• Wire correctly after confirming the signal names of all terminals.
• Note that stranded wire should be processed with insulation-covered
ferrule (DIN 46228-4 standard compatible-type) at its ends before
using for connection.
• Tighten screws for communication and I/O connectors correctly at
0.25…0.3 N•m (2.21…2.66 lb•in).
