3. WIRING
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 and signal lines
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 is 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 servodrive.
