6 Electrical system

6.1 Electronics protection system

The vehicle's electronics are fitted with an overload-protection
system.
If the motors are put under considerable strain for a longer period of
time (for example, when driving up a steep hill) and especially when
the ambient temperature is high, then the electronic system could
overheat. In this case the vehicle's power is reduced gradually until
it finally comes to a halt. The status display shows a corresponding
error code (refer to10.1.2 Error codes and diagnostic codes, page
37). By switching the power supply off and back on again, the error
code is cancelled and the electronics are switched back on. It will
take approximately five minutes until the electronics have cooled
down enough for the motors to restore full power again.
When the motors are stalled by an insurmountable obstacle, such as
a high curb, and the vehicle driver allows the motors to strain against
this hindrance for more than 20 seconds without moving, then the
electronics will automatically switch off to prevent the motors from
being damaged. The status display shows a corresponding error
code (refer to10.1.2 Error codes and diagnostic codes, page 37). By
switching off and back on again, the error code is cancelled and the
electronics are switched back on.

6.1.1 The main fuse

The entire electric system is protected against overload by two
master fuses. The master fuses are mounted on the positive battery
cables.

NOTE
– A defective main fuse may be replaced only after
checking the entire electric system. An Invacare
specialised dealer must perform the replacement. You
can find information on the fuse type in chapter 11
Technical data, page 40.

6.2 Batteries

Power is supplied by two 12 V batteries. The batteries are
maintenance-free and only need regular charging.
In the following, you find information on how to charge, handle,
transport, store, maintain, and use batteries.

6.2.1 General information on charging

New batteries should always be fully charged once before their first
use. New batteries will be at their full capacity after having run
through approx. 10 - 20 charging cycles (break-in period). This
break-in period is necessary to fully activate the battery for maximum
performance and longevity. Thus, range and running time of your
mobility device could initially increase with use.
Gel/AGM lead acid batteries do not have a memory effect as NiCd
batteries.

6.2.2 General instructions on charging

Follow the instructions listed below to ensure safe use and longevity
of the batteries:
•
Charge 18 hours prior to initial usage.
•
We recommend charging the batteries daily after every
discharge even after partly discharge, as well as each night over
night. Depending on the level of discharge, it can take up to 12
hours until the batteries are fully charged again.
