	\|Voltage at which the DC contactor is allowed to close. It appears that the pre-charge relay output goes low when power is applied to the Inverter. This setting causes the HV relay to go to ground once the udc voltage climbs to the set value. If the udc voltage doesn't reach this value after 5 seconds, the inverter stops both relays by default and generates the Pre-Charge Fault. Setting this to 0 disables the pre-charge fault and skips the pre-charge state. Only set to 0 when manually doing pre-charge or when there is no high voltage connected inorder to test the outputs.		\|Voltage at which the DC contactor is allowed to close. It appears that the pre-charge relay output goes low when power is applied to the Inverter. This setting causes the HV relay to go to ground once the inverter is started (in manual mode or via the start input) and the udc voltage climbs to the set value. If the udc voltage doesn't reach this value after 5 seconds, the inverter stops both relays by default and generates the Pre-Charge Fault. Setting this to 0 disables the pre-charge fault and skips the pre-charge state. Only set to 0 when manually doing pre-charge or when there is no high voltage connected inorder to test the outputs.
