9.2 Electrical fuses, (Circuit Breakers):
To prevent the wheelchair from becoming overloaded,
an electronic safety system has been built in, which
automatically disconnects the battery from the control.
This device cuts in only in extreme circumstances, such
as repeated climbing of steep hills in very high ambient
temperatures. The fuse button, located on the side of the
battery, trips immediately and the wheelchair comes to a
stop. The fuse can be reset by pressing the button. After a
few seconds the wheelchair can be driven again normally,
(Fig.9.1).
Fuses:
1. 50 A Fuses are connected into the battery harnesses to
protect the batteries and wiring.
2. 30 A Circuit Breakers with reset buttons. These are
located on the front left side of the battery boxes.
To replace them contact your Sunrise Medical authorised
dealer, who will also diagnose the fault.
