1.1.
Kit 08PSS3401X (for Newer Machines)
—Merely swap out the old with the new power
supply. Make certain that a good connection is established between the ground trace on the
power supply board and the machine chassis, as shown in Figure 1. If the new power supply is
not a direct match for the old, contact the Milnor factory.
1.2.
Kit 08PSS3401N (for Older Machines)
—Various mounting brackets are supplied with
this kit. If your original equipment does not accommodate the new power supply, select the
mounting configuration that permits you to mount the new power supply in approximately the
same position as the old one.
The mounting hardware supplied with the kit attaches the power supply to its mounting bracket.
Hardware to attach the mounting bracket to the machine is not supplied with the kit. Use any
appropriately sized bolts, nuts and lock washers or self-tapping screws.
Recommended hardware installation is as follows:
1. If a mounting bracket will be used, determine how it will be attached. Carefully prepare the
Processor box as required to accept it, but do not install it until step 3.
2. Attach the power supply to the mounting bracket or directly to the Processor box, as shown in
Figure 1. One of the four bolts supplied with the kit is metallic. This bolt must be placed in
one of the two grounded mounting holes on the power supply ( hole through a metallic trace
on the power supply's printed circuit). Ensure that the power supply is grounded to the
mounting bracket or Processor box by scraping the paint from around the hole on the bracket
or box with the metallic bolt. Be sure the metal nut and lock washer do not touch any other
component.
