2-4.7 Installing the Main Controller Board into Enclosure Top Tier
Note: The top tier of the enclosure has been designed to accommodate two power supply units and
a Power Management Unit (PMU) Board. Power supply units and PMU Board must be
installed first, followed by the Main Controller Board with Keypad/Display which fits over
these components.
To install the Main Controller Board (MCB) with Keypad/Display into the top tier of an enclosure:
1. Make sure the control unit location is dry and that the enclosure is free of construction dust and
metal shavings prior to installing the MCB.
2. Slip on a wrist ground strap and clip the ground strap to the earth ground in the enclosure. Do
not remove the MCB from its shipping carton unless you have established a common earth-
ground potential among yourself, the enclosure, and the MCB’s shipping carton.
3. Remove the MCB from its packaging.
4. Locate the four 2-1/4 in. aluminum standoffs in the hardware kit and, using a nut driver, screw
one securely into each of the four threaded studs in the back surface of the enclosure. Refer to
Figure 2-13.
5. Orient the MCB such that its raised metal edge is on the left side.
6. Grasp the board at a 45-degree angle (to clear the upper bracket) and lift upwards to insert the
board’s topmost metal tab into the top hinge. Next, insert the board’s bottom metal tab into the
bottom hinge.
Note: Before securing the MCB, for ease of access, it is recommended to fully open the MCB and
connect internal power and communication connections. Refer to Figure 2-15 and
Figure 2-16 for an overview of power and communication connections.
7. Insert COM harness (supplied in MCB hardware kit) from connector J2 on the MCB to connector
J12 on the PMU Board.
8. Insert a 24Vdc power cable (supplied in MCB hardware kit) from connector J10 on the MCB to
connector J3 on the PMU Board.
9. If applicable, insert a terminal block onto the AUX power output (J9) on the PMU Board and
install auxiliary power and standby battery wiring.
10. Connect the dangling end of the Audible PMU Trouble Sounder harness from the PMU Board to
connector J1 on the back of the Keypad/Display PCB (small black connector above buzzer).
11. With connections made, gently push the MCB in place so that it pivots on its hinge and lays flat
on top of the four aluminum standoffs.
12. Locate the four #8 Phillips mounting screws in the hardware kit.
13. Insert the three remaining mounting screws into the standoffs; tighten securely.
14. Connect the other end of the MCB ground wire harness (dangling from the Earth Ground stud
on enclosure) to the top right standoff in the corner of the MCB with a #8 mounting screw.
15. Complete connection of power and COM harnesses from PMU to MCB.
16. Remove wrist ground strap.
CAUTION
Use a ground strap to prevent static discharge that could damage sensitive components
on the main PCB.
