6300B-MM Machine Mount Box PCs Installation Instructions
Install the Ground Wire (optional)
Figure 4 - Assembly Sequence of Ground Wire
1. Be sure that the main power switch or breaker is still turned off.
2. Identify the location of the pre-installed functional ground screw
(see (1) in Figure 3 on page 6).
3. Remove the supplied nut, eyelet terminal, and washers from the ground
screw.
4. Attach a 2.5 mm2 (14 AWG) or larger external wire to the eyelet terminal.
5. Strip 5 mm (0.2 in.) from the covering at the end of the grounding wire.
6. Insert the stripped end of the grounding wire into the open end of the
eyelet terminal, and crimp it securely to the wire.
7. Install the ground wire and washers to the ground screw. See Figure 4 for
assembly sequence.
8. Reinstall the ground screw to the computer chassis.
Complete the Initial Setup
1. Verify that your input power does not exceed the UL rating of
100…240V AC, 50/60 Hz, 1.5 A…0.6A.
2. Connect the AC power cord (supplied) to a power source with an earth
ground.
3. Apply AC power to the machine mount box PC.
The default UEFI setting will automatically start your machine mount box
PC when you connect power to your machine mount box PC for the first
time.
4. For machine mount box PCs using the Windows® operating system (OS):
Read and accept the End-User Setup procedure.
Additional Resources
This publication provides basic installation instructions. For more information, see
the following Rockwell Automation publications at rok.auto/literature.
The pre-installed functional ground screw is not required for safety
or regulatory compliance.
If you want a supplemental ground, complete the following steps.
Otherwise, proceed to Complete the Initial Setup.
Use a grounding wire with an insulation color that is
approved by your local inspection authority.
We recommend that the computer circuit be supplied with
its own disconnect.
Use an uninterruptible power supply (UPS) to help protect
against unexpected power failure or power surges.
SHOCK HAZARD: Failure to connect the supplied AC power
cord to a power source with an earth ground can result in
electrical shock.
Do not allow your input power to exceed the UL rating of
100…240V AC, 50/60 Hz, 1.5 A…0.6A.
ATTENTION: (1) Do not disconnect power from the
system until after the Windows® Setup procedure is
completed. If power is disconnected during this
procedure, it can result in a corrupted system image.
(2) To minimize performance degradation and OS
failures: always shut down the Windows OS before you
disconnect power to the PC.
