Hardware Installation Guidelines

Power Wiring Precautions

• Verify complete power lock-out on 3-phase 200-480 VAC lines prior to terminal block engagement.
• Maintain strict grounding of the drive frame chassis using dedicated low-impedance copper conductors.

Signal Cable Routing

• Route differential encoder wiring inside grounded steel conduits separated from high-voltage AC lines.
• Keep analog +/-10 V control signal runs below standard maximum lengths to reduce electromagnetic interference.
