NOTE:
If 0.22mm2 wire gauge is used for the Inhibit connections, the correct crimp is Tyco part 928990-1.
*If lower current limits are programmed for a particular ISM channel(s), it is possible to use smaller gauge wire. The
following recommendations are made.
NOTE:
Battery and motor wires should have 105ºC rated PVC insulation.
WARNING:
The chair manufacturer is responsible for establishing the suitability of the particular wiring arrangements used on the
wheelchair. Curtiss-Wright can make general recommendations for wiring for R-net control systems, but Curtiss-Wright
accepts no responsibility for, and accepts no liability for losses of any kind arising from, the actual wiring arrangement used.
6.3 BATTERY CONNECTIONS
The control system incorporates sophisticated current limiting circuitry as protection for the circuits in the control system.
ISO 7176-14 requires you to provide protection against short circuits in the battery wiring and the power loom or the extremely
unlikely event of a short circuit in the control system.
Place a suitable circuit breaker in series with the battery supply, for example in the link between two 12V batteries. If your
batteries are held in separate enclosures, you must provide a circuit breaker with each of them.
The rating of the circuit breaker must match the capacity of the wiring specified in section 6.2. The following table gives some
recommendations for circuit breaker selection. These recommendations are derived from well proven field experience of
various international wheelchair manufacturers. Nevertheless, manufacturers must confirm these recommendations by carrying
out suitable tests.
