Drive Installation
The following table identifies general wire categories that will be encountered when installing the
PowerFlex 7000 "A" Frame Drive. Each category has an associated wire group number that is used in the
following sections to identify the wire to be used. Application and signal examples along with the
recommended type of cable for each group are provided. A matrix providing the recommended minimum
spacing between different wire groups run in the same tray or separate conduit is also provided.

Note 1: Steel conduit or cable tray may be used for all PowerFlex 7000 "A" Frame Drive power or control wiring, and steel conduit is required for all PowerFlex
7000 "A" Frame Drive signal wiring. All input and output power wiring, control wiring or conduit should be brought through the drive conduit entry holes of the
enclosure. Use appropriate connectors to maintain the environmental rating of the enclosure. The steel conduit is REQUIRED for all control and signal circuits,
when the drive is installed in European Union countries. The connection of the conduit to the enclosure shall be on full 360 degree and the ground bond at the
junction shall be less than 0.1 ohms. In EU countries this is a usual practice to install the control and signal wiring.
Note 2: Spacing between wire groups is the recommended minimum for parallel runs of 61 m (200 feet) or less.
Note 3: The customer is responsible for the grounding of shields. On drives shipped after November 28/02, the shields are removed from the drive boards. On
drives shipped prior to November 28/02, all shields are connected at the drive end and these connections must be removed before grounding the shield at the
customer end of the cable. Shields for cables from one enclosure to another must be grounded only at the source end cabinet. If splicing of shielded cables is
required, the shield must remain continuous and insulated from ground.
Note 4: AC and DC circuits must be run in separate conduits or trays.
Note 5: Voltage drop in motor leads may adversely affect motor starting and running performance. Installation and application requirements may dictate that
larger wire sizes than indicated in IEC / NEC guidelines are used.
