3.2 Connections and Wiring
SHARK Power Module connections are located along the front panel of the
case.
3.2.1 General Wiring Notes and Recommendations.
The following notes apply to all wiring on the powerchair. Notes specific to
particular component wiring can be found under each component’s
designated sub-section (i.e. battery connections). It is the installer’s
responsibility to ensure the finished wiring package is safe and fit for purpose.
1. Before making any connections to the controller, disable the
powerchair by one of the following means to prevent accidental
movement.
•
Place the battery charger circuit breaker in the open position.
•
Disconnect the motor or batteries and/or elevate the drive
wheels.
2. All wiring should be as short as possible to prevent voltage loss at high
current.
3. The type of cable used must be appropriate for the mechanical and
environmental abuse it is likely to encounter.
4. Heavy gauge wire is mandatory for high current connections (batteries
and motors). For lower current wiring a gauge heavier than required to
meet the current carrying requirements is recommended for
mechanical robustness. Generally speaking wire gauges smaller than
0.5 mm

are not recommended because they are not sufficiently robust
for this application. Further details can be found in the sections
detailing component specific wiring requirements.
5. Wiring should be suitably restrained to prevent snagging and securely
fastened to the powerchair frame to ensure there is no strain on the
connectors.
6. Take particular care of the routing and securing of wiring on chairs with
moving or movable structures, such as seat raise, tilt, recline etc. Such
moving structures have the potential to crush and shear wiring, causing
potential safety issues.
