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.
