2.3.1 Connecting to Peripheral Devices
This section shows a standard example of connecting Σ-Series products to peripheral de-
vices and briefly explains how to connect to each peripheral device.
NOTE Read the following notes before wiring:
• Connect only one cable to one terminal. Never connect two cables to one terminal.
• Do not solder the cable.
• Peel back the cable shield by about 10mm (0.39in.) min. Then insert the cable into the
terminal securely and tighten the screw. Never leave the bare wires outside of the ter-
mianl.
• When the cable is inserted into the flat terminal, use the following ferrules.
