Power Requirements 
Optimux-XLT1 can be connected to 115 VAC or 220 VAC mains, or to a battery 
source supplying -48 VDC or 24 VDC. 
A second power supply is optionally installed in the Optimux-XLT1 to assure 
continuous operation in case of supply failure. When the two supplies are turned 
ON, they share the power consumption of the unit. If one of the power supplies 
fails, the other provides full power consumption. 
A limitation in the combination of interface installation exists due to the power 
supply currently installed in Optimux-XLE1. Table 1-3 shows the feasible 
combinations that can be ordered or installed.
