Installation Guidelines
Follow these steps to install your Schneider Electric 140DAI34000 module correctly.
Power Down the Rack – Turn off all power to the Quantum backplane.
Select the Slot – Choose an available slot in the backplane.
Insert the Module – Slide the 140DAI34000 into the selected slot.
Secure the Module – Tighten the top and bottom retaining screws.
Wire Inputs – Connect 24V AC field devices to the input terminals.
Verify Voltage – Confirm input voltage is between 16V and 30V AC.
Apply Power – Turn on the rack power and check the green Active LED.
Test Inputs – Toggle each field device and verify the green input LEDs.
Do not exceed 30V AC continuous on any input channel. Higher voltage will damage the module.
