Electrical Installation
Chapter Objectives
This chapter provides information on electrical installation of a PowerFlex
Drive Package for Fan and Pump Applications.
Power Wire Size
Requirements
Wire size should be determined based on the size of the conduit openings,
and applicable local, national and international codes such as NEC/CEC.
Power Terminal Block
Specification
Input power wiring should be sized according to applicable codes to handle
the drive's continuous-rated input current. Output wiring should be sized
according to applicable codes to the handle the drive's continuous-rated
output current. See Table 5.A
for the range of power wire sizes that the
terminals can accommodate.

ATTENTION: National codes and standards (NEC, VDE, BSI,
etc.) and local codes outline provisions for safely installing
electrical equipment. Installation must comply with specifications
regarding wire types, conductor sizes, branch circuit protection,
and disconnect devices. Failure to do so may result in personal
injury and/or equipment damage.
