Over/Under Voltage DC bus voltage is monitored for safe operation.
• For 200-240VAC input drives, the overvoltage trip occurs at a bus voltage of 400VDC
(equivalent to a 290VAC incoming line voltage).
• For 380-460VAC input drives, the overvoltage trip occurs at a bus voltage of 800VDC
(equivalent to a 575VAC incoming line voltage).
• For 200-240VAC input drives, the undervoltage trip occurs at a bus voltage of
210VDC (equivalent to a 150VAC incoming line voltage).
• For 380-460VAC input drives, the undervoltage trip occurs at a bus voltage of
390VDC (equivalent to a 275VAC incoming line voltage).
