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
hardware that permits you to loacte the new power supply about where the old one was.
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 (hole through a metallic trace on the power supply's
printed circuit) on the incoming power side of the power supply. 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.
3. If a mounting bracket was used, install this assembly in the Processor box. Ensure that the
mounting bracket is grounded to the Processor box by scraping the paint from around one
pair of adjoining mounting holes on the bracket and the Processor box.
