CONNECTION
G. Remote Start/Stop Switch – A remote Start/Stop Switch can be installed by removing the
wires from the "Start," "Com" and "Stop" terminals, and reconnecting them to a remote
switch. (See Fig. 9) Note: To eliminate Start/Stop function, join the "Start" and "Com"
Quick Connect terminals with a jumper.
H. Inhibit – The control can be
electronically stopped and started with
the Inhibit circuit. To "Stop" the
control, Terminals I1 & I2 must be
joined via a contact. The control can
be restarted by opening the contact.
(See Fig. 10A)
Note: The Inhibit Circuit is not
isolated. Do not common or
ground inhibit leads.
I. Enable – The control can also be
started and stopped with an Enable
circuit (the Enable circuit functions
opposite to that of the inhibit circuit;
Inhibit: open to start, close to stop,
Enable: open to stop, close to start).
The Enable function is established by
wiring a contact in series with the violet
potentiometer lead connected to
terminal P3. (See Fig. 10B) The
Enable circuit is not isolated. Do not
common or ground wiring.
WARNING! Do not use
Start/Stop, Inhibit or Enable
functions as a safety disconnect. Use
only an AC Line disconnect for that
purpose.

Note: The MIN speed trimpot must not be set higher then 70% CW rotation (approx.
2:00 o'clock position) or Enable will not function.
VI. FUSING. (See Fig. 5, p. 8)
A. AC Line Fusing – Most electrical codes require that each ungrounded conductor contain
fusing. Separate branch circuit fusing, or circuit breaker may be required. Check all
electrical codes that may apply to the installation. This control does not contain AC line
fuses. A 25 amp rated fuse or circuit breaker can be used.
B. Armature Fusing – It is suggested that an armature fuse be installed in series with an
armature lead. Use a 25 amp 250V rated fuse or circuit breaker.
