Mounting CutoutThe following figure provides the dimensions for making the panel orenclosure cutout. If you are using mounting clips, the mounting studs areremoved and the 18 stud holes are not necessary.



Panel Mounting (with Studs)

ATTENTION: Disconnect all electrical power from thepanel before making cutout.

Make sure the area around the panel cutout is clear.

Take precautions so that metal cuttings do not enter anycomponents that are already installed in the panel.

Failure to follow these warnings may result in personalinjury or damage to the panel components.

To install the RAC6180 in a panel using 18 mounting studs:1. Cut an opening in the panel using the panel cutout dimensions

provided on page 10. Carefully drill eighteen 7/32-inch (5.6 mm)holes for studs as indicated.

2. The 18 mounting studs are factory installed. In the event studs wereremoved for clip mounting, you can re–install studs using a 1/8 inchsocket on the end of the stud. Turn stud clockwise to tighten toapproximately 10 inch-pounds (1.1 N•m).

ATTENTION: Be careful not to damage the sealinggasket when installing or removing studs. A damagedseal may result in damage to the RAC6180 and otherpanel components due to a leaking seal.

3. Make sure the sealing gasket is properly positioned on the terminal.This gasket forms a compression type seal (NEMA Type 4x). Do notuse sealing compounds.

4. Place the RAC6180 in the panel cutout aligning the studs with themounting holes. The RAC6180 will snap into the panel as thetemporary retaining tabs lock against the panel (see note following).

Note: Versions of the RAC6180 designed for panel mountinghave metal tabs that temporarily lock the RAC6180 againstthe panel. These tabs only facilitate installation of themounting hardware. The tabs are not designed to providepermanent mounting.

5. Install the 18 self–locking nuts hand tight.

ATTENTION: Tighten mounting nuts to a torque of 10inch pounds (1.1 N•m) to provide a proper seal andprevent damage to the RAC6180. Rockwell Automationassumes no responsibility for water or chemical damageto the terminal or other equipment within the enclosurebecause of improper installation.



6. Alternately tighten the self–locking nuts (use 3/8 inch socket) until theRAC6180 is held firmly against the panel (see recommendedtightening sequence below). The studs have an integral spacer thatprevents the gasket from being over–compressed. The amount oftorque required increases significantly as the gasket reaches the propercompression. Tighten nuts to a torque of 10 inch–pounds (1.1 N•m).

Note that sequence starts at center studs and continues to the corner studs.



Panel Mounting (with Clips)

ATTENTION: Disconnect all electrical power from thepanel before making cutout.

Make sure the area around the panel cutout is clear.

Take precautions so that metal cuttings do not enter anycomponents that are already installed in the panel.

Failure to follow these warnings may result in personalinjury or damage to the panel components.

To install the RAC6180 in a panel using mounting clips:1. Cut an opening in the panel using the panel cutout dimensions

2. If the mounting studs are present, they should be removed. To removea stud, use a 1/8 inch socket and turn counterclockwise to remove.

ATTENTION: Be careful not to damage the sealinggasket when installing or removing studs. A damagedseal may result in damage to the RAC6180 and otherpanel components due to a leaking seal.

3. Make sure the RAC6180 sealing gasket is properly positioned on theterminal. This gasket forms a compression type seal. Do not usesealing compounds.



4. Place the RAC6180 in the panel cutout. The RAC6180 will snap intothe panel as the temporary retaining tabs lock against the panel (seenote below).

Note: Versions of the RAC6180 designed for panel mountinghave metal tabs that temporarily lock the RAC6180 againstthe panel. These tabs only facilitate installation of themounting hardware. The tabs are not designed to providepermanent mounting.

5. Install the 10 mounting clips (Catalog No. 2711–NP1). The mountingclips slide into the slots on the sides, top and bottom of the RAC6180as indicated by the arrows shown on the following diagram (3 top, 3bottom, 2 sides). Gradually tighten the clips one at a time around thebezel (see tightening sequence below). Repeat this process at leastthree times until the clips are hand tight and the gasket is compresseduniformly against the panel.

6. Tighten mounting clips to a torque of 10 inch–pounds (1.1 N•m) in thesequence shown above. Do not over–tighten.

ATTENTION: Tighten mounting clips to a torque of 10inch pounds (1.1 N•m) to provide a proper seal andprevent damage to the RAC6180. Rockwell Automationassumes no responsibility for water or chemical damageto the terminal or other equipment within the enclosurebecause of improper installation.

Note: The mounting clips on the hinge side interfere with theopening of the hinge. Remove the clips before opening thehinge.



Rack MountingThe RAC6180 mounts in a standard EIA 19 inch (48.3 cm) rack. TheRAC6180 occupies 8U EIA units.

Rack Mounting GuidelinesObserve the following precautions before installing the RAC6180 in arack:

ATTENTION: Disconnect all electrical power from therack before installing the RAC6180.

If installing the RAC6180 in an enclosed rack, make surethe ambient temperature stays within 5° to 50° C (41° to122° F). Be aware of other nearby devices which mayraise the ambient temperature in the rack. Make surethere is adequate room for air flow through the RAC6180chassis vents.

Verify that the addition of the RAC6180 does not causeuneven loading (instability) of the rack.

Check that the power supply limits for the rackcomponents will not be exceeded by the addition of theRAC6180.

Make sure the installation of the RAC6180 maintainsproper earth grounding of the rack components. TheRAC6180 requires connection to a power source havingan earth ground (three prong outlet).

Failure to follow these warnings may result in personalinjury or damage to the rack components.



To install the Plastic Bezel versions of the RAC6180 in a rack:

Note: The metal bezel versions of the RAC6180 have mountingholes in the bezel. User must provide rack mountinghardware (see example illustrated next).

1. The 18 mounting studs are factory installed. In the event studs wereremoved for clip mounting, you can re–install studs using a 1/8 inchsocket on the end of the stud. Turn stud clockwise to tighten toapproximately 10 inch pounds (1.1 N•m).

Figure 10Rack mounting procedures

2. Place the RAC6180 in the rack aligning the studs with the mountingholes.

3. Install the 8 self–locking nuts hand tight.

4. Alternately tighten the self–locking nuts until the RAC6180 is heldfirmly against the rack. Tighten nuts to a torque of 10 inch–pounds(1.1 N•m).



Connecting a Mouse & KeyboardThe mouse and keyboard plug directly into the side panel mouse andkeyboard ports. When connected to the processor board ports, it does notmatter if the keyboard and mouse cables are interchanged, because theRAC6180 will automatically detect them.

Jumper ports forfront panel connectors

Make sure you use the mouseand keyboard ports on the processorboard, not the jumper ports for thefront panel connectors.

Power ConnectionsConnecting Power to a RAC6180 AC UnitA standard IEC 320 power cord provides power to the RAC6180. Thepower supply input will accept 120/240V AC.

ATTENTION: If the power supply has a manual inputvoltage selection switch, check voltage selection beforeapplying power.

ATTENTION: The power cord must be connected to anoutlet having an earth ground (three prong outlet). Failureto follow this warning could result in severe electricalshock.



Use the cord retainer to prevent accidental interruption of power to theRAC6180. Pull the cord retainer over the cord plug as shown below. Thefollowing illustration pertains to RAC6180 computers equipped with aPentium Class CPU1.

Figure 13RAC6180 power cord retainer

1 The power cord connector is recessed on RAC6180 computers equipped with aPentium III CPU.



Connecting Power to a RAC6180 DC UnitRAC6180 Industrial Computers can be equipped with a DC power supply.It is recommended that the 24V DC power be supplied via 10 or 12 gaugewiring kept as short as possible, preferably less than 3 meters in length.

ATTENTION: Proper Earth grounding of the productchassis is required when using the 200W DC input powersupply. Keep the grounding wire short, and preferablyuse braided cable, in order to reduce the impedance of thisconnection as much as possible. Improper grounding willresult in reduced immunity to line transients and surgeson the DC input power lines.

The RAC6180 with a DC power supply is supplied with a terminalconnector that simplifies connecting power to the unit (see diagram onpage 27). You connect the wires to the terminal connector, and then plugthe terminal connector into the terminal block on the unit.

ATTENTION: Ensure that the wires are correctlyconnected to the terminal connector. Failure to correctlywire the connector could result in severe electrical shockor damage to the unit.



Figure 14RAC6180 DC power terminal connector



Configuring the Power Supply Jumper

The RAC6180 120/240VAC power supply can be configured to eitherpower up using the on/off switch or to automatically turn on when ACpower is applied to the unit. An internal jumper on the power supplywiring harness controls the configuration. The factory default settingenables the on/off switch. To change the configuration, perform thefollowing steps:

1. Remove power from the RAC6180. Disconnect the power cord.

2. Remove the RAC6180 back cover. Locate the power supply, and lookfor a single white wire not connected on the power supply wiringharness. The white wire is shipped not connected from the factory,because this position enables the power switch to be used.

3. If the power switch bypass mode is desired, then connect the whitewire to its mating connector.

4. Replace the back cover. Reconnect power to the RAC6180.

5. Press and hold the on/off switch for at least 10 seconds.

6. Unplug the RAC6180 and wait 5 seconds before plugging back in.This clears the soft-start logic on the RAC6180 motherboard.

7. Plug in the unit again. The on/off switch bypass mode is enabled.

When using Microsoft Windows NT, a normal shut down and power cyclewill restart the computer regardless if the computer needs the power buttonturned back on; steps 2 and 3 need to return to bypass mode. A poweroutage in Windows 95/98 will still automatically reboot the computer.



Replacing the BatteryThe RAC6180 contains a battery to maintain the CMOS settings and real-time clock. The battery is located in a battery holder on the RAC6180backplane. Replace this battery as needed with a Panasonic battery, partnumber CR2032.

ATTENTION: There is a danger of explosion if thebattery is incorrectly replaced. Replace only with thesame or equivalent type recommended by themanufacturer. Dispose of used batteries according to themanufacturer's instructions.
