Original Instructions
Wiring the ACS880 VFD
1. Wire the 3-phase wires and ground wire by using the following steps.
For each wire on the VFD, make sure that the terminal screw is not tightened.
Insert the wire into the terminal. Use a slotted screwdriver to tighten the
screw on the terminal. Tug the wire gently after tightening to make sure the
wire is secure in the terminal. (The ground wire uses a different type of
terminal. It also uses a Torx screwdriver.)
a) Place the black 3-phase wires into the three green input terminals on the
left-hand side of the bottom of the VFD. See Figure 15.
b) Place the black 3-phase wires into the three green output terminals on the
right-hand side of the bottom of the VFD. See Figure 15.
c) Connect the ground wire to the ground wire terminal using a Torx
screwdriver. See Figure 15.
The ground wire may connect to either ground terminal on the VFD.
The right-hand ground terminal to the right of the 3-phase output
terminals is easiest to reach.
