Installation Chapter 2

Follow these steps to connect the computer to a DC power source.

1. Turn off the main power switch or breaker.

2. Verify that the DC wires meet these requirements:

• Material: Stranded copper

• Wire gauge: 0.325…0.823 mm

2

(22…18 AWG)

3. Secure the DC power wires

to the correct terminal-

block screws, and the DC

ground wire to the GND

terminal screw.

Torque the terminal screws

to 0.687 N•m (6.1 lb•in).

4. Apply 24V DC power to the

computer.

Functional Ground Screw

The pre-installed functional ground screw is not required for safety or regulatory

compliance. However, if a supplemental ground is desired, use the functional

ground screw located in the I/O area on the side panel of the computer.

If using the functional ground screw, connect the computer to earth ground by

using a 1.5 mm

2

(16 AWG) or larger external wire. Use a ground wire with green

insulation and a yellow stripe for easy identification.
