• Separate input leads and power lines to protect the EJ1 from external
noise.
• Use AWG22 (cross-sectional area: 0.326 mm
2
) to AWG14 (cross-sec-
tional area: 2.081 mm
2
) twisted-pair cable for power supply and AWG28
(cross-sectional area: 0.081 mm
2
) to AWG16 (cross-sectional area:
1.309 mm
2
) for all other cables. The stripping length is 6 to 8 mm.
• Use crimp terminals when wiring the terminals.
• Tighten the terminal screws to a torque of 0.40 to 0.56 N·m.
• Up to two wires of the same size and same type or two crimp terminals
can be inserted into a single terminal.
• Use the following types of crimp terminals for M3 screws.
