Default Re: Precharge necessary?

From Ian:

The Alltrax controllers do require an external precharging system. On all their example wiring diagrams they just show a resistor permanently across the main contactor, which works OK but isn’t quite as safe as a staged precharger. I’d probably recommend getting the EVMS with built-in precharger and using that if you can (would involve slightly different wiring).
