TERMINAL BLOCK TB1
WIRE AND TIGHTENING TORQUE SPECIFICATIONS
Copper Wire Size Range
(Solid or Stranded*) Stripping Length Tightening Torque Range
AWG mm 2 in mm in-lbs kg-cm
30 – 14 0.05 – 2.08 0.25 6 4.4 – 5.3 5.1 – 6.1
*If using stranded wire, be sure that all strands are contained in the terminal block
housing.
10.1 AC LINE INPUT AND GROUND
Connect the single-phase AC line input to TB1 Terminals "L1" and "L2". Connect the
Ground (earth) to TB1 Terminal "GND". See Figure 15, on page 26. For 208/230 Volt
AC Line input, be sure that Jumper J3 is not installed (factory setting). For 115
Volt AC Line input, install Jumper J3 (supplied). See Section 7.1, on page 19.
Note: The actual AC Line Input voltage must correspond to the setting of Jumper J3.
For 208/230 Volt AC Line Input, be sure that Jumper J3 is not installed. For 115 Volt
AC Line input, install Jumper J3 (supplied). Applying 230 Volts to the drive set for 115
Volt AC Line input will cause catastrophic failure.
10.2 MOTOR AND GROUND
Connect the Motor to TB1 Terminals "U", "V", and "W". Connect the Ground (earth) to
TB1 Terminal "GND". See Figure 15, on page 26.
Motor cable length should not exceed 100 feet (30 m) – special reactors may be
required – consult our Sales Department.
Be sure that the Current Limit is calibrated to the actual motor nameplate current
rating. Do not exceed the drive's maximum current rating.
Note: If the motor does not rotate in the desired direction, either: 1. Reverse any two
motor leads (with the AC Line disconnected and the motor stopped). 2. Change the
setting of the F-S-R Jumper, on CON2. See Section 7.4, on page 22. 3. If the
Forward-Stop-Reverse Switch is installed, reverse the connector installed on CON2.
See Section 6, on page 18.
