2-2-2 Precautions when Wiring
• Separate signal leads and power lines in order to protect the E5ZN and its
lines from external noise.
• We recommend using solderless terminals when wiring the E5ZN.
• Tighten the terminal screws using a torque between 0.40 and 0.56 N·m.
• Use the following type of solderless terminals for M3 screws.
