Connection 
The mains power connection is located at the rear of the instrument. 
Before connecting the instrument to the power supply, ensure both 
the instrument and the power supply are turned OFF, and that the 
voltage selector switches on the instrument rear panel (Cary 100/300 
only) are set to the correct mains power supply voltage (refer to the 
table on the rear panel of the instrument). 
You should also check the fuses before connecting the instrument to 
the mains power supply to make sure they are the correct type and 
rating for your location. There are two operator accessible fuses 
located at the rear of the instrument. See Page 41 for instructions on 
how to check the fuses. 
To connect the instrument to the mains power supply, plug the mains 
power cord into the back of the instrument and the free end of the 
power cord into the mains power supply, and then switch on the 
mains power supply. 
Turning on the system

  You have connected the components of the system to one 
another, checked the setting of the voltage taps and connected
