Procedure D: Installing the new PSU Bracket.
In some cases the engraver’s Power Supply Unit (PSU) will need to be rotated to accommodate the new
laser tube. This procedure illustrates the process to rotate the PSU and install a new mounting bracket.
This procedure is only for engravers with the Power Supply Unit (PSU) illustrated in Figure A. If your
engraver has a power supply unit matching Figure B or Figure C than you may skip this procedure.
Please contact Epilog Technical Support if you need assistance.

The Power Supply Unit (PSU) may contain hazardous electrical current. Please exercise caution any time
you work with Mains power. Be sure that the engraver is Powered Off and Unplugged before starting
work on the PSU. Do not touch Electrical Contacts, Leads, or Damaged Wires with your bare hands
while performing this procedure. Do not attempt to open the PSU’s housing.
Electrical charge may still be present in the PSU even after it has been disconnected.
