2.3 Power Source
Non-PoE Models
The NT24k non-PoE (Power over Ethernet) models come with a redundant 10-49 VDC power input.
Recommended 24 VDC power supply, similar to Red Lion’s P/N NTPS-24-1.3.
Verify that the proper input voltage is connected to the NT24k before powering on the unit. Applying AC power to a
DC NT24k unit will damage the unit.
Note:
LEDs are described in detail in
“LEDs” on page

.
•
Unscrew and remove the DC voltage input plug from the power input header
•
Install the DC power cables into the plug (observing polarity)
•
Plug the voltage input plug back into the power input header
•
Tightening torque for the terminal block power plug is 0.5 Nm/0.368 lb/ft
•
Verify that the power LED is on
Note:
When a DC power supply is installed, only one power supply must be connected to power for minimal
operation. For redundant power operation, V1 and V2 inputs must be connected to separate DC voltage
sources. This unit will draw power from the supply with higher voltage. Use 16-28 gauge wire when
connecting to the power supply.
