Warning! Do not wire switches or relays in
series with the armature. Armature switching
can cause catastrophic failure of motor and/or control.
A. AC Line Connection – Wire the AC line to L1
and L2 terminals, as shown in Figure 4.
B. Permanent Magnet (PM) Motor Connection –
Wire the motor armature leads to A+ and A- termi-
nals, as shown in Figure 4. On dual voltage mod-
els, be sure that Jumper J1 is set to the corre-
sponding motor voltage. Be sure that the correct
Plug-In Horsepower Resistor® is installed (see
Table 3, on page 12). Note: If the motor runs in
the opposite direction than is desired,
disconnect power and reverse the motor
leads.
C. Main Speed Potentiometer
Connection – The control is supplied
with a Main Speed Potentiometer.
Connect the Main Speed Potentiometer
high side to P3 terminal, wiper to P2
terminal and low side to P1 terminal, as
shown in Figure 5. Rotating the Main Speed Potentiometer clockwise will
increase motor speed. Rotating the Main Speed Potentiometer counterclock-
wise will decrease motor speed.
D. Voltage Following Connection – A 0 - 5 Volt DC analog signal voltage can
also be used to control motor speed. See Figure 6, on page 14. Connect the
