WARNING!

• DO NOT connect incoming AC power to output terminals U, V, W, or terminals B+,

B-! Severe damage to the drive will result.

• Leakage current may exceed 3.5 mA AC. Minimum size of the protective earth

(PE) conductor shall comply with local safety regulations for high leakage current

equipment.

NOTE

• WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL APPLICABLE

LOCAL CODES.

• Motor wires MUST be run in a separate steel conduit away from control wiring and

incoming AC power wiring.

• Do not install contactors between the drive and the motor without consulting Lenze

Americas for more information. Failure to do so may result in drive damage.

• Use only UL and CSA listed and approved wire.

• Minimum wire voltage rating is 300 V for 120, 208, and 240 Vac systems, and 600

V for 400 and 480 Vac systems.

• Wire gauge must be based on a minimum of 125% of the rated input/output current

of the drive, and a minimum 75°C insulation rating. Use copper wire only.
