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.
