Dynamic Electronic Controllers have been tested on typical vehicles to confirm
compliance with the following appropriate EMC standards:
USA:
Europe:
National and international directives require confirmation of compliance on
particular vehicles. Since EMC is dependant on a particular installation, each
variation must be tested. The guidelines in this section are written to assist with
meeting EMC requirements.

Motor brushes generate electromagnetic emissions. It may be
necessary to fit capacitors between the brush holders and motor case.
Ensure the leads are kept as short as possible.
A suitable capacitor is 4n7, 250V Polypropylene.
Keep wire lengths as short as practical for a tidy layout.
Minimize any wire loops, particularly loops of single wires as opposed
to wire pairs.
Endeavor to run wires in pairs or bunches.
Where practical, tie cables to wheelchair frame.
Follow the wiring recommendations for minimizing emissions.
Follow the wiring recommendations for minimizing emissions.
Ensure all vehicle sub-frames are electrically connected.
Do not leave connections unnecessarily exposed.
