NX-Platform Hardware Installation and Safety
Caution:
Do not attach a ground wire to the ground screw on the DC power supply module. Attach
the ground wire to the NX-Platform chassis DC grounding screw holes (0.63-inch hole
spacing) with #10 screws. The DC grounding screw holes are located in the rear of the NX-
Platform chassis. Refer to the preceding image.
The Status LED is green when the module is powered and running normally.
When the DC power supply has been securely placed in the device, use the following procedure to connect
power to the DC power supply:
1. Locate the ground screw on the back of the chassis.
2. Attach a 12 AWG ground wire to the chassis ground strap mounting.
The wire should be crimped with a ring lug.
3. Locate the power input terminal block on the back of the module.
4. Attach the 12 AWG DC power wires to the power input terminal block labeled -48V and RTN.
The power wires should be crimped with lug spades to ensure a secure connection.
5. Connect the other side of the power cable to the SELV power source.
The power source should meet the following requirements:
• Voltage: -40 to -60 V
• 24 – 16 Amps
• SELV
6. The NX-Platform device returns to its previous power-on state in the event of a power interruption.
If power was on when the interruption occurred, the device automatically powers back on when the
power is reconnected; if power was off, the device stays off when the power is reconnected. If necessary,
power on the device with the button on the front of the chassis.
