    These instructions are provided so that an OEM can officially convert a  W-VACiMB Mining Breaker to an approved secondary variation. This variation is required for some OEM’s for them to be in compliance with end customer needs. The OEM is authorized to do the conversion per this process and to still have the proper warranty protection.

    65A7320H01 Due to jumping connections in this procedure, the three relays will  have the same voltage/supply as the charge motor. Similarly, the UVR, Close Coil, Charging Motor, and Trip Coil will share a common return (See Appendix A). You may choose to not install the jumpers for more circuit flexibility.
