Static electricity caused by factors such as friction may lead to electrostatic discharge
(high voltage with low current) upon contact with the wheelchair; however, this does not represent
a health hazard. Since this may impair comfort, it can be prevented by mounting a ground strap
on the drive unit sustainer / wheelchair frame.
