2.4.2
7026TX
The 7026TX has a redundant 18-49 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 switch before powering on the unit.
Note:
LEDs are described in detail in
.

AC
The 7026TX-AC has 90-264 VAC/90-300 VDC power input.
1.
Unscrew and remove the DC voltage input plug from the power input header.
2.
Install the DC power cables into the plug (observing polarity).
3.
Plug the voltage input plug back into the power input header.
This is the
power disconnect device that must be removed before performing any kind of
service or maintenance on the device.
4.
Tightening torque for the terminal block power plug is 0.5 Nm/0.368 lb/ft.
5.
Verify that the power LED is on (Green).
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 current from both sources
simultaneously. Use 16-28 AWG (0.08mm
²
- 1.31mm
²)
wire when connecting to the power
supply.
