NOTICE
EMC Interference
Use screened cables for motor and control wiring. Separate the LHD mains input cable, motor cable, and control wiring.
Minimum 200 mm (7.9 in) clearance between power, motor, and control cables is required. Maximise this clearance to
minimise EMC emissions. This reduces the risk of interference between the LHD and other electronic devices.
