3.1 Main Circuit Wiring
Please observe the following instructions while wiring the main circuit.
·Do not bundle or run power and signal lines together in the same duct. Keep power andsignallines
separated by at least 300 mm.
·Use twisted-pair shielded wires or multi-core twisted-pair shielded wires for signal and encoder feedback
lines.
·The maximum length is 3 m for reference input lines and 20 m for encoder feedback lines.
·Do not touch the power terminals for 5 minutes after turning power OFF because high voltage may still
remain in the servo drive.
