Notes
for
NT24k
PoE
models
•
NT24k PoE models, use 12-14 gauge solid or stranded wire with ferrules.
•
Voltage drop across the power wires between the source power supply and the NT24k unit should be
considered during installation. (~0.5V/10ft for 12 AWG wire, ~0.65V/10ft for 14AWG).
•
Failure to use proper wire may cause the following:
•
Unit does not power up properly or may cycle power on/off.
•
PoE ports being shut off
•
Excessive heat on the wire conductors may cause permanent damage.
•
Verify that the proper input voltage is connected to the NT24k before powering on the unit.
Never apply AC
power to a DC NT24k unit as it will permanently damage the unit.
