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: 14…18 AWG
3. Secure the DC power wires to the terminal block screws.
Tighten the terminal to a torque of 0.687 N•m (6.1 lb•in).
4. Secure the ground wire by using a ring style connector to the functional earth terminal
screw.
Tighten to a torque of 1.47 N•m (13 lb•in).
5. Apply 18…32V DC power to the computer.
IMPORTANT When using the functional ground screw, connect the product to earth ground
by using a 1.5 mm
