1.
Unscrew & Remove the DC Voltage Input Plug from the top header.
2.
Install the DC Power Cables into the Plug (observing polarity on unit).
3.
Plug the Voltage Input Plug back into the top header.
4.
Tightening torque for the terminal block power plug is
0.5 Nm/0.368 Pound Foot
.
5.
Verify the Power LED stays ON (GREEN).
Note:
Either V
1
or V
2
can be connected to power for minimal operation. For redundant power
operation, V
1
and V
2
plugs must be connected to separate DC Voltage sources. Use wire sizes of 12-
24 gauge for non-PoE models and 12-16 gauge for PoE models . Limit the power cord length to less
than 10 meters in order to ensure optimum performance.
Recommend using 24V DC Power Supplies, similar to:
•
100-240VAC: N-Tron NTPS-24-1.3, DC 24V/1.3A
•
100-240VAC: N-Tron NTPS-48-5, DC 48/5A Ground Connection
•
100-240VAC: N-Tron NTPS-24-10, DC 24V/10A
Ground Connection
N-Tron Series Switch Grounding Techniques for 1000 Series
The grounding of any control system is an integral part of the design. Optimum noise immunity and emissions are
obtained when the chassis is connected to earth ground via a 12-14 gauge drain wire. The N-Tron series models
provide a ground lug that is used to provide a safe grounding path of the device.
