The instructions which follow pertain to installation of additional ARIES NETLink equipment, not included in the standard system shipping carton.
2-7.1 Installing the Expansion Card Cage
To install the Expansion Card Cage:
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 Card Cage assembly.
2. Verify that all power sources intended to provide power to the control unit are removed.
3. Slip on a wrist ground strap and clip the ground strap to the earth ground in the enclosure. Do not remove the Card Cage from its shipping carton unless you have established a common earth-ground potential among yourself, the enclosure, and the Card Cage’s shipping carton.
4. Remove the Card Cage Assembly from its packaging.
5. Locate the two 8/32” nuts provided in the hardware kit.
Note: To get access to the PMU board power connectors, it is recommended that the MCB be opened. This requires disconnecting power and COM harnesses from the MCB and field wiring plugs as required, then removing the four mounting screws and opening the (hinged) MCB.
6. Locate the three retention tabs in the enclosure’s back panel (found at the bottom).
7. Orient the Card Cage as shown in Figure 2-18 below.
8. Grasping the Card Cage with both hands, align the top slots with the studs in the enclosure and insert the bottom into the two outermost retention clips.
9. Gently hold the Card Cage in place and insert the two nuts with a nut driver.
10. Connect the 5-in. ground wire harness (attached to the backplane) to the Earth Ground stud located at the right of the enclosure.
11. Connect the DC power harness from connector J9 on the backplane to either J4 or J5 connectors on the PMU Board.
12. Connect the COM harness from connector J10 on the backplane to connector J9 on the MCB.
Note: If this is the only Card Cage in the entire ARIES NETLink system, insert an End-of-Line Terminator into connector J11 on the backplane.
13. Remove wrist ground strap.
14. Lastly, if the MCB was opened to gain access to PMU power connectors, close the MCB and replace all connections/field wiring previously disconnected. Replace screws to secure board.
CAUTION
Use a ground strap to prevent static discharge that could damage sensitive components on the PCBs.

2-7.2 Inserting and Securing an Expansion Card
To install a card into a Card Cage slot:
1. Make sure the enclosure location is dry and that the enclosure is free of construction dust and metal shavings prior to installing the card.
2. Slip on a wrist ground strap and clip the ground strap to the earth ground in the enclosure. Do not remove any card from its shipping carton unless you have established a common earth-ground potential among yourself, the enclosure, and the shipping carton.
3. Remove the card to be inserted from its packaging.
4. Insert the card into the desired slot and push gently to ensure a good connection with the backplane connector.
Note: Cards can be plugged into any slot in the Expansion Card Cage. There are no reserved slots.
Refer to Section 1-13.1, General Guidelines for the Use of Expansion Cards, for more information on the use of expansion cards.
5. Locate two #8 mounting screws in the hardware kit.
6. Orient the card as shown in the Table 1-3 illustration column (in Chapter 1).
7. Insert the two mounting screws into the top and bottom mounting holes and tighten securely.
8. Remove wrist ground strap from enclosure.
Note: If installing an R-NAC card, connect the DC power harness from connector J8 on the R-NAC card to any available connector (J12 through J18) on the backplane.

CAUTION
Use a ground strap to prevent static discharge that could damage sensitive components on the PCBs.
2-7.3 Installing Add-On Power Supply/PMU Assembly With Bracket
To install an Add-On Power Supply/PMU Assembly into any 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 power supply.
2. Remove the Power Supply/PMU Assembly from its packaging.
3. Locate two #8 Phillips-head mounting screws in the hardware kit.
4. Ensure that the AC-input-voltage selector switch on the power supply unit(s) is set to the proper position for either 115 Vac or 230 Vac. Refer to Figure 2-4 in Section 2-4.3 for location of the selector switch.
5. Orient the Power Supply/PMU Assembly with the power supply unit(s) to the left, as shown below in Figure 2-20.
6. Locate the retention tabs in the enclosure’s back panel.
7. Grasping the assembly with both hands, slide the assembly onto the two outermost retention tabs.
8. Gently hold the assembly in place and insert one of the top mounting screws; hand-tighten.
9. Repeat for the remaining screw and tighten both screws securely.
10. On the PMU Board, locate the right topmost screw (beside the AC power input connector).
Remove the screw, attach the 5-in. ground wire assembly and tighten. Connect the other end of the ground wire assembly to the Earth Ground stud located at the right of the enclosure.
11. Remove ground strap.
12. Connect the COM harness from connector J12 on the Add-On Power Supply/PMU Assembly to J13 of the installed PMU Board.

CAUTION
Use a ground strap to prevent static discharge that could damage sensitive components on the PCB.
2-7.4 Installing the Battery Tray
The battery tray (P/N 76-800030-006) fits securely into the bottom tier of a Main or Expansion Enclosure and serves to support the batteries while providing easy access to wiring at the bottom of the enclosure.
Note: Insertion of the battery tray is not necessary if knockouts at bottom of enclosure will not be used.
To install the battery tray, do the following:
1. Remove the battery tray from its packaging.
2. In the bottom tier of the enclosure, locate the three retention tabs in the enclosure’s back panel.
3. Orient the tray such that its vertical lip is facing the front of the enclosure, as shown in Figure 2-21.
4. Grasp the tray with both hands and insert the back of the tray into the retention clips.
5. Push down firmly to ensure that the tray is securely seated.

2-7.5 Connecting Standby Batteries To PMU Board
Note: Observe polarity when connecting batteries to the control unit.
To connect the standby batter(ies)to the control unit:
1. Calculate the size of the battery required for the application. Refer to Appendix A for the proper procedure.
2. Connect two or more 12-volt, series-wired batteries of the required ampere-hour (AH) capacity to Terminal J10 on the PMU Board using battery cables found in the PMU Board hardware kit. See Figure 2-22 below.
Figure 2-22. Standby Battery Connections
WARNING
Batteries contain sulfuric acid that can cause severe burns to the skin and eyes and can damage clothing. Immediately flush areas of the skin or eyes that have been contacted with sulfuric acid for 15 minutes with water and seek medical attention promptly.
