6 IEC Mains Connector

rear panel legend

This is a standard IEC power connector. An AC mains cord having the appropriate AC plug and ratings for the intended operating voltage is included in the carton.

Warning - all apparatus with class 1 construction shall be connected to a mains socket outlet with a protective earthing connection.

U.S. DOMESTIC AC MAINS CORD

The mains cord supplied with the unit is a heavy-duty, three- conductor type with a conventional 120 VAC plug with ground pin. It should be connected to an independent circuit capable of continuously supporting at least 15 amps.This is particularly critical for sustained high-power applications. If the outlet used does not have a ground pin, a suitable grounding adapter should be used and the third wire grounded properly.

Never break off the ground pin on any equipment. It is provided for your safety.

The use of extension cords should be avoided but, if necessary, always use a three-wire type with at least a #14 AWG wire size.The use of lighter wire will severely limit the power capability of this amplifier. Always have a qualified electrician install any new electrical equipment.To prevent the risk of shock or fire hazard, always be sure that the amplifier and all associated equipment is properly grounded.

NOTE: FOR U.K. ONLY

If the colors of the wires in the mains lead of this unit do not correspond with the colored markings identifying the terminals in your plug, proceed as follows: (1) The wire that is colored green and yellow must be connected

to the terminal that is marked by the letter E, the Earth symbol, colored green or colored green and yellow. (2) The wire that is colored blue must be connected to the terminal that is marked with the letter N or the

color black. (3) The wire that is colored brown must be connected to the terminal that is marked with the letter L or the color red.
