3.1 Main Circuit Wiring
Please observe the following instructions while wiring the main circuit.
！
CAUTION
·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.
