Selecting the AC Input Voltage
The voltage is set to 115 V when shipped. To change the voltage, you
must reset the jumpers to the right of the AC power cord connection.
Table 4 shows jumper settings for the three voltages.
To change the voltage from 115 V to 24 V, proceed as follows:
1. Disconnect the jumper end from E4 and move it to E3 so it jumpers
E1 to E3.
