NSTALLATION

Dynamic Electronic Controllers have been tested on typical vehicles to confirn

compliance with the following appropriate EMC standards:

Emissions:

Susceptibility:

ESD:

Compliance levels and set-up as per ISO 7176, part 21.

National and international directives require confirmation of compliance on

particular vehicles. Since EMC is dependant on the particular installation, each

variation must be tested. The guidelines in this section are written to assist with

meeting EMC requirements.

Minimising Emissions

Motors :

Motor brushes generate electromagnetic emissions. It may be

necessary to fit capacitors between the brush holders and the motor

case. Ensure the leads are kept as short as possible.

A suitable capacitor is 4n7, 250V Ceramic.

Wiring :

Keep wire lengths as short as practical for a tidy layout.

Minimise any wire loops, particularly loops of single wires as opposed

to wire pairs.

Endeavour to run wires in pairs or bunches.

Where practical, attach cables to the wheelchair frame.

Immunity to Radiated Fields

Follow the wiring recommendations for minimising emissions.

Immunity to ESD

Follow the wiring recommendations for minimising emissions.

Ensure all vehicle sub-frames are electrically connected.

Ensure any metal casing on speed setting potentiometers is electrically

connected to the vehicle frame.

Do not leave connections unnecessarily exposed.
