Charging Batteries
Ꮨ DANGER
When using an extension cord, use only a three wire extension cord having at least
16 AWG (American Wire Gauge) wire and the same or higher electrical rating as
the devise being connected. Use of improper extension cord could result in a risk of
fire and electric shock. Three prong to two prong adapters should not be used. Use
of three prong adapters can result in improper grounding and present a shock
hazard to the user.
NEVER attempt to recharge the batteries by attaching cables directly to the battery terminals.
DO NOT attempt to recharge the batteries and operate the wheelchair at the same time.
DO NOT operate wheelchair with extension cord attached to the AC cable.
DO NOT attempt to recharge the batteries when the wheelchair has been exposed to ANY
type of moisture.
DO NOT attempt to recharge the batteries when the wheelchair is outside.
DO NOT sit in the wheelchair while charging the batteries.
DO NOT attempt to recharge batteries using BOTH the on‐board battery charger and an
independent battery charger (plugged into the joystick charger port) at the SAME time.
Doing so will reduce the life of the batteries.
READ and CAREFULLY follow the manufacturer’s instructions for each charger
(supplied or purchased). If charging instructions are not supplied, consult a qualified
technician for proper procedures.
AFTER charging batteries, ALWAYS make sure that the battery charger cord is securely
wrapped and stored within the hook and loop strap assembly on the rear of the battery
tray. Failure to do so may result in damage to the cord or personal injury to the user or
bystanders.
Ensure the pins of the extension cord plug are the same number, size, and shape as those
on the charger.
DO NOT under any circumstances cut or remove the round grounding plug from the
charger AC cable plug or the extension cord plug.
Grounding Instructions
DO NOT, under any circumstances, cut or remove the round grounding prong from any
plug used with or for Invacare products. Some devices are equipped with three‐prong
(grounding) plugs for protection against possible shock hazards and fire. Where a two‐
prong wall receptacle is encountered, it is the personal responsibility and obligation of the
customer to contact a qualified electrician and have the two‐prong receptacle replaced with
a properly grounded three‐prong wall receptacle in accordance with the National Electrical
Code. If you must use an extension cord, use ONLY a three‐wire extension cord having the
same or higher electrical rating as the device being connected. In addition, Invacare has
placed RED/ORANGE warning tags on some equipment. DO NOT remove these tags.
