Q M- 7 10/7 15HD/ 72 0
A. INTRODUCTION
1. Notes–
•
Batteries supply the power for your chair. They contain a
finite amount of energy and have limits on how long they
can store and supply energy.
•
You can charge batteries only a certain number of times
before they will fail and no longer hold a charge.
•
For answers to questions about batteries, consult your
Authorized Dealer.
2. Use Proper Batteries:
Your chair operates on two 12 volt batteries.
•
They should be Group 24, 34 (or 22NF) size with a minimum
of 50 ampere hour rating.
•
Only deep cycle sealed case construction batteries should be
used in this device.
•
Connecting Type: Post style batteries or flat top batteries
(used when lowest seat-to-floor height is desired).
•
When you buy a replacement, insist on a deep cycle sealed
case type. Do not use any other kind of battery.
•
Group 24 batteries are a minimum requirement for power
seating.
3. Breaking In:
•
A battery requires "breaking-in" for the first 6 to 12
charges. It will not accept a full charge for this period.
•
It is best to limit the length of your trips until you break the
batteries in and you know the range of your chair.
4. Discharged Batteries:
Never allow a battery to completely discharge. If you oper-
•
ate your wheelchair until it has almost stopped, you will
greatly reduce the life of your batteries.
•
Never let a battery sit in a discharged condition. Give
unused or stored batteries a full charge once per month.
•
Always fully charge the batteries. Avoid charging when it is
not necessary.
Never connect a life support or auxiliary device to a wheelchair
battery. The electrical system may fail, and result in severe injury to
or death of user.
B. CHARGING YOUR BATTERIES
To avoid the risk of severe injury or death from electrical shock,
fire or explosion while charging: Never connect charger to a 240
volt source. The main input voltage is 110 volts. Never make
direct contact across both battery terminals, as an explosion may
occur. A spark may result in an explosion and/or fire resulting in
severe injury or death.
Never touch the charger after it is connected to an electrical out-
let. This may cause electrical shock.
Never connect or disconnect charger from battery while there is
power to the charger.
WARNING
WARNING
WARNING
1. Never use an extension cord. Use of an improper cord
could damage the charger or cause a fire or electrical shock.
2. A battery emits explosive hydrogen gas during charging. To
reduce the risk of fire or explosion:
•
Never smoke or allow a spark, flame or high heat near
battery during charging.
•
Never allow metal tools or chair parts to make direct
contact across both battery terminals.
ALWAYS:
1. Use the charger that comes with your wheelchair. Read and
follow all instructions and warnings.
2. Make sure room is well ventilated.
3. Turn off all power to your chair.
4. Connect and disconnect battery cables with caution.
NOTE– Always remove and reattach the negative cable (black cable) first.
5. Make sure to allow enough time to fully charge batteries.
NOTE– Batteries should never be left for long periods in the discharged
state. Unused or stored batteries should be given a
charge once per month.
Procedure for connecting the charger and charging
Connect the battery charger round output plug to the charging
•
socket on the front of the joystick module, Fig. 45
Connect the charger to the main supply by means of the main
•
plug and switch on wall socket if necessary.
The GREEN light will flash to show power is on and the
•
charger is initializing.
The ORANGE light comes on to show that the batteries are
•
charging.
Flickering between ORANGE and GREEN shows that charge is
•
almost complete.
Solid GREEN indicates charge is complete.
•
When buying replacement batteries or charger always consult your
Sunrise Medical service agent. Do not leave the charger connected
to the battery with the mains disconnected or switched off. This
could result in damage to your battery being caused by deep
discharge over a period of time.
To reduce the risk of damage to electric plug and cord, pull by the
plug rather than the cord when disconnecting the charger.
