160-NX3 Series C Drive These instructions are intended to be used as a supplement to the drive user manual. For information regarding drive programming and operation, refer to the 160 SSC™ Variable Speed Drive (Series C) User Manual, Publication 0160-5.17ML. Exceptions to Drive User Manual Important: Set P42 - [Motor Overload Current] to motor nameplate full load amps (FLA). Settings that are not within Min / Max levels will cause premature failure of the product.
2 160-NX3 Series C Drive Control Inputs Control Input Type For dry contact closure input - drive has an internal 12V power supply that provides 10mA (typical) current. Also accepts open collector/solid-state input with maximum leakage current of 50µA. Optional 24V DC interface allows use of 24V DC “sink logic” inputs.
160-NX3 Series C Drive 3 Protective Features Overcurrent 200% hardware limit (16 amps), 300% instantaneous fault (24 amps) Excessive Temperature Embedded temperature sensor trips if heatsink temperature exceeds 95 degrees C (203 degrees F) Over Voltage Drive Rated Input = 200-240V AC Drive Rated Input = 380-460V AC DC Bus voltage is monitored for safe operation Overvoltage trip occurs at 400V DC bus voltage (equivalent to 290V AC incoming line voltage).
4 160-NX3 Series C Drive Installation ! ! ! ATTENTION: To guard against electrical shock, disconnect from power source before installing or servicing. ATTENTION: Do not touch drive surfaces. Temperatures are hot enough to cause severe burns. ATTENTION: After system installation, remove the debris label from the unit. Failure to remove this label may result in overheating or nuisance tripping. Cut-out and Mounting Detail For Customer Panel 1 8 (0.31) ∅ 5.5 (0.22) 6 Holes 114 (4.49) (Heatsink) 195 (7.
