1. Locate the nine (9) 2-1/4" aluminum standoffs in the installation kit and screw one securely
into each of the nine (9) threaded PEMs in the back surface of the enclosure.
2. Slip on a wrist ground strap and clip the ground strap to the earth ground in the enclosure.
Do not remove the PCB from its shipping carton unless you have established a common
earth-ground potential among yourself, the enclosure, and the PCB's shipping carton.
3. Remove the PCB from its shipping carton and position each of its nine (9) mounting holes
over one of the aluminum standoffs so that the AC-input terminal block is in the lower-left
corner.
4. Secure the PCB to the standoffs using the eight (8) short washer-and-screw assemblies
supplied in the installation kit.
Note: Do not tighten the screws at this time.
The PCB mounting hole in the lower left corner utilizes a longer nylon screw that also holds
the AC Safety Cover in place. See Section 2-7.1.
5. Refer to Figure 2-7 and place the free end of the longer of the two factory-installed Earth-
Ground wires under the screw assembly of the main printed-circuit board as shown before
tightening. Tighten the remaining eight screws. Be careful not to over-tighten.
6. Plug the harness from the power-supply unit into Connector J12 in the lower-left-hand
corner of the PCB.
