SECTION 3 

INSTALLATION 

 

28 

 CAUTION 

 
 

 
 

Use of equipment connected to improper input voltage may cause permanent damage 

and void the warranty 

3.5 INSTALL 

UPC

 

 

NOTE:

 Most users will not need to concern themselves with the following installation issue if the UPC is 

packaged with a power source. 
 
Install the UPC with 2 nuts attaching the UPC front panel to the SCU front panel.  See figure 3.5. 
 
Install LED PCB with 4 nuts, attaching the LED PCB to the SCU front panel. 
 

 

3.6 

INSTALL CABLING AND COVER

 

 

NOTE:

 Most users will not need to concern themselves with the following installation issue if the UPC is 

packaged with a power source. 
 

•

  Connect J2A of the UPC to P2A of the SCU. 

•

  Connect J3A of the UPC to P3A the LED PCB. 

•

  Connect J3B of the SCU to P3B of the LED PCB. 

•

  Attach J4 from the UPC to the rear panel of the SCU. 

•

  Attach J5 from the UPC to the rear panel of the SCU. 

•

  Connect J6A of the SCU to P6A of the UPC INTERFACE PCB. 

•

  Place the top cover on top and install six screws. 

 
 

3.7 

CONNECT INPUT SERVICE

 

 

Verify that the Input Power Circuit Breaker on the front panel is off.  Connect the Input Line Cord to the 
back of the SCU chassis.  Verify the 115/230 volt switch on the rear panel is set to the correct position.  
Input frequency may be 50 - 400 Hz. 
 
 
Turn the Input Circuit Breaker ON.  Refer to section 4 to verify proper operation.
