Resistor

A 1 kOhm precharge resistor is required across the contacts of the contactor.  The precharge resistor allows the capacitors of the controller to charge prior to the contactor closing, preventing arcing and damage to the contacts.  The precharge resistor was included in the motor/controller/contactor package, wired with ring terminals for easy installation on the contactor.
