Installation Guidelines
Follow these steps to install the 140CPS12400 power supply:
Turn off all power to the Quantum rack before installation.
Slide the 140CPS12400 into the dedicated power supply slot.
Secure the module with the top and bottom retaining screws.
Connect the AC input wires to the correct terminals (L, N, and ground).
Install a 2 A slow-blow external fuse on the line side.
Verify the green PWR OK LED lights up after power-on.
Do not mix redundant and non-redundant supplies in the same rack. Use two 140CPS12400 modules for true redundant configuration. Keep ventilation holes clear for proper cooling.
Packaging List
Power Dissipation Reference
The 140CPS12400 generates heat based on your load current. Use this formula to estimate thermal output:
Power Dissipation (W) = 6 + (1.5 x Iout)
Example at 4 A load: 6 + (1.5 x 4) = 12 W
Example at 8 A load: 6 + (1.5 x 8) = 18 W
Proper cabinet ventilation must remove this heat for reliable operation.
Common FAQs
Q1: Can I use the 140CPS12400 as a single non-redundant supply?
A1: Yes, the 140CPS12400 works as a standalone power supply. You simply leave the second slot empty.
Q2: What happens if the 140CPS12400 loses one AC input phase?
A2: This module only accepts single-phase AC input. A complete loss of power shuts down the 140CPS12400 output.
Q3: How do I wire two 140CPS12400 modules for redundancy?
A3: Install two 140CPS12400 modules side by side. Connect each to a separate AC source. The Quantum backplane handles load sharing automatically.
Q4: Does the 140CPS12400 work with 110V DC input?
A4: No, the Schneider Electric 140CPS12400 accepts AC input only. Use model 140CPS11420 for 125V DC applications.
Q5: What size external fuse protects the 140CPS12400 best?
A5: Schneider Electric recommends a 2 A slow-blow fuse for the 140CPS12400. Install this fuse on the AC line input wire.
