Voltage Switches
• Set voltage switch SW501 to either 115 or 230 to match the
AC line voltage (see Figure 4 below).
• Set voltage switch SW502 to either 90 or 180 to match the
maximum armature voltage (see Figure 4 below).
Field Output
The field output is for shunt wound motors only. Do not make
any connections to F1 and F2 when using a permanent magnet
motor. Use 18 AWG wire to connect the field output to a shunt
wound motor. Table 2 lists the field output connections.
