The power supply is internally protected against reverse polarity.
Follow these steps to connect the computer to a DC power source.
1.
Verify the main power switch or breaker is off.
2.
Verify that the DC power 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 terminal block screws, and the ground wire to the
GND terminal screw.
Tighten the terminal to a torque of 0.687 N•m (6.1 lb•in).
4.
Apply 18…32V 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 in the I/O port panel of the computer.
If using the functional ground screw, connect
the product to earth ground by using
a 1.5 mm (16 AWG) or larger external wire.
Use a ground wire with green insulation and a
yellow stripe for easy identification.
ATTENTION:
Use a SELV isolated and ungrounded power supply as input power to the computer.
This power source provides protection so the voltage between the conductors and functional
earth/protective earth does not exceed a safe value under normal and single fault conditions.
