5.1.4.5 
AC Line Fuse 
The power supply has one line fused in the single line fuse on the line (Hot) wire of the AC 
input. The input fuse is a slow blow type. AC inrush current does not cause the AC line fuse to 
blow under any conditions. Not all protection circuits shall cause the AC fuse to blow unless a 
component in the power supply has failed. This includes DC output load short conditions.

670W DC Output Specifications 
5.1.5.1 Grounding 
The output ground of the pins of the power supply provides the return path. The output 
connector ground pins is to the safety ground (power supply enclosure).  
5.1.5.2 
Output Voltage and Currents 
The following tables define two power and current ratings for the 670W power supply. The 
combined output power of all outputs shall not exceed the rated output power.
