1]  The Mains Input 

 
 
As a safety precaution your SOC 1.1 is shipped without a mains fuse fitted.  
Before use, you must select the correct mains voltage for your local supply 
on the rear panel and fit the correct mains fuse type into the fuse draw for 
that voltage. 
 

 

Setting the Voltage Selector… 

 
You will need a flat blade screwdriver. 
 
If your mains voltage is 110V to 120V set the rear panel voltage selector to 120V. 
If your mains voltage is 220V to 240V set the rear panel voltage selector to 240V.

 

 
POWERING UP THE SOC 1.1 WITH THE WRONG VOLTAGE SETTING MAY CAUSE 
SEVERE INTERNAL DAMAGE !! 
 

 

Selecting the Correct Fuse… 

 

In the supplied accessories bag you will find; 
 
2x  1.5 Amp slow blow fuses, FIT for 220V to 240V. 
2x  2.5 Amp slow blow fuses, FIT for 110V to 120V.

 

 

Slide out the fuse draw above the IEC power inlet and insert the appropriate fuse into the 
carrier clip.  Note there is also a position in the carrier for a spare fuse (the square tube bit) 
and we suggest you store the second supplied appropriate fuse here. 

 

 

Please Note… 

 

Fitting the wrong fuse may result in the fuse blowing on power up or inadequate protection. 
 
Fitting fast blow type fuses may also result in the fuse blowing on power up. 
 
Your dealer may have already set all this up for you but it pays to check it before powering 
up the SOC 1.1.
