What would cause a Quantum 140CPS11100 power supply to not power up?



The Quantum 140CPS11100 power supply that has a PV 01 or higher now require a jumper on pins 3 and 4 on the terminal strip for 115 VAC operations. If this jumper is not installed, it will be set for 220 VAC operations. Any power supply with a PV less than 1 did not require the jumpers.

Note: The Quantum line is obsolete 12/1/2018 and the recommended replacement is the M580 with the x80 I/O, for further information on this contact your local distributor.
