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 IEC-
309 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 IEC-
309 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.
