IMPORTANT PRECAUTIONS!
1. Carefully check the shipping carton for damage that may have occurred during
shipping. If the carton appears to be damaged, carefully inspect your unit for any
damage and be sure all accessories necessary to operate the system have arrived
intact. In the event damage has been found or parts are missing, please contact the
authorized dealer for further instructions.
2. To reduce the risk of electric shock, do not open the unit. There is no user
replaceable parts inside. Please contact the authorized dealer for any requirements
on technical support.
3. The AR3600I is a complex electronic instrument with various wiring options. You
cannot simply “plug in and go”. Take the time to read this manual, especially the
sections on Installation and Operation. For any questions in doubt, please contact

AR3600I DESCRIPTION
The AR-3600I is intended to protect computer, audio, video and other electronic equipment from
problems caused by AC line voltage irregularities - sags, brownouts or over voltages that can
cause sensitive digital equipment to malfunction, or, in extreme cases, to sustain damage. It
accepts single phase input AC voltages anywhere within two capture ranges, 88 to 134V (low
range) or 170 to 264V (high range) and converts them to the North American standard 120 volts.
The AR3600I will detect the different of the input voltage and automatically switch over to the
appropriate operating voltage range.Voltages outside the ranges may be converted to usable
levels, depending on how far out of range they are and what is considered usable. For example,
any voltage from 80 to 267 will be converted to 120V ±4%. See Figure 1.
The AR-3600I can handle loads totaling up to 30 amperes as long as the input voltage is equal
to or above 120 volts (low range) or 240 volts (high range). For voltages below those levels, its
capacity must be derated at approximately one-quarter ampere per volt. See Figure 2 below.
In live performance situations, where each act requires a special AC configuration, accidental
connection to incorrect AC voltages occurs surprisingly often with disastrous consequences.
Because of its dual range auto switch over capability, the AR-3600I can protect against a
catastrophic error in AC mains wiring. This feature also makes the AR-3600I ideal as a
component of a power distribution scheme suitable for worldwide use, accommodating national
voltages of 100, 120, 220, 240, or others, with equal ease and without the need for
readjustment.

The AR-3600I uses a design based on a 25-tap toroidal autotransformer. The
toroidal design assures minimal leakage of stray magnetic fields in a highly efficient,
compact package.
The AR-3600I’s circuitry monitors the incoming line voltage with each cycle. If a
voltage change requires that a different tap be selected, the new tap is electronically
switched in precisely at the zero-crossing, to avoid distorting the AC waveform. If
necessary, the AR-3600I can switch taps as often as once each cycle. Most
commercial voltage regulators using multiple-tapped transformers switch taps with
relays at uncontrolled times, thereby creating voltage spikes! And unlike voltage
regulators that employ Ferro resonant transformers, the AR-3600I is not sensitive to
small errors in line frequency, making it ideal for use with generators.
The AR-3600I has six convenience outlets on its rear panel, and one on the front
panel. All outlets are regulated, spike-suppressed, and filtered against RFI with a 3pole filter. There are no controls except a master circuit breaker, which serves as an
on-off switch. One or more units may be turned on remotely, either simultaneously or
in sequence, by switching an internally-derived DC control line.
The AR-3600I is housed in a three space (5.2” high and 17” deep) rack-mount
chassis, and weighs only 53 lbs (24 kg). It is made of extremely rugged heavy gauge
black powder coat steel. Allow it to be secured in both front and rear. It comes
equipped with a male IEC-309 power input and a female IEC-309 power link output
sockets.
AR3600I LIMITATIONS
AC power is, to some extent, unpredictable. The available voltage may vary
from place to place and from moment to moment. The waveform may not be a
perfect sine wave, and high or low frequency noise may be present. AC power
also varies from country to country in terms of voltage and frequency.
The AR3600I is intended to reduce to the greatest extent possible, the impact
of these irregularities. However, you should be aware that there are certain
things it cannot do. These include, but are not limited to:
1. Protecting against direct lightning strikes.
2. Protecting from complete loss of power (blackouts).
3. Performing frequency conversion from 50Hz to 60 Hz or vice versa.
4. Isolating ungrounded equipment.

INSTALLATION
SUPPLY CABLE WIRING
Because of the myriad differences in electrical code
requirements around the world, plus the varying cable
length needs in individual installations, it is not possible
to include a complete supply cable with your AR3600I.
Two cable-mount IEC-60309 connector, one each of
male and female type (Figure 7 & 8) that mates with the
AR3600I’s male IEC-309 power input and female IEC309 power link output sockets are supplied (Figure 3),
but it is up to the user to connect it to a cable with the
appropriate gauge, number of conductors, length, and source-end connector. This section
is intended to assist in determining the kind of cable to use, and in attaching it to the IEC309 socket.
SELECTING THE CABLE
For nominal 120 VAC operation, 3 conductor cable of at least 10 AWG* (.101”/2.56mm
diameter) should be used, depending on distance from the power source.
For nominal 220-240 VAC operation, 3 conductor cable of at least 14 AWG
(.064”/1.62mm diameter) should be used, depending on distance from the power source.
Rubber-jacketed cable is highly recommended for best flexibility and abrasion resistance.
It is permissible to use 4 conductor cable, but it is not necessary to do so and is not
recommended.
EFFECTS OF CABLE LENGTH
When dealing with high currents such as those handled by the AR3600I, the supply cable
itself must be considered part of the load. As such, the length, gauge, and temperature
rating of the insulation must be taken into account. The minimum wire gauges we suggest
may not be large enough when the cable run is longer than about 20 feet (7 meters). The
smaller the cable conductors are, the more fluctuation of input voltage there will be. This
is due to the greater voltage drop. For example, the recommended minimums will result in
a drop of approximately 1.0 volt for each 30 feet (10 meters) of cable.
Increasing the cable by one AWG size will reduce the drop to 1 volt per 45 feet (15
meters). Bigger is definitely better in this case.
SOURCE-END CONNECTOR
The connector used at the source end should be rated at least 220V-15A for high range
operation, or 120V-30A for low range operation. If in doubt, consult a licensed electrician
when installing your AR3600I.
