Connection Procedure - ABB ACQ580-01 Quick Installation And Start-Up Manual



Connection procedure

1. Prepare the power cables (shielded cable).
•
Prepare the ends of the input power cable and motor cable as illustrated in the figure below.
•
Install the cord grips and the grounding shelf. For easier installation, don't install (or remove) the top section of
the shelf until after the power cables are installed. The top section is for control wires.
•
Slide the cables through the grip. After wires are terminated, complete installation by tightening the cord grip
to achieve a water-tight seal.

2. Connect the power cables. For the tightening torques, refer to
•
Connect the conductors:
•
Connect the phase conductors of the motor cable to terminals T1/U, T2/V and T3/W. Connect the twisted
shield of the cable to the grounding terminal. (3a)
•
Connect the phase conductors of the input power cable as was done for the motor cabling. Use terminals L1, L2
and L3 if no disconnect option is present
cable conductors to the disconnect switch at terminals 2T1, 4T2 and 6T3. (3b)
•
If used, connect the brake resistor cables.
3. Secure the conduit (if used) outside the unit mechanically. In wet, dirty, dusty, corrosive or similar locations, all cord
grips must be properly tight and secured such that no leakage can occur.
4. Ground the motor cable shield at the motor end. For minimum radio frequency interference, ground the motor cable
shield 360 degrees at the cable entry of the motor terminal box.
