particular are designed to provide large amounts of power.
Shorting the wheelchair battery terminals could result in severe burns!
Contact your local Quartet distributor to install the Battery Adapter.

Safety Features
Introduction
The Battery Adapter contains two internal non-replaceable fuses to protect from:
• Reverse input protection
• Over voltage input
• Catastrophic failure
• Shorted Outputs
• Battery Adapter Input Power Cable Fuse
Reverse Input Protection
The Battery Adapter features a reverse input protection circuit in the event the input
from the Battery Adapter Input Power Cable is connected improperly.
Over Voltage Input
The Battery Adapter has been designed to withstand transient voltages up +60VDC
that last up to a millisecond in length.
Catastrophic Failure
In the event the Battery Adapter fails, the internal fuse will “blow” to protect the
Battery Adapter. If this happens, the unit will have to be returned for repair.
Shorted Outputs
In the event the +12VDC and/or the +9VDC outputs becomes shorted, the Battery
Adapter will automatically trip an internal fuse and shut the outputs down.
If this happens, you must remove the +24VDC input by disconnecting the Battery
Adapter Input Power Cable for at least 1 minute. Be sure to remove the “short”
before reattaching the Battery Adapter Input Power Cable.
Battery Adapter Input Power Cable Fuse
The Battery Adapter Input Power Cable includes a built-in replaceable fuse shown
as (A) below:
Use only a Littlefuse 2A Mini Fuse type if replacement is needed.
