7.2 – MOTOR CONNECTION
Connect the motor to Terminal Block TB1 Terminals U, V, W.
See Figures 11 – 13 on pages 15 and 16.
Motor cable length should not exceed 100 feet (30 m) – special
reactors may be required – contact Technical Support. Be sure Jumper
J2 is set to the corresponding motor horsepower rating, as described
in Section 10.2 on page 19.
7.3 – GROUND CONNECTION
Connect the Ground Wire (Earth) to the Green Ground Screw.
The Ground Screws are located next to Terminal Block TB1.
See Figures 11 – 13 on pages 15 and 16.
7.4 – REMOTE MAIN SPEED POTENTIOMETER CONNECTION
The drive is supplied with a prewired Main Speed Potentiometer
mounted on the front cover. To operate the drive from a remote
potentiometer (5 k
Ω
), remove the white, orange, and violet
potentiometer leads from Terminals P1, P2, P3. The wires may be
taped and left inside the drive. The potentiometer assembly may be
removed if a watertight seal is used to cover the hole in the front cover.
Connect the Main Speed Potentiometer to Terminals P1 (low side), P2
(wiper), and P3 (high side). See Figure 14.
WARNING!
Do not earth ground any Main Speed Potentiometer terminals.
Application Note:
If it is required that the Remote Main Speed Potentiometer be isolated from the AC Line, install the Signal Isolator.
See Section 14 on page 23.
