or computer rackmount system requiring clean,

filtered, and regulated AC power for optimum

operation.

MPORTANT SAFETYNSTRUCTIONS

PLEASE READ PRIOR TO INSTALLATION1. Please read and observe all of the safety and

operating instructions before the AR-1215 or

AR-2306 is operated. Retain these

instructions for future reference.

2. The AR-1215 or AR-2306 should

not be used near water for ex-

ample, near a bathtub, kitchen sink,

in a wet basement, near a swimming pool, etc.

3. Do not place the AR-1215 or AR-2306 near

heat sources such as radiators, heat registers,stoves, or other appliances that produce heat.

4. Route the power cord and other cables so that

they are not likely to be walked on, tripped

over, or stressed. Pay particular attention to

condition of cords and cables at plugs, and the

oint where they exit from the AR-1215 or AR-

2306. To prevent risk of fire or injury, damaged

cords and cables should be replaced immedi-

ately.

5. Clean the AR-1215 or AR-2306 with a damp cloth

only. Do not use solvents or abrasive cleaners.ever pour any liquid on or into the unit.

6. When left unused for a long period of time, the

ower cord of the AR-1215 or AR-2306 should

e unplugged from the outlet.

7. The AR-1215 or AR-2306 should be serviced

y qualified service personnel when:a. e power supp y cor or e p ug as een

raye , n e , or cu .

b. Objects have fallen or liquid has spilled into

e un .

8. The AR-1215 or AR-2306 requires that a safety

ground be present for proper operation. Any

attempt to operate the AR-1215 or AR-2306

without a safety ground is considered improper

operation and could invalidate the warranty.

9. There are no user serviceable parts in the AR-

1215 or AR-2306. Refer servicing to qualified

service personnel only.

DEFINITIONSVOLTAGE REGULATION: The AC line voltage is a

number indicating the nominal electrical potential

electrical equipment of all kinds. In most of North

America it is 117 volts AC; in Japan, 100 volts; andn many o er coun r es , , or vo s. e

actual voltage can fall below or rise above this nomi-

nal level due to brownouts, power cutbacks, use of

tions can cause poor performance or a malfunction.

A regulator is a device which, through use of a trans-

ormer, correc s e vo age ev a on y s epp ng

or transients) are absorbed by special components

RFI/EMI INTERFERENCE: Noise from RFI (Radio

requency n er erence or ec ro agne c

Interference) involves lower voltages and less

energy than is found in spikes, but it is continuous

physical damage, but it can certainly be annoying,

producing static in audio circuits, snow on video

certain kinds of lighting, electric motors, and others.

ecause no se occurs a g er requenc es an

through use of low-pass filtering.

EXTREME VOLTAGE PROTECTIONThe AR-Series includes special circuitry to sense
