Cautions 

4.1 Concerning the DDC power supply   

 

The supply voltage from the DDC power supply is supplied to each output of the VG-881. 
The maximum current supplied by the DDC power supply is described below.

Caution 

●

 

The DDC power supply incorporates an overcurrent protection device, but do 

not use a current which exceeds the rating. 

●

 Do NOT supply power to the DDC power supply from the device connected to 

the VG-881. If such the voltage of such a power supply is connected, both the 
VG-881 and the connected device may fail.
