7 Electrical system

7.1 Electronics protection system

The vehicle drive electronics is fitted with an overload protection.
If the drive is severely overloaded over a long period (for example,
during steep climbs) and, above all, at simultaneous high external
temperatures, the electronic system can overheat. In this case,
the vehicle performance is gradually reduced until it comes to a
standstill. The status display shows a corresponding flash code (please
refer to the user manual for your remote). If you switch the drive
electronics off and then on again, the error message is deleted and
the electronics can be switched on again. It can however take up to
five minutes until the electronics has cooled down enough for the
drives to apply their full performance.
If the drive is blocked due to an insurmountable obstacle, for
example, a curb or similar which is too high, and the driver attempts
to run the drive for more than 20 seconds against this obstacle, the
electronic system switches the drives off to avoid damage. The status
display shows a corresponding flash code (please refer to the user
manual for your remote). If you switch the drive electronics off and
then on again, the error message is deleted and the electronics can
be switched on again.
A defective main fuse may be replaced only after checking
the entire electric system. An specialized Invacare dealer
must perform the replacement. You can find information on
the fuse type in 11 Technical data, page 62.

7.1.1 The main circuit breakers

The circuit breakers (1) are located on the left sides of the battery
boxes as shown above. If the electrical system draws too much
power for a period of time, one or both may overheat and pop out.
1. To reactivate the electrical system, wait a few minutes until they
have cooled down a bit, then push them back in.

7.2 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.

7.2.1 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.
