Unpacking and Installation 

 

3.1 Unpacking 

 
Carefully remove the IBU-240 from the shipping carton.  The following items 
should be included in the shipment: 

 1 

IBU-240 

  1 power cord 

  1 user guide 

 

Note the power entry module on the rear of the IBU-240 chassis.  Please take 
note of the voltage displayed on the rear of the power entry module and verify 
that the voltage matches the local line’s voltage. 
      

   

  

   

CAUTION:

  

  THE IBU-240 WILL BE DAMAGED IF THE INCORRECT AC LINE    
  SETTING IS USED. 

 
 
 

  

   

WARNING:

 

  REMOVE THE POWER CORD FROM THE IBU-240 BEFORE    
  ADJUSTING THE LINE VOLTAGE.

 

 
 
If the AC line setting is incorrect, detach the power cord from the power entry 
module.  Use a small screwdriver to lift up the fuse cover on the power entry 
module to remove the fuse holder.  Reverse the fuse holder and re-insert the 
fuse holder, making sure that the correct AC line voltage is now displayed on the 
rear panel.
