The Drive leaves the factory with all parameters set for 2-Wire external reference control. Figure 1-5
must be used for all external connections.
To use the Drive in a 3-Wire application, Drive parameters n01, n02, and n03 must be
reprogrammed, using the Digital Operator. Figure 1-6 must then be used for all external connections.
A. Main Circuit Input/Output
Complete wire interconnections according to Tables 1-1 and 1-2; observe the following:
• Use 600 V vinyl-sheathed wire (75°C copper) or equivalent. Wire size should be determined
considering voltage drop of leads.
• NEVER connect AC main power to output terminals T1 ( U ), T2 ( V ), and T3 ( W ).
• NEVER allow wire leads to contact metal surfaces. Short-circuit may result.
• NEVER connect power factor correction capacitors or noise filters to Drive output.
• SIZE OF WIRE MUST BE SUITABLE FOR CLASS I CIRCUITS.
• Use only factory supplied installation instructions to install optional dynamic braking resistors.
Failure to do so may cause equipment damage or personal injury.
• Motor lead length should NOT EXCEED 164 feet (50 meters), and motor wiring should be run in
a separate conduit from the power wiring. If lead length must exceed this distance, reduce
carrier frequency and consult factory for proper installation procedures.
• Use UL listed closed loop connectors or CSA certified ring connectors sized for the selected wire
gauge. Install using the correct crimp tool recommended by the connector manufacturer.
