FRONT PANEL

1. MOUNTING

The AC 120 provides four standard single space rack mounting holes. All four screws should be used to secure the unit in the rack. The best placement for the AC120 in the rack is at the top so the lamps can shine down on the rest of the gear in the rack.

2. LAMP SWITCH

The Lamp switch is off in the center position. Press the lamp switch up for HIGH illumination and push down for LOW illumination.

3. LAMPS

To use the lamps, pull the tubes out and position as needed. The lights will normally project downward.

4. SAFETY GROUND INDICATOR

The green SAFETY GROUND LED indicator will be illuminated if the AC120 is plugged into a wall socket providing a solid Earth Ground. If the green LED is not on, this indicates that the gear plugged into the AC120 is not connected to Earth ground. Make sure the SAFETY GROUND indicator is illuminated. Equipment that is not properly grounded introduces the risk of electric shock.

5. LINE VOLTAGE METER

The LINE VOLTAGE METER consists of 16 LED’s measuring the incoming AC voltage from 100VAC to 130VAC in two volt increments. The LED’s indicate the RMS voltage level of the wall outlet or junction box. This is the same voltage being supplied to the gear plugged in to the AC120. By monitoring the voltage level, you will be assured the AC line voltage is in a safe operating range for your gear.

6. POWER SWITCH

The power switch will be illuminated when the unit is plugged in and turned on.

REAR PANEL

8. AC POWER

The AC120 is designed to run on 120V 60Hz. Never defeat the grounded connection or electrocution may result!

9. CIRCUIT BREAKER

A 15A circuit breaker is provided for over current protection.

10. AC OUTLETS

The rear AC outlets have been positioned to allow for up to four “wall-warts” and four standard spaced plugs to be used simultaneously. Before plugging gear into the AC120, check voltage level on the LINE VOLTAGE meter and verify that it is in the safe range specified by the gear manufacture. Also be sure to verify that the green SAFETY GROUND indicator is illuminated.

RECEIVING INSPECTION

INSPECT YOUR ITEM FOR ANY DAMAGE which may have occurred during

shipping. If any damage is found, please notify the shipping company & CARVIN.

SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to reship your unit, always use the original carton and packing material. This will provide the best possible protection during shipment. CARVIN and the shipping company are not liable for any damage caused by improper packing.

SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.

SHIPMENT SHORTAGE. If you find items missing, they may have been shipped separately. Please allow several days for the rest of your order to arrive before inquiring.

RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual for your records. Keep your portion of the card and return the portion with your name and comments to us.

For your records, you may wish to record the following information.

AC120 shown in rack case with lamps extended

The AC120 is designed to be a safe, convenient power distribution point for your rack-mounted gear. The AC120 offers several protection devices to protect all gear plugged into it. The first form of protection are the TRANSIENT/SURGE ABSORBERS removing over voltage spikes on the AC lines from other gear and appliances. Next is the 15 AMP EMI FILTER reducing RF and other noise elements on the AC lines coming in. The AC120 provides two visual indicators on the front panel for further protection. The first of these is the LINE VOLTAGE Meter displaying the incoming voltage in 16-segments from 100-130 VAC. The other is the

SAFETY GROUND indicator which illuminates when EARTH grounded is present. The AC120 also comes complete with two retractable lamps. The retractable lamps provide light for all the rest of the gear in the rack with two brightness settings. The AC120 has been designed to accommodate up to four “wall-warts” and four standard spaced plugs. The AC120 is a durable unit constructed of 18 GA steel and ready for the road. You’ll find the AC120 Power Conditioner an invaluable addition to your rack.

NOTE: The AC120 is fitted with a 15AMP circuit breaker so the maximum total

current available to the all eight outlets is 15AMPS. A maximum of one high

powered amplifier can be plugged into the AC120 (such as DCM1000’s and

larger).

For Lamp replacement do, the following:

1. Turn off the AC120 and let lamp tubes cool if needed.

2. Extend light tube.

3. With one hand, hold on to the tube.

4. With the other hand, hold tube cap, turn cap clockwise one click and pull cap off.

5. With finger, nudge lamp out while pushing the tube back into AC120 chassis.

6. Unscrew lamp from socket and replace bulb.

7. Reinsert lamp & socket into tube.

8. Be sure to line up the lower flat sides of lamp socket with the double guides inside of lamp tubes. Lamp should seat all the way inside of tube inorder for light to shine through tube light hole.

9. Hold tube with one hand place tube cap on tube with the other hand and turn one click counter clockwise. Cap should not come off when pulling tube out.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

SAFETY INSTRUCTIONS (EUROPEAN)

The conductors in the AC power cord are colored in accordance with the following code.

GREEN & YELLOW—Earth BLUE—Neutral BROWN—Live

U.K. MAIN PLUG WARNING: A molded main plug that has been cut off from the cord is unsafe. NEVER

UNDER ANY CIRCUMSTANCES SHOULD YOU INSERT A DAMAGED OR CUT MAIN PLUG INTO A POWER SOCKET.

IMPORTANT! FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING: WATER AND MOISTURE: Appliance should not be used near water (near a bathtub, washbowl,

kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.

POWER SOURCES: The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance.

GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or polarization means of an appliance is not defeated.

POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.

SERVICING: The user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel.

FUSING: If your unit is equipped with a fuse receptacle, replace only with the same type fuse. Refer to replacement text on the unit for correct fuse type.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL!
