DANGER!
• As with all main powered electrical equipment, always
replace blown fuses with the same type and size of fuse as
specified.
• Fitting of different fuses can result in an increased fire risk,
damage to the charger
,
or failure of the charger to operate
properly.
6.3 The range of your vehicle
Most manufacturers of mobility products state the range of
their vehicles either in the sales literature or within the
User Manual. The range stated sometimes differs from
manufacturer to manufacturer
,
even though the battery
size is the same. Sunrise Medical measure
s
the range of
their vehicles in a consistent and uniform manner, but
variances still occur due to motor efficiencies and overall
product load weight.
The range figures are calculated to ISO 7176-4:2008, Part 4:
Wheelchair Energy Consumption Theoretical Range
.
This test is carried out in controlled conditions with new,
fully charged batteries, on a level test surface and a user
weight of 220 lbs (100 kg). The range figures stated should
be seen as a theoretical maximum and could be reduced if
any single, or combination, of the following circumstances
occur:
• User weight heavier than 220 lbs (100 kg).
• Batteries whose age and condition are less than perfect.
• The terrain is difficult e.g. very hilly, sloping, muddy ground,
gravel, grass, snow
,
and ice.
• The vehicle climbs curbs regularly.
• The ambient temperature is very hot or very cold.
• Incorrect tire pressures in one or more tires.
• Lots of start/stop driving.
• Also thick pile carpets within the home can affect range.
• Use of additional power consumption options (e.g. light,
actuators, etc.)
The battery sizes available on each Sunrise Medical
product should give sufficient range to cope with the
majority of customer’s lifestyles.
B
att
ery Charger
The external charger has been designed to charge two 12V
Gel type batteries connected in series (= 24 V).
The chargers have features which prevent hazards or
accidents occurring as a result of connecting
batteries
the
wrong way round, overheating caused by fault conditions
,
or
attempting to charge wrong voltage batteries.
The majority of charger sizes are electrically double
insulated and no earth connection is required. Some larger
sizes may be electrically earthed and this will be clearly
stated on the label.
