AC power system description
This section describes the characteristics of the Meridian SL-1 system where
equipment columns are 
 powered by commercial power.
The commercial power voltage is brought directly into the Pedestal Power
Distribution Unit. From there it is passed through separate wiring to the
individual modules in order to provide power to the module power supplies.
Input power specifications
AC power supplies operate at a nominal 2081240 V. A typical system
operating from 208 V using four 
 
 draw 15-24 Amps, depending on
the configuration. These are fed from a central point in the pedestal, access to
these connections is provided and should be used to confirm that the line 
voltage is within the required range as indicated in Tables 1 and 2.
