Selecting the AC Input Voltage
The voltage is set to 115 V when shipped. To change the voltage, you
must reset the jumpers located to the right of the AC power cord
connection.
Table 2 shows the input voltage selection.
To change the voltage from 115 V to 230 V, proceed as follows:
1. Remove the jumper from E3 to E5.
2. Leave the jumper E2 to E4 as it is.
3. Disconnect the jumper end from E1 and move it to E5 so it jumpers
P2 to E5.
To change the voltage from 115 V to 24 V, proceed as follows:
1. Disconnect the jumper end from E5 and move it to E7 so it jumpers
E3 to E7.
2. Disconnect the jumper from E4 and connect it to E6, so it jumpers
E2 to E6.
3. Leave the jumper P2 to E1 as it is.
