Electromagnetic Compatibility (EMC)
Dynamic Electronic Controllers have been tested on typical vehicles to confirm
compliance with the following appropriate EMC standards:
USA:
ANSI/RESNA WC/Vol:2 - 1998 Sec 21
Europe:
EN12184:1999
Sec
9.8.1-3
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.
Minimizing Emissions
Motors:
•
Ensure the leads are kept as short as possible.
Wiring:
•
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.
•
Endeavour to run wires in pairs or bunches.
•
Where practical, secure the cables to the wheelchair frame.
Immunity to Radiated Fields
•
Follow the wiring recommendations for minimizing emissions.
Immunity to ESD
•
Follow the wiring recommendations for minimizing emissions.
•
Ensure all vehicle sub-frames are electrically connected.
•
Do not leave connections unnecessarily exposed.
