4. Once you have determined that the board is acceptable, select the
appropriate AC line voltage, as described in the next section.
Setting the AC Line Voltage
Caution:
Be sure to set the AC line voltage for the voltage you are using before
connecting the ERB-24 to line power. The default setting is 115 V.
The 115/230 AC Line Voltage Selector is a 2-position slide switch located as
shown in Figure 3-1. To change the line voltage setting, slide the switch to the
appropriate setting (115 V or 230 V) marked on the switch.
Figure 3-1. ERB-24 Board Layout
Once you have set the AC line voltage, you can attach accessories and wire appli-
cations to the ERB-24 board, as discussed in Chapter 4.
