Wiring Considerations

Precautions

Observe these guidelines to avoid damage to the equipment and/or injury to personnel:
• The National Electric Code (NEC) governs the installation of electrical equipment. The provisions of
the NEC and other national, state and local codes must be observed.
• Do not connect or disconnect wiring while power is on.
• Do not connect or disconnect test equipment while the power is on.
• Connect the main power supply ONLY to L1 (R), L2 (S), and L3 (T). DO NOT connect main power
supply wiring to output terminals T1, T2, and T3.
• Connect motor power wires to T1 (U), T2 (V), and T3 (W) ONLY.
• Never touch the output circuit directly or place output wires in contact with the inverter enclosure or
any metal surface.
• Do not use power correction capacitors on the output of the drive.
• Motor wiring must be less than 328 feet (100 meters) in length.
• Motor wiring must be run in conduit separately from control and signal wires. If there is sensitive
equipment in the vicinity of the drive or motor, the conduit must be metallic, properly grounded.
• Control wiring must be less than 164 feet (50 meters) and in separate conduit or cable. Low voltage
wiring shall be wired with Class 1 wiring.

Inspection

After wiring is completed and at regular intervals, check:
• that all wiring is correctly installed
• that there are no loose screws or wire clippings inside the drive or enclosure
• that all screws are securely fastened
• that there are no loose strands in contact with other wires or other terminals.
