SIMPLIFIED OPERATING INSTRUCTIONS
WARNING! Disconnect main power when making connections to the control.
A. AC Line Connection
– Connect the AC line to L1 and L2 terminals of Terminal Block TB1
and the ground wire (Earth) to the green ground screw as shown in Figure 4, on page 6, and
as described in Section IIA, on page 6, and Section IIB, on page 6. Set Jumpers J1 and J2
to the corresponding AC line input voltage (115 or 208/230 Volts AC).
as described in Section IIA, on page 6, and Section IIB, on page 6. Set Jumpers J1 and J2
to the corresponding AC line input voltage (115 or 208/230 Volts AC).
B. Motor Connection
– Connect the motor to U, V and W terminals of Terminal Block TB1
as shown in Figure 4, on page 6, and as described in Section IIC, on page 6.
C. Start/Stop Switch
– The control is supplied with a prewired Start/Stop Switch as
described in Section IIE, on page 6, which is used to start and stop the control. In Manual
Start Mode, this switch must be used to start the control each time the AC power is lost or
the control shuts down due to a fault.
Start Mode, this switch must be used to start the control each time the AC power is lost or
the control shuts down due to a fault.
D. Jumper Settings
– All jumpers are factory set for most applications. Be sure Jumper J3
is set to the correct motor HP. See Section IIIB, on page 7.
E. AC Line Fusing
– Install a fuse or circuit breaker in the AC line. Fuse each conductor
that is not at ground potential. See Section VII, on page 10, for recommended fuse size.
F. Trimpot Settings
– All trimpots have been factory set as shown in Figure 2, on page 3.
Trimpots may be readjusted as described in Section VIII, on page 10.
G. Diagnostic LEDs
– After power has been applied, observe the LEDs to verify proper con-
trol operation as described in Section IX, on page 13.

ii. SAFETY WARNING! Please read carefully
This product should be installed and serviced by a qualified technician, electrician, or elec-
trical maintenance person familiar with its operation and the hazards involved. Proper installa-
tion, which includes wiring, mounting in proper enclosure, fusing or other overcurrent protection,
and grounding can reduce the chance of electrical shocks, fires, or explosion in this product or
products used with this product, such as electric motors, switches, coils, solenoids, and/or
relays. Eye protection must be worn and insulated adjustment tools must be used when work-
ing with control under power. This product is constructed of materials (plastics, metals, carbon,
silicon, etc.) which may be a potential hazard. Proper shielding, grounding, and filtering of this
product can reduce the emission of radio frequency interference (RFI) which may adversely
affect sensitive electronic equipment. If further information is required on this product, contact
the factory. It is the responsibility of the equipment manufacturer and individual installer to sup-
ply this Safety Warning to the ultimate end user of this product. (SW effective 11/1992.)

This control contains electronic Start/Stop circuits that can be used to start and stop the con-
trol. However these circuits are never to be used as safety disconnects since they are not fail-
safe. Use only the AC line for this purpose.
