NOTES:
1. Program TB-13C (Parameter 12) for START FORWARD (05).
2. If reverse direction is required, set ROTATION (Parameter 17) to FORWARD AND REVERSE
(02), and program TB-13A (Parameter 10) for START REVERSE (06).
3. Momentarily close TB-13C to TB-11 to START in the forward direction, or close TB-13A to

WARNING!
Hazard of electrical shock! The SM-Basic control terminals are not isolated from line voltage!
Line voltage is present between the control terminals and ground. Do not touch!
Disconnect input power and wait three minutes before making connections to the control terminals.
Devices (such as switches, pushbuttons, potentiometers, relays, etc) and wiring connected to the
control terminals are hot to ground and must have an insulation rating of at least 240 Vac or a
dielectric rating of at least 1500 volts to prevent damage to equipment and/or injury to personnel.
