Most probably the 60 Hertz frequency refers to the mains power supply frequency,
hence this only confirms that the appliance is designed to work on a mains 
power supply of 60  Hertz (cycles per second).

As an example in my country, Malta, we have a mains voltage of 240 Volts and
a frequency of 50 Hz.
