Installation of Neutral Resistor Assembly
(Drives with Common Mode Chokes)
On top of the converter cabinet, a sheet metal enclosure containing
power resistors is to be installed.
1. Locate the resistor assembly on top of the cabinet as shown in
Figure 2.6. (For acoustic hood assembly, refer to Figure 2.7.)
2. Affix the assembly to the top plate using M6 thread forming
screws provided.
3. Remove the top plate of the resistor assembly to permit access to
the wiring connection points.
4. Connect the resistor wiring and per the electrical diagram
provided with the drive, a typical connection diagram is shown
in Figure 2.6. Ensure that the resistor wiring is routed through
the hole having a plastic bushing to protect the wire insulation.
The neutral resistor assembly housing has a ground connection
that is to be connected to the top plate of the drive.
5. Re-install the top plate of the neutral resistor housing.
