WIRING CONNECTIONS, 15-25 kW<br />
SINGLE PHASE ALTERNATORS<br />
The most popular single phase connection is the<br />
120/240combination. With this connection either 120<br />
or 240 volts can be used alone or at the same time<br />
(Figure 41).<br />
Refer to <strong>page</strong> 8for wiring connections of 30 kW units<br />
using the UR control.<br />

THREE PHASE ALTERNATORS<br />
Three phase alternators are connected as shown in<br />
Figure 42. The three load wires are connected to T1,<br />
T2 and T3. Single phase (240 volts) can be obtained<br />
between any two three-phase terminals. Single phase<br />
(120volts) can be obtained between T1 and TO or T2<br />
and TO. TO is the grounded terminal for 120 volts.<br />
